214. Herpetotheies cachiniians (liiiiii.)- 



Common on the Escondido. The j^uttuial laugh which usually pre- 

 cedes the lougcall of this species can be heard only a short distauce. 

 The bi'.dscall most frequently about dusk, and kee]) it up until after 

 dark. The first individual I saw was in a large dead tree on the Rio 

 Frio, near where T was encamped for the night. Tt began its monot- 

 onous call about dark and continued it for fully fifteen minutes. It is 

 often called ^-EaiuCrow" by the x\mericans on the Escondido. 



Iris burnt uml)er. 



215. Elanoides foificatus (Linn.). 



A small company noticed circling about on the Escondido on May 15. 



216. Circus hudsouius (Linn.). 



Connnon during the winter on the Escondido. 1 shot one October 

 2, in the act of carrying off a chicken. In Nicaragua it never lets an 

 opportunity pass to get a chicken, probably because it fails to secure 

 enough food in other ways, as the conditions are totally different from 

 those prevailing in its hunting grounds in the United States. Small 

 mammals appear to enter very little into the food of the birds of ])rey 

 there, owing to the dense vegetation and the difficulty of se(;uring them, 

 but lizards, snakes, and insects are much sought foi'. 



217. Accipiter velox (Wils.). 



Found by Wickhiun on the Escondido; 1 did not meet with it. 



218. Urubitinga anthracina (Ijiclit.). 



219. Urubitinga urubitinga ridgwayi (Gnrney). 



Not very common. Found usually in ])airs. The above t-wo species 

 were observed on the Escondido, wher<' Wickham secured sj)ecimens. 

 Also noted at San Carlos. 



220. Leucopternis ghiesbreghti (DnBns). 



Mr. G. E. Mitchell got one specimen in the forest on the Escondido.* 

 A Hawk that may be Lcucopfeniis plumhcus Salv. was often noticed 

 on the Rio Fri >. It was usually found i)erched on limbs over the water, 

 and was very tame, allowing the dory to pass under it at a distance of 

 less than 10 feet, in some cases. One was observed to catch a large 

 green lizard. Unfortunately no specimens Avere preserved, and the 

 identification must remain in doubt. 



221. Rupornis ruficauda (Scl. and Salv.). 



This is the most abundant Hawk on the Escondido. It is found in 

 the plantations and cleared places, usually in pairs. 



Iris noted as yellow, and in some specimens as light brown, the 

 latter probablj^ immature birds ; cere yellow.
