Young birds in their first plumage resemble the female, 

 but males in this state may be recognized by feeling down 

 the neck in the hue of the windpipe, with the finger and 

 thumb : males having two enlargements on the tube, while 

 in females the windpipe is uniform in size throughout its 

 length. Young males may also be distinguished by a rudi- 

 mentary dark collar at the base of the neck ; they do not 

 assume the plumage by which their sex is distinguished till 

 the second year. 



The form of the trachea is shown in the vignette below.
