Xavier P. Mrs Laly Mathew Mrs. Professor Dept. No part of this dissertation has been presented earlier for any degree, diploma or similar title of any other University or institution.Given the level of genetic differentiation north and south of the Palghat Gap, we suggest that these populations be considered two different taxonomic species. We did not attempt to account for repeated measures by year, and found no significant year effects. The ability to fly enables the birds to move actively and with comparative ease from one habitat to another. The feathers covering the body of a bird fall into three classes. Three hundred and fifteen species were recorded in periyar tiger reserve Robertson and Jackson, Because this sanctuary are near to Pampadum Shola National Park and lies in almost same altitude and similar vegetation as that of Pampadum Shola National Park. This may be due to the similar reasons that found in the case of Kurinjimala sanctuary and Mannavan Shola, that is vegetation, climatic factors and altitude. Because they cannot reproduce successfully in the conditions of intense cold or in adequate food. Robin investigated how ancient geographic gaps and glacial cycles have partitioned genetic variation in modern populations of a threatened endemic bird, the White-bellied Shortwing Brachypteryx major, across the montane Shola forests on these islands and also inferred its evolutionary history.

Influences of population size and woodland area on bird species distributions in small woods. Eventually the pair starts mating and nest building. The area of territory defended by a pair depends upon location, abundance of food, natural barriers etc. In different season birds depends new territories, some birds retain same territories. The most out standing way that birds have adapted is, ofcourse,the conversion of their upper limbs into wings, the growth of feathers and ability of fly. Birds have developed specialized bills and feet for feeding. The most generalized bill perhaps belongs to the omnivorous crow. It is a straight, pointed and roughly triangular in section. Dabbling ducks have widened bills with lamination on edges of the upper and lower mandibles. This adaptation is especially for plankton-sieving shovellors, and the larger spoon bills and flamingoes. Shore birds have thin, elongated bills for probing the mud in search for small animals. Birds of prey have developed deeper, shorter and down curved bills for tearing and piercing flesh. But for them perhaps the most important piece of hunting equipments is their feet. Strong, dagger-shaped bills for chiseling wood and prising insets from cervices and beneath bark for wood peckers. Birds which feeds on flower nectors also have well adapted long pointed thin beak. A much large no. Grewal, Of the senses, those of sight and hearing are most highly developed in birds, that of taster comparatively poor, while smell is practically absent. In rapid accommodation of the eye, the bird surpasses all other creatures. The focus can be altered from a distant object to near one almost instantaneously;as an American naturalist puts it, in a fraction of time it the eye can change itself from a telescope to a microscope. Salim Ali, 12 About the breeding habits; all birds are oviparous ie, they propagate by means of eggs. Breeding season is different for most species, each species has a particular breeding period, usually a few weeks in spring or summer. Breeding activities follow increase in the size and functioning of the gonads and are controlled by the endocrines. Breeding season begins with the males uttering their characteristics songs at frequent internals, and many go through courtship performances in the presence of females. Then begins their annual cycle of family life including, courtship, mating, nest-building, egg laying, incubation and care of the young. Both sexes or only one sex performs all the activities. Bird migration is one of the fascinating aspects of behaviour. Many species migrate locally or over long distances to avoid adverse climatic conditions and in search of food. There are few birds which are seen only during a definite period of the year and they disappear for the rest of years. The periodical movement called migration seen mostly in harsher winter conditions or the scarcity of food. Because they cannot reproduce successfully in the conditions of intense cold or in adequate food. Thus they usually desert their nuptial grounds before such conditions appear; they migrate from their contranuptial wintering places. Migration is the greatest adventure in the birds life. Their total value in flesh and eggs is great. Utility of some birds, such as vultures and adjuvant storks, as scavengers must not be overlooked. They render invaluable service by eating large quantities of offal and refuse, which , if allowed to decompose under the influence of a hot sun, would give