Bird diversity and breeding status at Nakol Union under Magura District of Bangladesh

Nakol Union of Bangladesh could be a better green place to observe avian population. Descriptive analysis and correlation helped to mention the present status of avian diversity and breeding patterns at Nakol Union, based on data from 14 avian orders comprising 35 families and 61 species. Results revealed strong positive correlations between the number of families, species, and breeding species (r > 0.95). This indicates that higher taxonomic diversity is directly associated with greater breeding richness. Overall findings highlighted that conservation strategies should prioritize diverse avian orders such as Passeriformes and Columbiformes, which contribute significantly to local breeding populations. Out of 61 species of birds, passerine birds were 44% and non-passerine 56% as well. Within all species, orders were 14, families 35, and breeding birds 20. Remarkable plants were banyan (Ficus benghalensis), rubber (Ficus elastica), American mahogany (Swietenia mahagoni), coconut (Cocos nucifera), karoi (Albizia procera), and some village ponds supported to build their nest for successful breeding. Resident birds were counted 56, summer visitor 1, winter visitor 2, rare 2, and few 10 species. Based on availability of the birds, this union focused very common birds 26, common 21, and uncommon 2. This study was carried out from July 2024 to June 2025 at Nakol village.
