abdomen, had some slight red coloration at the 
base of the bill, a brownish forehead and brown 
chin, and a white spot between the eye and the 
throat (Fig. IE). These are possibly the youngest 
juveniles captured and had recently fledged. 
Juvenile males had some blue feathers on the 
neck, chest, and abdomen and, at times, had pale 
pink feathers on the collar and the tract of feathers 
that outlines the visor, which is typically dark 
gray (Fig. IB). Juvenile females differed from 
juvenile males mainly in having yellowish-green 
to green feathers on the throat, the tract of feathers 
surrounding the visor being gray or light brown, 
and in having fewer blue feathers on the abdomen 
(Fig. ID). Some juvenile males and females also 
had slight red coloration at the base of the bill 
similar to the three juveniles that were considered 
to be of indeterminate gender. 
Two juvenile males were recaptured one month 
after initial capture and still retained the typical 
juvenile plumage, although the gender of one had 
been considered indeterminate at time of first 
capture. Two males and one female that had 
gender specific juvenile plumage upon first 
capture, presented typical adult plumage upon 
recapture I month later.
