424 BIRDS OF THE REPUBLIC OF PANAMA PART 3 



pass on southward, they are common through the winter as I have 

 recorded them regularly from late December through March and 

 April. Late records in spring include one at Fort Davis, Canal Zone, 

 May 11, 1961 (Eisenmann) and one on May 25, 1961, at Barro 

 Colorado by Willis (Living Bird, 1966, p. 192). Eisenmann recorded 

 one at 700 meters near our quarters at Buena Vista, Chiriqui, March 

 4, 1960; Ridgely found one near Boquete, Chiriqui, November 9 to 

 11, 1968; Goldman collected one at 550 meters at Cana, Darien, 

 February 28, 1912. 



In general they are restricted to the mainland, though on Isla 

 Coiba I collected one January 19, 1956. Elsewhere in the Gulf of 

 Chiriqui I recorded one March 23. 1962, on Isla Brincanco, in the 

 Contreras group, and several on Isla Parida February 2 to 7, 1963. 

 Others were recorded on Isla Gobernadora January 8 to 10, and 

 Isla Cebaco, January 15, in the Gulf of Montijo. The only record 

 for the Perlas Islands is of two taken on Isla Saboga April 9 and 13, 

 1904, by W. W. Brown, Jr. While several may be seen during a day, 

 they range singly, or two or three near one another. A majority of 

 the records in my own notes are of birds heard calling from forest 

 cover. 



A major part of their food in their winter quarters in Panama 

 is the small fruits of berry-bearing trees. They visit such trees 

 regularly in company with the resident tropical birds that seek this 

 supply. Eisenmann reports them feeding on the berries of mistletoe, 

 and of uvero, Hamelia nodosa of the Madder family. In addition I 

 have found large orthoptera and other insects in the stomachs of 

 those I have collected.
