Young Birds. According to Count Salvador]', resemble the 

 old females, but are duller in colour; the pale collar round 

 the neck is less distinct, and the grey feathers on the breast 

 have white margins. In his first breeding-dress, the young 

 male has less white on the scapulars, the white on the hinder 

 lower neck is mottled with brown, as also is the white spot at 

 the base of the bill. The latter, in the young birds, resembles 

 that of the old females, and, according to Mr. Hume, in quite 

 young birds, the iris is white or very pale yellow. 



Nestlings. Dark brown on the upper-parts, and paler brown
