Jerdon's baza (''Aviceda jerdoni'') is a moderate sized brown hawk with a thin white-tipped black crest usually held erect.〔 It is found in South-east Asia. It inhabits foothills in the terai and is rarer in evergreen forests and tea estates.〔Rasmussen, PC & Anderton JC 2005. ''Birds of South Asia. The Ripley Guide.'' Vols. 1 and 2. Smithsonian Institution and Lynx Edicions, Washington, D.C. and Barcelona〕 The common name and Latin binomial commemorate the surgeon-naturalist Thomas C. Jerdon. ==Description== It is about 46 cm long. It is confusable with crested goshawk or the crested hawk-eagle in flight, but can be distinguished by the longer upright crest, very broad and rounded paddle-shaped wings〔 and mostly plain and pale underparts. It has a white chin and a bold black mesial stripe.〔Ali, S & Ripley, SD 1983. ''Handbook of the Birds of India and Pakistan.''Compact edition. Oxford University Press.
