Abstract

Robust environmental data are a prerequisite to curtailing the current environmental degradation, and understanding species-habitat interactions as well as species’ response to habitat and seasonal changes is necessary with degradation in the quality and quantity of native habitats. Moreover, assessing the interaction between birds and their habitats is essential in Afrotropical regions like Nigeria that are subjected to extensive land use degradation. Here, we explored avian species composition in four habitat types (farmland, shrubland, wetland, suburban) and also evaluated their seasonal variation in community composition. We carried out bird count using line transect sampling method over six seasons. Species richness and abundance varied considerably across seasons and habitats, bird assemblages were also distinct between habitats and seasons. Seasonal change in community composition was observed across habitats over the sampling seasons, which was more evident in the shrubland and farmland. Species abundance was highest in the wetland, while the shrubland had the highest species richness, and in particularly, these two habitats had the largest number of Palearctic migrant species. The European Turtle Dove (Streptopelia turtur), and Pallid Harrier (Circus macrourus) are the species of conservation concern recorded. This study highlights the significance of the shrubland and wetland as hot spots for avian biodiversity; we therefore call for the prioritization of these sites in the course of conservation action by the concerned authority.
