high overhead, or rose, at times, from his feast on some putre- 

 scent matter by the waterside." 



Mr. Quelch also observed it at Georgetown (Timehri (2) v. 

 p. 103), and writes : — " Yerr frequently also, but seldom more 

 than one at a time, the Red-headed Carrion Crow or Turkev- 

 Buzzard {Cathartis aura.) may be met with, The>e are much 

 larger birds^ about thirty inches in length, and are often referred 

 to as Governor Bird, and King or Governor of the Carrion 

 Crows.^^ 



On p. 104 he farther remarks: — "It seems to me doubtful 

 whether the Yellow-headed Yulture (C. perniam), which is also 

 occasiouallv seen, is specifically distinct from this form, even 

 though its plumage is blacker and the shafts of the quills brown 

 above.'' 



Mr. Quelch also remarks on the food of this bird (Timehri 

 (2) vi. p. 120) : — ''Masses of leaves were discovered in the body 

 of some of the specimens of the Ked-headed Yulture (CatJtartes 

 aura). Scarcity of Carrion Crows would be sufficient to explain 

 the peculiarity in the case of the Yulture. though even then one 

 would huA-e ima^iined that fresh flosh would have been more 

 acceptable than leaves.""