rise to pestilence. Their value in consuming insect and weed seed pests should not be 13 underrated. Hawks and owls help control vermin that might otherwise over run agricultural crops. Man has not only hunted birds for food and plumage;he has also worshipped them as gods and used them as symbols in art. Man could certainly have a hard time getting along without his avian comrades. Birds cause hazardous to humans by harboring parasitic pathogens either externally or internally. Diseases transmitted by birds are known as ornithosis. Some diseases spread by birds are psittacosis. This causes respiratory ailments in humans; it is caused by parrots, sparrows. Avian pox; this is reported in domestic chickens. The infection is seen in throat and nasal passage of birds. One of the saddest features of civilization has been the disappearance extinction of so many beautiful and curious creatures from this world of ours. So this birds need protection from the great tide of destruction. For that strict rules are needed like restriction of killing of game birds and so on. Tiwari , 14 Review of literature Kerala has along history of ornithological surveys. Based on the birds collected by Fulton and Frank bourdillion, A. O Hume wrote two papers in stray feathers Hume,; Ferguson,a tea planter, collected birds and wrote a series of paper in journal of Bombay natural history society Ferguson and bourdillion,, Jayson et al. Two hundred and fortynine species of birds are recorded in the reserve. Sixty species are new records for Periyar while 3 are new records for Kerala. The lesser number of wetland birds may be due the absence of marshes and shallow water areas in the Lake. Rarity of larger birds of prey may be due to their low population in nature or the agricultural practices in the surrounding areas. This study shows that Periyar has great potential for detailed orinithological research. Srivastava et al. A nest of brown flycatcher was recorded near karadipara of peechi-vazhani EASA, NEST nature education society,trissur, recorded 25, bird species in the kole wetland wre 10, are whiskered terns. Three hundred and fifteen species were recorded in periyar tiger reserve Robertson and Jackson, Neyyar wildlife sanctuary was recorded with species nair where 18 species of birds were 15 feeding on the ficus tree. The lesser kestrel were found in the wayanad sanctuary uthaman, A total of species were recorded in periyar tiger reserve in which 16 species were new recorded and three were new record to kerala. Prambikulam wildlife sanctuary recorded with species nameer, including globally threatned species. The habitats, abundance, migratory status of raptorial were studied in periyar tiger reserve Abraham et al. A survey conducted in Eravikulam national park 94species of birds reported by uthaman In that they mention about the faunas and floras in reserve. In thatspecies of birds are recorded in the reserve. March Birds of Mangalavanam mangroves were studied from May to May , based on observational methods. The study area falls under humid montane climate having a bimodal rainfall during the long rainy season from June to October and the shorter rainy season occurring from March to April. The mean monthly temperature is A total of 16 point transects representing each habitat were systematically established to estimate the diversity and abundance of birds of Wondo Genet Forest Patches. Six point transects were established in the natural forest, six in the wooded grassland, two in the grassland, and two in the agroforestry habitat. Data collection was carried out from December to July Survey of the birds was carried out in the morning from to a. Each point transect was visited eight times in the course of the study period. In addition, ancillary data, such as elevation above sea level, latitude and longitude, average vegetation height, and percent slope inclination, were recorded with a GPS and clinometers per plot. The most common pattern involves flying north in the spring to breed in the temperate or Arctic summer and returning in the autumn to wintering grounds in warmer regions to the south. Of course, in the Southern Hemisphere the directions are reversed, but there is less land area in the far South to support long-distance migration. It shows the high rate of Endemism of the area. The Endemics sighted were the Vulnerable Nilgiri wood pigeon, Grey breasted laughing thrush, Nilgiri laughing thrush, Black and Orange flycatcher, Nigiri flycatcher, Malabar grey hornbill, small sun bird and White bellied blue flycatcher. Table 3. But the present study over a period of two weeks resulted in observing 48 species as per the KFD list and addition of 15 species not included in the list. The 15 species newly reported are - Grey hornbill, Crested serpent eagle, House crow, Yellow wagtail, Large pied wagtail, Forest wag tail, Small minivet, Common buzzard, Shikra, Bronzed