The fine series of specimens of this Hawk collected by 

 Mr. Shortridge shews all the stages of plumage from the 

 immature to the adult. There can be no doubt that 

 H. orientalis (Schl.) [Sbarpe, Cat. Birds B. M. i. p. 422 

 (1874)], was founded on immature or dark-coloured examples 

 of the present species. The plumage of some of the speci- 

 mens in the above-mentioned series is somewhat puzzling, 

 for there are birds with the breast, flanks, and thighs dark 

 brown, which appear to have reached maturity. It seems 

 probable that this species is more or less dimorphic, and that 

 the light and dark brown phases of plumage are due to this 

 cause and not to age, though it must be remembered that 

 all young birds have the under parts dark brown. 



[The Berigora Hawk was very abundant and widely dis- 

 tributed. It was the most plentiful bird of prey in the south- 

 western and southern districts. — G. C. £.]
