306 BIRDS OF THE REPUBLIC OF PANAMA PART 3 



land on the shore of Bahia Almirante. Here they moved about freely, 

 paying little attention to me. On my first encounter with them here, 

 at least 20 were seen within a distance of less than a kilometer. On 

 Isla Cebaco a number lived on a wooded hill, moving about from 

 near the beach to an elevation of 200 meters. Here they were feeding 

 on dark-colored drupes, which made an inklike stain in the body 

 cavity of those prepared for specimens. 



Older accounts list specimens taken by Arce from Cordillera de 

 Tole, Chiriqui ; Calobre and Calovevora, Veraguas. Griscom re- 

 corded them as common on Cerro Flores, eastern Chiriqui, in 1924. 



In 1962 Dr. Charles Handley, Jr., found them on the summit of 

 Cerro Hoya at the southern end of the Azuero Peninsula in Los 

 Santos, the most eastern point at which they are known. In my own 

 work in the field, in addition to the localities mentioned, I noted the 

 species also in the forest at Aguacaton in the upper end of the Burica 

 Peninsula. Whether in Panama they shift after the nesting season 

 from colder, higher elevations in the mountains to lowland areas, as 

 they are reported to do in Costa Rica, is uncertain from present data. 



Ridgway in his outline of records of occurrence (U.S. Nat. Mus. 

 Bull. 50, pt. 4, 1907, p. 883) listed one from "20 miles from City 

 of Panama," quoting the locality from the data on the label of a male. 

 The bird came to the National Museum in a small collection purchased 

 in May 1887 in Panama City. From its appearance it was one pre- 

 pared by Arce and without question was taken in western Panama. 



Though the bird, called calandrm, is widely known, I found no 

 one with knowledge of its nesting. 



The species ranges beyond Panama north through Honduras.