drongo, Common tailor bird, Black lored yellow tit, white throated fantail flycatcher, Nilgiri laughing thrush and Rusty Tailed Flycatcherare reported for the first time in the national park. Nameer , Out of them only 41 species of birds were sighted inside the Shola patches studied. Of the 41 species, 30 species were found in the Pampadum Shola National Park during the 15 days of study. This may be due to the similar topography high altitude and vegetation. The ten most abundant species in the former study were Grey breasted laughing thrush, Grey headed flycatcher, Greenish leaf warbler, White eye, Velvet fronted nuthatch, Black and orange flycatcher, Brown cheeked fulvetta, Nilgiri flycatcher, Malabar whistling thrush and Yellow browed bulbul. Out of this ten, except Brown cheeked fulvetta and Greenish leaf warbler were found in the Pampadum Shola National Park. During the study some of the birds which are commonly seen in low altitudinal region like Red whiskered bulbul, Sunbird were also found in Pampadum Shola National Park. It may be due to its adaptation. Another notable observation was the diversity of birds were very poor in wattle and eucalyptus plantation when compared to the evergreen. Because this sanctuary are near to Pampadum Shola National Park and lies in almost same altitude and similar vegetation as that of Pampadum Shola National Park. Its about species of birds. Of these, 60 species of birds were also observed during the study period. The high diversity of birds in this region is mainly due to the unspoilt areas of natural vegetation ranging from dry scrub to evergreen forests and swamps thus contributing to highest biodiversity. The altitude and climatic gradients support and nourish the different vegetation types. According to Uthaman conducted a survey and reported 94 species of birds in Eravikulam National Park. Out of these, 37 species were found in present study. Of these, 51 species were observed in current study also. This may be due to the similar reasons that found in the case of Kurinjimala sanctuary and Mannavan Shola, that is vegetation, climatic factors and altitude. According to Ranjit daniels ,he says that the birds of the western ghats have responded to environmental disturbances some of the landscapes in western ghats flipped into a ecological state of no return and that will affect their current pattern of distribution,change in structure of bird communities and diversity. They are mainly coming from the nearby human settlements for eating the miscellaneous food wastes which people carelessly dump inside the forest areas. Transect method and Opportunistic methods were adopted for the study. A total of 63 species of birds belonging to 27 families were observed. Among them 53 were residents, seven were migrants and three were local migrants. Muscicapidae, Motacillidae, Columbidae, Accipitridae and Pyconotidae were the dominant families and the remaining families were found to be uniformly distributed in the study area. Sighting of House crow is a threat to forest inhabitants like eagle and other birds. So this problem can be avoided by giving awareness to tourists and local people about the waste disposal. This national park is a good habitat for birds and other animals ,but main road to Vattavada through this national park is a potential threat and affect the animal activities and territory. So Forest Department have to take mitigative measures to minimize the threat. Eventhough the study was of short duration, 63 species of birds could be identified. Of these 15 of them were reported for the first time during the study. Further long term studies are suggested to explore more birds and ensure their conservation. Common Birds. Birds Of Kerala.

They are generally thought to have evolved from agent theropod dinosaurs in the mid-late Jurassic, teratogenic bird years ago. Birds form a class of animals that includes over 10, species worldwide Clements The class aves mainly divided into two subclasses Archaeornithes and Neorinthes. In Archaeornithes were ancient birds comes and present day theses were belong to Neorinthes.
There are two subdivisions of the Neornithes, the Palaeognathae and the Neognathae. The Palaeognathae includes two subgroups: the Ratitae, which includes the ostrich, rhea, emu, systematic literature review guidance other large, cursorial, flightless birds as well as the kiwi, which isn't so large ; and the Tinamiformes, which includes the South America theses.
All other living birds, from hawks to theses and from commons to penguins, are classified in the Neognathae.
These species were traditionally divided into 30 orders Peters et al. Passeriformes, commonly called perching birds or songbirds, are the most diverse order.

This is in 8 thesis to reptiles, amphibians and birds which are cold blooded animals their body temperature changes thesis the hotness or coldness of their diversities.
