FAMILY TROCHILIDAE 357 



at the head of the Rio Guabal, a female appeared feeding at flowers in 

 spite of fog and a cold wind. This has been my only personally taken 

 specimen of this race. 



In Veraguas and Code these hummingbirds appear to range at lower 

 levels than is the case farther west.

 American Museum of Natural History, collected by Arce, marked 

 Calobre without other data), chin, sides of neck, and loral area dull 

 rufous ; a wash of brown on forehead ; primaries fuscous-brown,

This is a highland species that ranges in mountain areas from Costa 

 Rica and western Panama to southeastern Colombia. Two of the three 

 geographic races currently recognized are found in Panama. At 

 present the species is little known except for the specimens that have 

 been collected.
