from the outside. It had not been in use for some weeks, so the 

 birds were not in the habit of finding food there, and it seems 

 most probable that they had been guided to the spot by the 

 slight sense of smell which these birds seem able to exercise 

 at short distances. 



Cathartes aura aura (Linn.). North American Turkey 



Vulture. 



It is curious to note that while the Black Vultures are of 

 the South American form, the Turkey Vultures belong to the 

 same subspecies as those of North America. They are not 

 abundant in Costa Rica, more than a pair seldom being seen at 

 one time. They rarely stay about slaughter houses and siniilar 

 places after the habit of the Blacks, but are usually seen alone, 

 prowling about the potreros.... They were shy and seemed to be 

 in fear of the Blacks, perhaps because of the superior numbers 

 of the latter. 



Nyctidromus albicollis albicollis (Gmel.). CuiEJO. 



This is the only common Goat Sucker about Guapiles. In 

 the daytime, specimens were frequently disturbed as they sat 

 on or near the ground, and at night their calls resounded from 

 all sides. 



On April 19th, three nests of this species were discovered 

 in some open brush along an abandoned tramway. Two were 

 about twenty-five feet apart and the other about one hundred 

 feet distant. Each contained two pale brownish eggs, blotched 

 with chocolate; all were fresh. One set was deposited in the 

 hollow of a great, dried leaf; another between several smaller 

 leaves and the third on the ground beside a large stone. No 

 other nests were found during the entire trip and as there ap- 

 peared to be nothing to distinguish this particular locality from 

 the surrounding country, their occurrence there seems a curious 

 coincidence. 



Chrysotrogon caligatus (Gould). Gartered Trogon. 



This is the most abundant Trogon about Guapiles. It is 

 met with in the bits of bush along streams and in the pastures