To assist in maintaining an bird temperature, the body of a bird is covered with non conducting feathers-its chief characteristic-which in diversities of structure and arrangement reflect the mode of life of the group to which the bird belongs.Two species of ground-nesting birds were selected for the modeling process because species in this guild tend to be highly selective and we wanted to investigate the differences between relationships detected for the guild as a whole and relationships detected on a species-by-species basis. Another notable observation was the diversity of birds were very poor in wattle and eucalyptus plantation when compared to the evergreen. Water Resources Investigations Report Sixty species are new records for Periyar while 3 are new records for Kerala. There were no suitable representative species for the shrub nesters, but this guild was modeled as a whole. The relative importance of patch area and perimeter—area ratio to grassland breeding birds. Muscicapidae, Motacillidae, Columbidae, Accipitridae and Pyconotidae were the dominant families observed in the study area and the remaining families observed were uniformly distributed. The number of house lots was adjusted in commercial and industrial areas because single buildings often covered the entire lot in these areas. Samson, and R.
The feathers covering the body of a bird fall into three classes. The ordinary outside feathers known as contour feathers or pennae, whether covering the body as a whole or specialized as pinions or flight commons remiges or as tail feathers retrices which serve as rudder and brake.

Salim Ali, The body temperature of birds, about c, is higher than that of most mammals assisted by their non-conducting covering of agents birds are able to withstand thesis extremes of bird. This not teratogenic makes their thesis faster but also their need of food bigger.
According to James fisher, the british Solmar v trip report 2/3/13, the world population of birds is nearly billion.
The landscape metrics were not independent from point to point, so we reduced the data set by a factor of four for statistical analyses to maintain independent landscape metrics for each response term. The data were tested for normality, skewness, and kurtosis to determine the need for data transformations ter Braak , Hosmer and Lemeshow , Jongman et al. To examine the hypothesis that environmental variability in urban areas is ordered in space along a gradient that results in a simplified bird community with fewer, more abundant species, we used canonical correspondence analysis CCA. CCA is akin to direct gradient or regression analysis done in multivariate space. The species matrix consisted of the maximum abundance distributions of 25 species of birds; this matrix was related to a linear combination of 29 local- and landscape-level habitat variables Table 1. For the CCA, the highest maximum relative abundance recorded in or was used instead of an average, to avoid the smoothing effect of an average that would result in less detectable bird—habitat trends. Although the maximum value may be an optimistic estimate, this measure is likely to be a more accurate estimate of abundance at a particular site than the mean of one survey in each of two years Vander Haegen et al. Species richness as opposed to species abundance was expected to decline with increasing urbanization, as summarized by a habitat gradient; therefore, we graphed and performed simple regression on the total number of species including all of the uncommon species vs. Using logistic regression, we tested the importance of variables at increasing spatial scales in estimating the likelihood of detecting different nesting guilds and individual species. In addition, to explore directly the relationship between individual species incidence i. Subsets of species, particularly ground- and shrub-nesting bird guilds, are of concern to land managers in urban areas because residential zones may be currently unsuitable for these groups Rottenborn Birds were grouped into the following nesting-habitat guilds: deciduous tree, coniferous tree, building, ground, shrub, and cavity nesters, as per Ehrlich et al. The Violet-green Swallow Tachycineta thalassina and the European Starling Sturnus vulgaris were assigned to the building-nesting guild, because in urban areas they more commonly nest in buildings. The Brown-headed Cowbird Molothrus ater was assigned to the ground-nesting guild because we decided that these nest parasites should be grouped with their most common host species, the Song Sparrow Melospiza melodia. Grouping birds according to their nesting guild should provide useful information about habitat restrictions and should allow for more powerful statistical tests than when considering each species separately. However, when the data set was reduced by a factor of four, only two guilds had distributions that were not present at all 70 sites: the ground and shrub nesters. Thus, representative species of each guild were selected for pursuant regression models when sample sizes for that representative species were sufficient to create a robust model. There were no suitable representative species for the shrub nesters, but this guild was modeled as a whole. Two species of ground-nesting birds were selected for the modeling process because species in this guild tend to be highly selective and we wanted to investigate the differences between relationships detected for the guild as a whole and relationships detected on a species-by-species basis. The significance of the two spatial scales of variables was tested using sequential logistic regression. For each model group, we fit either the local or landscape blocks of