Abstract:

Robust environmental data is a prerequisite to curtailing the current environmental degradation. Understanding species-habitat interactions and species’ response to habitat and seasonal changes is necessary, considering the degradation in the quality and quantity of native habitats. Moreover, assessing the interaction between birds and their habitats is essential in regions like Kano, Nigeria that are subjected to extensive land degradation. During this study, the avian species composition and seasonal variation in abundance and richness in four habitats (farmland, shrubland, wetland, and suburban) were assessed. The line transect sampling method was used to count birds across the wet and dry seasons from 2018 to 2019. Species richness and abundance varied considerably across seasons and habitats. Species abundance was highest in the wetland, while the shrubland had the highest species richness. Environmental factors had significant effects on species abundance and richness.  The results indicated that habitat is more important in predicting species composition than season, and there was significant interaction between habitat and season in explaining species abundance and richness. This study highlights the significance of the shrubland and wetland as hotspots for avian biodiversity. Therefore, there is need to prioritise these sites in the course of conservation action by the concerned authority.
