 female, differing only in having the wings and tail black, without 

 any green margins to the feathers and a very slight appearance of 

 blue on the lower back. A second one from the same locality is 

 rather more advanced, showing more blue on the lower back and 

 the appearance of black on the upper back, while a third one from 

 the same place has almost completely gained the adult male 

 plumage leaving only a few traces of the green female dress.