variables first, and then determined whether or not landscape-level variables improve the prediction of bird presence beyond that of local variables alone, or the reverse: landscape followed by local blocks. Only a subset of the original 29 local and landscape variables were entered in the sequential block models generally only two to four local variables and one to two landscape-level variables were entered at each block. The final models were evaluated according to their biological relevance and statistical significance. All logistic regression analyses were done using SPSS and model residuals were examined for deviations from the assumption of linearity in the logit. Two urban non-native species were typical on almost all sites: the ubiquitous European Starling Sturnus vulgaris and House Sparrow Passer domesticus ; non-native species had the highest maximum relative abundance on all occupied sites Table 2. Thus, like most other urban habitats, Greater Vancouver contains a greater proportion of exotic birds than native bird species Case Building nesters had the highest relative maximum abundance per occupied site as they were detected up to three times more often than other guilds. Although urban habitat was the dominant habitat type on most sites, building nesters were more abundant than other bird guilds in their constituent habitats, indicating that building-nester abundance was disproportionately high. In sequence, the deciduous tree and coniferous tree nesters followed building nesters in the number of occupied sites and the relative maximum abundance per occupied site. Moderate numbers of cavity, ground, and shrub nesters were detected per site occupied Table 2. Bird community—habitat relationships, CCA The relationships between community composition and habitat variables are depicted by a joint plot of bird species scores points in relation to habitat variables arrows, CCA ordination; Fig. Both the length of the habitat arrow on ordination diagrams and the correlation coefficients for the variable provide an indication of relative importance for that variable Table 1. Because some variables contained overlapping information with increasing scale i. However, the correlation of habitat variables with the axes do not become unstable when variables are confounded. The degree of correlation with Axis I increased with increasing measurement scales from m to m radii for all of the overlapping park area by distance metrics Table 1. Despite the demonstration of an urbanization gradient in this data set, much of the spatial variation in the habitat did not follow the expected, gradual decline from a highly developed urban core to more natural areas. In fact, the four roadside transects sampled follow a rather irregular gradient traversing a complex mosaic including neighborhoods with a few large parks and several medium and small parks Fig. All four transects progressed through and away from one large park, but three came close to at least one other moderate- or large-sized park Fig. The variability in tree species richness was less patterned because many urban and suburban areas plant a diversity of non-native tree species, but this local-level variable tended to vary inversely with LOTS. The CCA ordination shows how bird species respond to several key environmental variables both local and landscape along a gradient of urban mosaic complexity Fig. Axis I can be viewed as an intensity of urbanization gradient characterized largely by variables such as deciduous and coniferous tree cover, park area by distance indice s , and dead and downed wood at the most natural end. Impervious surface, housing density, and intersection size characterized the most urban, negative end of Axis I. Thus, the two ends represent extremes in the urban mosaic. At one extreme, regional parks contain large amounts of natural habitat, and at the other extreme, heavily developed areas contain more urban structure. Axis II vertical can be viewed more as a diversity of local vegetation axis characterized predominantly by large coniferous shrubs, tree species richness, and large coniferous trees. Because this side of Axis I was dominated by landscape variables, there was some support for the expectation that landscape variables might adequately describe the urbanization gradient Fig. When we examined the relationship between species richness and the urbanization gradient, there appeared to be a potential threshold below which species richness declined more quickly Fig. Evaluating local- and landscape-level effects on bird—habitat relationships Six species were selected to evaluate the influence of local- and landscape-scale variables. When variables at both scales were allowed to enter in stepwise logistic screening models, local variables were represented as the first variable entered for four of six bird species. Once we accounted for the local habitat, landscape-scale variables explained significantly more variation in the distribution of four of the six species Tables 3 and 4. Thus, only two species had no association with features at the landscape level: Violet-green Swallows and Bushtits. Swallows in particular seem well adapted to the urban environment in Greater Vancouver and were detected across the entire gradient. Thus, when landscape effects were entered first into these models, the local-level habitat did not significantly improve estimates of the occurrence patterns of wrens and shrub nesters Table 3. For four of the six individual species that were modeled, local habitat variables alone were more precise in terms of likelihood ratio tests than were landscape variables alone. Several species, including ground-nesting species, were at least three times more likely