CNP provides major habitats for the feeding and breeding of a large number of migratory birds from many parts of the globe and also plays a vital role in the conservation of threatened species. We recorded a total of 437 individuals of globally threatened birds belonging to 19 species of nine families and eight orders. There was considerable variation (F=2.94, df=44.43, p=0.05) in species diversity of threatened birds in different study blocks: the highest diversity was in Block E (Pithauli, Amaltari, and Narayani Island area; H=2.108), followed by Block C (Kasara to Sukibhar area; H=2.047), Block B (Barandabhar Corridor Forest; H=2.033), Block A (Khagendra Malli, Kathar, Sauraha to Old Padampur; H=1.744), and Block D with the least diversity (Madi area; H=1.69). The higher dominance index was found in blocks A (D=0.2407) and D (0.2361)
