FAMILY PARULIDAE 



mala to central Colombia and northern Venezuela. Fairly common in 

 the Tropical and Subtropical Zones, primarily recorded from the moun- 

 tains of Chiriqui, where it has been collected as high as 2310 m (Bangs, 

 Proc. New England Zool. Club, vol. 3, 1902, p. 63), and in the Canal 

 Zone (Barro Colorado Island, Lion Hill, Juan Mina). In Bocas del 

 Toro the Golden-winged Warbler has been collected at Cocoplum 

 (Chapman, Auk, 1931, p. 121) and at Almirante (Loftin and Olson, 

 Carib. Journ. Sci., vol. 3, no. 4, 1963, pp. 194-195). On March 10, 

 1961, I took a male with no fat at Tacarcuna Village, Darien. Ridgely 

 (in lift. ) found as many as 12 above Santa Fe, Veraguas, on January 4, 

 1974. 



In Panama this species is most often noted while on migration, from 

 mid-September to early November and late March to mid-April. The 

 extreme dates are September 19 (Eisenmann, Smiths. Misc. Coll., vol. 

 117, no. 5, 1952, p. 51) and April 18 (Loftin and Olson, op. cit.). 



Buskirk et al. (Auk, 1972, p. 619), studying mixed species flocks at 

 Cerro Punta, Chiriqui, found that Golden-winged Warblers were long- 

 term followers in these flocks, although rarely were more than 1 or 2 

 individuals part of a flock. Ridgely notes that it usually occurs in 

 forest canopy or at its edge and almost always with mixed flocks. This 

 species often feeds by probing in clusters of dead leaves hanging from 

 branches. 



There seem to be no reports from the drier parts of the Pacific slope 

 lowlands from western Province of Panama, southern Code, and the 

 Azuero Peninsula, and few east of the Canal Zone. Eisenmann and 

 others have observed it occasionally on Cerro Campana and Cerro 

 Azul, and he and Morton saw 1 on Isla Coiba on October 9, 1964.
