50 FALCONIDA. 
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 Rica 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 José. 
Arcé sent us specimens from Chiriqui, and there 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 9, the 
latter author giving a tabular statement of the food of 159 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 J. erythro- 
enemis, with which it was at one time confused. ‘The latter bird has the feathers 
of the tibia deep rufous and the under surface more or less barred ; whereas in the 
former the tibie are pale rusty-red, and the under surface at most, shows narrow dark 
shaft-stripes, and no trace of cross-bars. 
The northern range of this species does not extend beyond Guatemala, where,
