 \vith this beautiful Falcon for the first time on the Savannas in tlie 

 vicinity of Pirara. Its favourite haunts are solitary o-rowino: 

 Curatella trees, also bushes, from which it soars up into the air 

 for some time, returnino- to the same tree or bush. It prevs on 

 small birds and amphibia. The *' Macusis""' and the " Arekunas '' 

 call it Sakuta. 



Mr. J. J. Huelch remarks on this species as follows (Timehri 

 (2) vi. p. 12y) : — " The Slate-backed Hobby (Hypotriorckis 

 femoralis) is somewhat common on the coast, being obtained 

 about the estates and along the creeks. It is, however, widely 

 distributed over the Colony. It is a bold and fierce bird, and, 

 owing to its long wings and tail, is characterized by a rapid and 

 even sailing flight."
