Drongo (fingey) medium-sized songbirds, with glossy black plumage, long pointed wings, slightly hooked stout bills ornamented with long bristles about the mouth, and very long forked tail. They belong to family Corvidae, order Passeriformes, and live in the wooded country of Africa, the Orient and Australia. The family is best represented in southern Asia.
Drongos are aggressive arboreal birds and often drive off birds much larger than themselves. They have wide vocal repertoire; typical calls include metallic notes, modulated whistles, and harsh scolding notes; few have complex and attractive songs. They are primarily insectivorous, and feed mostly on large flying insects. However, they occasionally feed on small vertebrates. Worldwide there are about 24 species of drongos; Bangladesh has six.
These are Bronzed Drongo (Dicrurus aeneus), Crow-billed Drongo (Dicrurus annectans), Spangled Drongo (Dicrurus holientottus), Black Drongo (Dicrurus macrocercus), Greater Racket-tailed Drongo (Dicrurus paradiseus) and Lesser Racket-tailed Drongo (Dicrurus remifer). Sexes of all these species are mostly similar. [Md Anwarul Islam]
