TETRAONID.E. 



The female is rather smaller than the male ; the band 

 before and behind the eye is less conspicuous, the light- 

 coloured edges of the scapulars and tertials are more white 

 than buff-coloured ; the chin and throat are pale buff- 

 colour ; the breast is nearly white, with much less of the 

 reddish brown colour on the upper part, the sides, or the 

 flanks. 



Very young birds, Mr. Audubon says, have the beak 

 brownish yellow ; irides light hazel ; the general colour of 

 the upper parts light yellowish brown, patched with grey ; 

 sides of the head dusky.
