of a mixed flock of small birds feeding on figs. I was interested to find 

 the throat filled with fig pulp, though the usual remains of mistletoe 

 berries were in the intestine.

This euphonia inhabits forest and second-growth woodland, where 

 it usually forages within 7 m of the ground, traveling in pairs or as part 

 of small mixed flocks. As with others of its genus, this species feeds 

 extensively on mistletoe berries. It is found primarily inside the forest, 

 coming less often to the edge, where it feeds on the fruit of Miconia 

 and other trees. Its calls include short, sharp, and nasal notes, trills, 

 and twittering chatter. A female I collected at the Candelaria Hydro- 

 graphic Station March 6, 1961, was ready to lay. Two collected by 

 Strauch (Bull. Brit. Orn. Club, 1977, p. 64) weighed 15.0 and 15.4 g. 



Two races of this species are recognized, but they are poorly marked. 

 On the basis of the U.S. National Museum series, for example, one 

 would have to consider E. a. rufivertex invalid, but some specimens in 

 other collections show the characters more clearly. The nominate race 

 occurs on the Pacific slope of Costa Rica and in extreme western Pan- 

 ama, where it is known from locations on both slopes in Chiriqui and
