164 THE COCK OF THE PLAINS. 



the disproportionately small, convex, thin -quilled 

 wing, so thin, that a vacant space half as broad as 

 a quill appears between each, the flight may he said 

 to be a sort of fluttering, more than any thing else : 

 the bird giving two or three claps of the wings in 

 quick succession, at the same time hurriedly rising 

 then shooting or floating, swinging from side to side,

 silky feathers on the neck, which on these occasions 

 stand erect. In this grotesque form he displays, in

 not unlike the sound produced by blowing into a large

 laris arundinacea, carefully constructed of dry grass 

 and slender twigs. Eggs from thirteen to seventeen,
