FAMILY COEREBIDAE

the maxilla reddish brown; opercula and basal half of mandible light 

 wood brown; rest of bill dull black; tarsus and toes Verona brown; 

 claws mouse brown. A female taken at the head of the Rio Guabal, 

 Code, on March 2, 1962, had the iris reddish brown; maxilla and tip 

 of mandible fuscous-black; base of mandible dull brown; gape dull red; 

 tarsus and toes warm brown; claws black. 



Measurements. — Males (10 from Panama), wing 61.6-66.0 (63.5), 

 tail 37.6-43.3 (41.4), culmen from base 12.5-14.7 (13.7), tarsus 14.4- 

 16.8 (15.8) mm. 



Females (10 from Panama), wing 58.0-62.7 (60.7), tail 38.6-42.3 

 (40.8), culmen from base 13.1-14.4 (13.9), tarsus 15.2-16.1 (15.6) 

 mm. 



Resident. Common on the entire Caribbean slope and on the Pacific 

 slope eastward from Code, where I have collected it at the head of the 

 Rio Guabal. Less numerous in Darien and the drier Pacific lowlands 

 west of the Canal Zone. It occurs in foothills, up to 900 m (Ridgely, 



1976, p. 290) . It inhabits forest borders and second-growth woodland, 

 where it forages at all heights. Two males that I collected at the mouth 

 of the Rio Paya, Darien, on April 2, 1959, had the testes fully de- 

 veloped. The only other information I have on the breeding of this 

 race is Eisenmann's notation of 2 juveniles being fed on July 28, 1947, 

 on Barro Colorado Island, Canal Zone (Smiths. Misc. Coll., vol. 117, 

 no. 5, 1952, p. 49). Five collected by Strauch (Bull. Brit. Orn. Club, 



1977, p. 64) weighed from 13.1 to 14.5 g; a male he collected in January 

 was in breeding condition. 



Eisenmann reports that although often seen with wandering bands 

 of honeycreepers and tanagers, it is very frequently observed in pairs. 



On July 9, 1968, Ridgely (in litt.) found a nest in the Navy Pipeline 

 area. It was about 13 m up in a tree and contained 3 young. The nest 

 was a neat cup made of plant fibers and supported from below. Only 

 the female was seen to feed the nestlings. At Barro Colorado Island 

 young have been seen being fed in June 11, 1973, and October 8, 1972 

 (Willis and Eisenmann, Smiths. Contr. Zool. 291, 1979, p. 26) .
