FAMILY FRINGILLIDAE

series at the Smithsonian there are 2 birds from Santa Maria, Herrera, 

 in which the black collar characteristic of intermedins appears some- 

 what narrow. There is a zone of intergradation between intermedins 

 and king ens from Code east to eastern Province of Panama. One bird 

 from Code appears fairly typical of intermedins, but 4 others have the 

 collar broken. We have no birds from the area between Code and the 

 Canal Zone. Canal Zone birds are almost all intermediate, although a 

 few specimens are all but inseparable from iungens; our only specimen 

 from Colon is in this last category. Birds from the Province of Pan- 

 ama east of the Canal Zone are more like iungens, but still intermediate. 

 Birds from Mandinga, San Bias, still show a few scattered black collar 

 feathers but are best referred to iungens. A bird from Isla Bastimen- 

 tos, Bocas del Toro, is utterly different from adjacent magnoides and 

 in lacking the collar across the breast resembles iungens, but is larger, 

 darker below, and brighter above. It probably represents an unde- 

 scribed race. The species occurs from southeastern Mexico to northern 

 Bolivia and southern Brazil. 



Figure 42. — Buff-throated Saltator, Saltador Gargantianteado, Saltator maximus. 



This saltator is rather shy, although I have found that it decoys 

 readily to whistles. It is usually found in pairs and ranges from under- 

 growth to the tops of trees. It feeds on a variety of fruits, flower corol- 

 las, and insects including wasps and ants. A female collected by Strauch 

 (Bull. Brit. Orn. Club, 1977, p. 65) weighed 46.9 g. This species has
