This study focused on the bird’s species richness and diversity in Okomu National Park, Nigeria. The studies was undertaken to derive information on the species of birds utilizing the Okomu National Park as well as determine the relative abundance and diversity of birds in area. The methodology employed in the study includes the use of direct method of census. Line transects was used. The data collected were analyzed using descriptive statistics (tables). The result gathered revealed that the national park is rich in birds species. A total number of 706 birds’ species in 23 families were also inventoried in all the ranges. The highest families Accipitridae, Alcedinidae, Bucerotidae, Muscicapidae, and Ploceidae has 3 represented species each, followed by families Meropidae, Nectariniidae, Picidae and Sturnidae having 2 represented species each. Birds were found in all the selected habitats. The park areas are under constant threat from unsustainable poaching, logging practices, and land conversion to agricultural uses. This logging and land use change have impacted Okomu National Park forests and the forest ability to withstand the effect or to become 'resilient' might be difficult due to the effects of climate change, and deforestation. Therefore there is need to include both the local indigenes and staff who knows the park area boundaries very well to be involved in the protection of the park resources. This will help in discouraging the killings of bird’s species by local poachers and others.

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.

Ecopark Kolkata is a protected urban park of Kolkata West Bengal, having an area of approximately 480 acres. The study was conducted from May 2020 to April 2022. This study provides baseline data of moths in Ecopark, Kolkata. This is the first documentation and evaluation of the role of moths in the food web maintenance in birds, specially focused on an urban park in Kolkata. A total of 37 species under 12 families were reported in this present Survey. Of these, Crambidae shares maximum species 12 followed by Erebidae with 9 species; Noctuidae with 4 species; Zygaenidae, Sphingidae, Pyralidae each with 2 species and Uraniidae, Pterophoridae, Euteliidae, Geometridae, Nolidae, Limacodidae each with 1 species. The maximum number of the caterpillars of moth was found on Crotalaria retusa, Hymenocallis littoralis, Hiptage benghalensis, Ziziphus ziziphus, Moringa oleifera, Pithecellobium dulce, Lantana camara etc. Preference of food in between the resident birds also were found to be variable based on the bird species and the life stage of the moth and that in an urban park where vegetation and associated diversity is limited, moths can serve as a good supplementary food source for birds.
