SEPT., 1910. BIRDS FROM COSTA RICA FERRY. 261 



Columbictae. 



Columba flavirostris Wagl. 



3 specimens. Guayabo cT. These birds were abundant about 

 the potrero, where they resorted to dead branches of the tallest trees 

 during the sunny mornings. At such time their loud cooing could 

 be heard anywhere. They roost in the heavy foliage of tall trees. 

 They feed upon wild fruits, their crops being frequently distended 

 with large, succulent berries. (Native name " Berengena.") 

 They are rather shy birds and are known among the natives as 

 " Paloma," the common name for pigeon. 



Columba albilinea crissalis Salv. 



4 specimens. Vol. de Turrialba cr. These birds were abundant 

 in the open forest about the lecheria. What impresses the stranger 

 most is the exceedingly loud flapping of their wings, just as they launch 

 into flight. They have a habit of remaining perfectly quiet, well 

 hidden in the foliage, and fly only when the hunter is beneath the 

 tree. This sudden, loud wing-beating is then often quite startling. 



Columba nigrirostris Scl. 



i specimen. Guayabo cT. Apparently much rarer than C. flaviros- 

 tris with which it was associated. 



CuculidaB. 



Piaya cay ana thermophila (Scl.). 



4 specimens. Guayabo icT, 2 9 ; Coliblanco id 1 . 



This bird was common at Guayabo, where it resorted to the 

 dense shrubbery. Its habit of running along branches like a squirrel 

 was observed several times. It effects its escape in this way fre- 

 quently. When alarmed, though, the bird usually seeks safety by 

 remaining perfectly quiet. At Coliblanco the birds were observed 

 several times in the tops of high trees. 



Crotophaga sulcirostris Swains. 



10 specimens. Guayabo 36^, 4$; Coliblanco i$; Turrialba 

 Station 2 9 .
