50 FALCONID^. 



In Guatemala it is equally common, and we found it as high as 5000 feet at Duenas, 

 and at 4300 feet at Coban, as well as in many intermediate localities to the sea-level. In 

 Costa Kica it would appear to be less abundant, but its name is included in Zeledon's 

 lists; and Mr. Cherrie states^ that there is a specimen in the museum at San Jose. 

 Arce sent us specimens from Chiriqui, and thexe is an example in the British Museum 

 obtained through Boucard from Panama. This is the most southern locality recorded 

 for this Sparrow-Hawk, for in South America it has not yet been detected. 



The name by which this species used to be known is Accipiter fuscus, the Falco 

 fuscus of Gmelin, a title of very doubtful application, and now discarded by American 

 writers in favour of Accipiter velox -of Wilson, concerning which there can be no 

 uncertainty. 



The habits of this bird are fully described by Capt. Bendire ^ and Dr. Fisher ^, the 

 latter author -giving a tabular statement of the food of 15.9 individuals, showing it to 

 consist, to a very large extent, of small birds of nearly fifty ascertained kinds, ranging in 

 size from Warblers to Pigeons and Quails. Mice also are very occasionally consumed.

Accipiter chionogaster is a northern representative of the South- American A. erythro- 

 cnemis, with which it was at one time confused. The latter bird has the feathers 

 of the tibiaj deep rufous and the under surface more or less barred ; whereas in the 

 former the tibiae are pale rustj-red, and the under surface at jnost, shows narrow dark 

 shaft-stripes, and no trace of cross-bars. 



The northern range of this species does not extend beyond Guatemala, where,