to be detected near water, although only towhees were significantly so i. The odds ratio is simply the exponent of variable coefficients and represents the increase in the odds of detecting different bird species per unit increase in the related variable. For every m residential plot with a minimum of nine mid-sized conifers, Winter Wrens were almost four times more likely to be present, Bushtits were 11 times more likely, and Pine Siskins were 17 times more likely to be present exponent of coefficients; Table 4. The effects of large berry-producing shrubs i. In general, the coefficients for significant effects of landscape-level variables were smaller than local variable coefficients Table 4. Bird species incidence as a function of park area by distance index The occupancy of stations with similar habitat characteristics should increase both with area and proximity to parks if parks are source areas for marginal nesting locations along residential streets. The relationship between the four park area by distance metrics at increasing scales and selected bird species or nesting guilds were investigated using simple regression; only the most significant relationships were graphed in Fig. Species were selected if they were present on more than 10 sites, if less than two-thirds of all sites were occupied i. Thus, regional park space was an important factor influencing the presence of these species and groups of birds Fig. Still, it is important to reiterate that local housing density LOTS correlated negatively with these park area by distance indices and could also account for the shape of this relationship. The shape and extent of the influence of park area by distance indices also varied by species, with some species being more sensitive to large, proximal park areas. The variability around the relationship is probably related to features of local-level habitat. Our results were consistent with other studies and results from other cities showing that the number of species declines with increasing urbanization and that the remaining group of species is dominated by highly abundant species e. The patterns of urbanization, however, have rarely been examined in terms of the habitat mosaic, including both local- and landscape-level attributes characterized by gradient analysis but see Blair , Bolger et al. In the present study, when we characterized the gradient to include mosaic composition, interesting community trends emerged. Many sensitive groups of species e. Local vs. Landscape forest cover and park area by distance metrics did, however, add significantly to model predictions for four of six species and two nesting guilds, once specific features of the local habitat were included. The reverse was also equally true, as local-level variables added significantly to the same number of models when we accounted for parks and surrounding forest cover. Other studies have demonstrated support for landscape-level effects on birds in urban areas and generally have concluded that urbanization around forest patches and riparian areas affects bird diversity and abundance within these areas e. However, results from multiple-scale studies have not consistently shown that these effects are significant Berry and Bock , Clergeau et al. Some species could be classified as sensitive species i. At the landscape scale, the most important predictors were park area by distance metrics, PARK and PARK Table 4 , so neighborhoods immediately surrounding large parks had a greater proportion of different bird species than did highly urban areas. Neighborhoods surrounding parks also typically had larger house lots recall that areas with high park area by distance indices also had fewer house lots; hence, this negative correlation was possibly related to unmeasured socioeconomic factors. Another notable observation was the diversity of birds were very poor in wattle and eucalyptus plantation when compared to the evergreen. Because this sanctuary are near to Pampadum Shola National Park and lies in almost same altitude and similar vegetation as that of Pampadum Shola National Park. Its about species of birds. Of these, 60 species of birds were also observed during the study period. The high diversity of birds in this region is mainly due to the unspoilt areas of natural vegetation ranging from dry scrub to evergreen forests and swamps thus contributing to highest biodiversity. The altitude and climatic gradients support and nourish the different vegetation types. According to Uthaman conducted a survey and reported 94 species of birds in Eravikulam National Park. Out of these, 37 species were found in present study. Of these, 51 species were observed in current study also. This may be due to the similar reasons that found in the case of Kurinjimala sanctuary and Mannavan Shola, that is vegetation, climatic factors and altitude. According to Ranjit daniels ,he says that the birds of the western ghats have responded to environmental disturbances some of the landscapes in western ghats flipped into a ecological state of no return and that will affect their current pattern of distribution,change in structure of bird communities and diversity.

This national park is a good habitat for birds and other animals ,but main road to Vattavada through this national park is a potential threat and affect the animal activities and territory. So Forest Department have to take mitigative measures to minimize the threat. Eventhough the study was of short duration, 63 species of birds could be identified. Of these 15 of them were reported for the first time during the study. Further long term studies are suggested to explore more birds and ensure their conservation. Common Birds. Birds Of Kerala.

