crested goshawk
The crested goshawk (''Accipiter trivirgatus'') is a bird of prey from tropical Asia. It is related to other diurnal raptors such as eagles, buzzards (or buteos) and harriers, and thus placed in the family Accipitridae.〔Grimmett ''et al.'' (1999)〕
==Description==
This raptor has short broad wings and a long tail, both adaptations to manoeuvring through trees. It is 30–46 cm in length, with the female much larger than the male. The larger size and a short crest, clearly visible in profile, are the best distinctions from its relative, the besra (''A. virgatus'').〔
The male has a dark brown crown, grey head sides and black moustachial and throat stripes. The pale underparts are patterned with rufous streaks on the breast and bars on the belly. The larger female has a browner head and brown underpart streaks and bars. The juvenile has pale fringes to its head feathers, and the underpart background colour is buff rather than white.〔
The flight is a characteristic "slow flap, slow flap, straight glide", similar to other ''Accipiter'' species such as the northern goshawk (''A. gentilis'').〔
