The female is smaller. Her plumage is soft and blended, but is not

 slight degree. The tail is graduated as in the male, but much shorter. 

 The general colour of the upper parts is dusky, with slight tints of green 

 and blue ; the head and neck dull brown, with a paler band over the eye ; 

 the lower parts light reddish- brown, the tibial feathers and lower tail-co- 

 verts dusky.

Individuals of both sexes, but especially males, differ greatly in size, 

 from the time they obtain their full plumage until they are several years 

 old, the difference sometimes amounting to several inches in the length of 

 the birds, and affording an excellent opportunity of manufacturing new 

 species.