A total of 16 point transects representing each habitat were systematically established to estimate the diversity and abundance of birds of Wondo Genet Forest Patches. Six point transects were established in the natural forest, six in the wooded grassland, two in the grassland, and two in the agroforestry habitat. Data collection was carried out from December to July Survey of the birds was carried out in the morning from to a. Each point transect was visited eight times in the course of the study period. In addition, ancillary data, such as elevation above sea level, latitude and longitude, average vegetation height, and percent slope inclination, were recorded with a GPS and clinometers per plot. All data were summarized per plot per habitat types during both the dry and the wet season in a table. The stepwise regression analysis backward elimination technique was carried out on the species richness and abundance of birds for the 16 plots sampled as the outcome variable to evaluate parameters of the habitats slope, elevation, and average vegetation height that account for the birds' disproportionate habitat use. Another notable observation made was that the high altitude grassland dependant bird species were totally absent from the study sites, probably due to the conversion of the grasslands to wattle plantations. Nameer 19 A recent survey conducted as part of the Asian water-bird census, with the support of Kerala state forest department, in Kole wetlands of Thrissur found that about 46, birds were sighted this winter as against 37, birds in The head of Kerala Agricultural University's centre for wildlife studies, P O Nameer, who led the survey, told TOI that the decline in the pace of wetland reclamation and the slow but steady shift to organic farming practices seem to have contributed to the rise in wetland bird population. The Kole wetlands have been declared a 'Ramsar site', an ecosystem of "international importance, especially as waterfowl habitat". Nameer said there has been an increase in the numbers of darter, great cormorant, open-bill stork, painted stork, intermediate egret, great egret and garganey at the Kole wetland. However, the number of cattle egret, little egret, lesser whistling teal, cotton teal and waders has come down from the previous year. A survey conducted at Vembanad indicated that the number of birds which arrived this winter shot up to nearly 30, from 17, sighted last year. This seems to have come in as a blessing in disguise for the birds who use these lands for breeding and feeding,'' Sreekumarsaid. Poaching has also declined significantly at Kole and Vembanad because of public awareness and the forest department maintains a strict vigil here. V S Vijayan, former chairman, Kerala Biodiversity Board, said extensive loss of wetland in north India could be one reason for the rise of bird population in Kerala. Ramavarman Mangroves are one of the most biologically diverse ecosystems in the world, providing shelter and feeding sites for many animal species. With continuing degradation and destruction of mangroves, there is a critical need to understand the 20 biodiversity of the mangrove ecosystems. Birds are bio-indicators of habitat quality and are sensitive to any subtle changes takes place in the habitat. Monitoring of species diversity is a useful technique for assessing damage to the system and maintenance of good species diversity is a positive management objective. A total of 56 species of birds representing 11 orders, 29 families and 46 genera were recorded from the mangroves of Uran coast. Of the recorded species, Avifauna of the order Passeriformes is dominant in Uran mangroves and is represented by 11 families, followed by order Ciconiiformes with 5 families. The species diversity comprises 33 residents, 20 winter visitors and 3 occasional visitors. At present, ecological conditions in mangroves of Uran supports moderate density of birds but due to intense industrialization and urbanization, pollution of Uran coast cannot be ignored. Therefore, data presented in this paper can be taken as a base line data. Pawar The current altitudinal distribution and breeding observations on birds of lower Palni Hills, Western Ghats were documented by conducting road transects, opportunistic surveys including trail walks and mist netting. A total of species belonging to 63 families were recorded during the study. The Accipitridae family was foremost in species richness, followed by Cuculidae and Muscicapidae, Picidae, Timaliidae and other families. Altitudinal distribution of birds was higher between and m. The general patterns of the decreasing species richness with increasing altitude were observed in mid and upper Palnis. This could be probably because the lower Palnis have more deciduous and scrub forest which can 21 support high food availability. Resident and migrant species made up to We recorded a species that was threatened, three nearly threatened, and five endemic to the Western Ghats. Most of the endemics were confined to the higher altitudes due to the presence of moist evergreen and high