no sexual dimorphism; yellow rump, vent, tail base (Panama; 2008-05-29)
|
Yellow-rumped Cacique
Cacicus cela
Native Range:
Latin America
Notes:
a yellow rump and basal half of the tail give this species its name; caciques (of which there are several species) are similar to oropendolas and likewise build hanging nests, but their nests are shorter and more oblong in comparison to an oprpendola's long conical nests; caciques are also somewhat smaller-bodied than oropendolas.
