This is a very abundant species over the whole republic of 

 Guatemala; but at Duenas it is migratory, being a visitant there 

 only during the winter months. The name applied to this 

 species by the Spaniards is ' Klis-klis.'

 from Honduras. Mr. Leyland met with it in the S. Pedro

290. RosTRHAMUs sociABiLis (Vicill.). 



Salvin ascribes the immense flights of hawks seen by him in 

 the month of March in the Pacific coast-region, migrating in a 

 north-westerly direction, to this species. The bird is well known 

 to the Spaniards under the name of the 'Asacuani-/ and the 

 term has become proverbial for a person who is constantly wan- 

 dering from place to place. Mr. Leyland procured a single 

 specimen of this bird near the Lake of Peten.