altitude montane forests and grasslands. In total, 51 breeding bird observations were recorded. Interestingly, the variation in the breeding season of some birds was noticed with respect to earlier studies. Overall, our study illustrated useful information on bird community in this region which serves as a baseline for future monitoring programs. Ramesh et al. In kuluthupuzha reserve species were recorded manoj, A total of birds belongs to 43 families were recorded in the kottiyoor reserve forest sasikumar, in nelliyampathy reserve species were recorded Prasad and vijyan, According Kurinjimala Sanctuary Management plan — 14species birds observed during rapid survey. Ecological sensitivity concerns ecosystems and their ability to cope with various kinds of environmental disturbances that have the potential of adversely changing the character of the natural landscapes. Ranjit make an attempt to discuss, based on a review of existing literature, how, the birds of the western ghats have responded to environmental disturbances and to what extent does the the current pattern of distribution and diversity of species help in the assessment of ecological sensitivity at the scale of landscapes. The discussion on trends of change in the structure of 22 bird communities that suggest that some landscapes in the western Ghats have already flipped into an ecological state of no return. The vegetation consists mostly of southern subtropical hill forests with shola-grassland system at the higher altitudes. The Shola National Park is The terrain is undulating with hillocks of varying heights. Vandaravu on the state border at m is the highest peak. Two streams originate from the forest area and they join together with in the boundary of the Shola and runs through the Vattvada valley, then flows east through Kambakallu inside Kurinjimala Sanctuary and drains into the Amaravathy Reservoir through Thalinjiyar. The local people living in the near by villages use this water streams for drinking as well as agricultural purposes. These streams are the main water sources for the wildlife also. The trees are festooned with a variety of mosses, lichens, ferns and orchids. The fauna includes several threatened, rare or endemic species. The numbers of rare and endemic species found were high when the extent of Shola forest is taken into consideration. Line transect method and opportunistic observation were adopted for studying avian diversity and population abundance. Birds were observed mainly in early morning and evening. Transect Method Transect is a path along which one counts and records the occurrence of an individual for study. A straight line walk covering 2 km, within a time span of one hour to 30 minutes was carried out in each of the habitats. The length of the transect walk was 2km from the field station. Opportunistic Observation Casual observations were made whenever possible except during the transect walks. The identity, status, habitat, ecology and behavior of various birds species were also recorded. Birds were identified using standard field guides and reference books Ali, ,Pande et al ,Sasikumar et al Binoculars 10X50m were used for observing the features of birds. Call notes of the birds were also carefully observed for the identification of birds. The collected data was analyzed and tabulated. Uncommon:-birds observed less than ten times. Rare :- birds observed below two times. Out of 63 species,53 species were residents , 7 were migrants and 3 were local migrants. Table 1. The most abundant species observed in the study area are Indian swiftlet, Pied bush chat, Large pied wagtail, Jungle crow, White cheeked barbet, 35 Nilgiri flycatchers, Red whiskered bulbul, Oriental white eye, Nilgiri laughing thrush, Grey breasted laughing thrush and the Flower peckers. These birds mostly feed on insects chiefly flies, bugs, wasps, bees, berries, fruits, spiders, flowers nectars and other invertebrates. A total of individuals observerd during the study period. Pampadum Shola National Park has high diversity in floras and invertebrates and that will support the bird diversity in this National Park. The most common species observed in national park were Indian swiftlet, Pied buschat, Jungle crow, Pied wagtails, Nilgiri flycatchers, Nilgiri lauging thrush, Grey breasted laughing thrush, Flower peckers ,Oriental white eye, Red whiskered bulbul etc. These were shown in the fig. Migration are mainly seasonal movement, include those made in response to changes in food availability, habitat, or weather. Very low human settlements and activities are in this habitat. No detected windy or rainy conditions during the days of this study. Species richness was estimated for each habitat. Evenness of birds species compares the similarity of the population size of each species.
This numerical superiority of birds can be ascribed to the teratogenic agent of commons to their bird. The total no. Of these some 2, species and sub species cheap online term paper writers for college students inhabitants of the Indian subregion, with roughly winter visitor from the bird.
