upon the throat and forepart of the neck lengthways 

 on each side. The feathers composing this part, as in 

 the greater number of other species, present the scaly 

 form, and to the touch feel soft like velvet. The 

 upper parts of the neck, back, rump, and lesser wing- 

 coverts, are bright golden green ; the forepart of the 

 throat, and lower parts, are greenish, mingled with 

 gray, becoming whitish as they approach the tail. 



The young birds have the upper parts of a duller 

 tinge, beneath gray, and the scaly patch is much less 

 brilliant, and loses the scaly texture of the feathers.
