Opis:
This study focused on bird species richness and diversity in Borgu sector, Kainji Lake National Park, Nigeria. The study was undertaken to derive information on the species of birds utilizing the study area, and to determine the relative abundance and diversity of birds in the study area. The Line transect methods was used for the study. The result revealed that the present number and kinds of birds species in all the ranges sampled is very low, with Range 4 having the highest bird’s species richness of (22.29%). A total of 3255 birds were inventoried in all the ranges. These belonged to 44 species from 28 families. Family Ardeidae contain the highest number of 593 birds, followed by the family Sturnidae and Numididae - having 392 and 351 birds, respectively. The findings indicate that birds’ abundance is very low with many bird species displaying 0% relative abundance. The low abundance and diversity of birds indicates that Kainji Lake National Park birds in relation to habitat characteristics is very poor. Furthermore, the result from the test prediction Output shows that the estimators predict that (after 5 samples) there will be 41 birds’ family species in the habitat in future, since they (ACE, ICE, Chao2, Jack2) level off at 41. The result indicate that only the same birds species, instead of new birds species are presently seen in Kainji Lake National Park, which are poorly represented among 28 families sampled. It is, therefore, recommended that environmental education campaign on birds’ conservation and protection should be carried out in the communities around the park so as to persuade residents to stop killing birds.

Opis:
Avifauna are important for the ecosystem as they play various roles as scavengers, pollinators, seed dispersal agents and predators of insect pest and an important indicator to evaluate different habitats both qualitatively and quantitatively. A study was conducted during February 2012 to February 2015 in Chinsurah, the district town of Hooghly, West Bengal, India. This study was done in ix different habitats present in the core region of the town. These are agricultural land, river bank, small woody area, small water body, grassland and human habitat. A total of 67 avian species were recorded during this study. These species show preferences to various habitats, where some are specialist to one of the habitats and some are generalist to different habitats. Abundance of birds in different habitats is different, most probably due to the variation in amounts of resources in these habitats. Due to loss of natural habitats habitat specialists are gradually replaced by habitat generalists.

Opis:
Birds are found in a variety of habitats, performing various functions. They are highly sensitive to even minor perturbation in ecosystems. Documentation of avian assemblages in different ecosystems is, therefore, becoming increasingly important from environmental monitoring perspective. In absence of comprehensive account of birds of Bibhutibhushan Wildlife Sanctuary, West Bengal, India, we made an attempt to document the birds thriving in this protected area. A total of 102 species of birds belonging to 13 orders and 46 families were recorded during the study period (June 2013 – May 2016). Maximum number of species belong to the order Passeriformes (49 species) and minimum under order Anseriformes (1 species). Among the total bird species, 83 species (81.37%) were resident, 15 species (14.71%) were winter visitor, three species (2.94%) were summer visitor and one species (0.98%) was passage migrant. We noted 38 species of birds (including 36 residents and two summer visitors) to breed within the sanctuary. Analysis of feeding guild data revealed that 46.08% were insectivore, 22.55% were carnivore, 15.69% were omnivore, 6.86% were granivore, 5.88% were frugivore, 1.96% were nectarivore and 0.98% were herbivore. Grey-headed Fish Eagle (Icthyophaga ichthyaetus) and Red-breasted Parakeet (Psittacula alexandri) are two Near Threatened (NT) species designated by IUCN. Present study is the first scientific documentation of avian assemblage of this protected area and will serve as a baseline data for future avifaunal research, as well as, will be useful in the preparation of Peoples’ Biodiversity Register (PBR) of this area.

Opis:
Observing wildlife at their natural habitat is practically a chance factor. However, there is alternative way by which it is possible to study the presence of wildlife and also their activities by indirect methods. North Bengal, especially Dooars is extreme rich in wildlife; therefore, there are many National Parks, Reserve forest as well as Wildlife Sanctuaries at this terrain. Studies on presence of wildlife by means of indirect evidences from different National Parks of Dooars reveals many untold stories. From this study it also evident that Dooars region is still harboring very good verities of wildlife, therefore, this is the demand of time to conserve these forests, as well as wildlife not only to save them from quick destruction but also to maintain human civilization.
