white, covered nearly all over with reddish brown ; in some spe- 

 cimens an entire wash of this colour extends over nearly half 

 the egg, while others are blotched or freckled with it in small 

 patches over the surface generally : their medium length is 

 two inches and two lines, and breadth one inch and six lines. 



Crown of the head ferruginous brown, with a fine black 

 line down the centre of each feather ; a streak of black from 

 the base of the lower mandible down each side of the cheek ; 

 ear-coverts brown ; throat, chest, centre of the abdomen, and 

 under tail-coverts pale buff, with a fine line of brown down 

 each side of the shaft of every feather ; flanks ferruginous, each 

 feather crossed with spots of buffy white; thighs dark brown, 

 crossed like the flanks, but with redder spots ; centre of the 

 back reddish brown ; scapularies and wing-coverts brown, 

 crossed with conspicuous bars and spots of ferruginous ; tail 

 brown, crossed with ferruginous bars, and tipped with light 

 brown ; primaries blackish brown, margined on their inner 

 webs with large oval-shaped spots of buff ; bill light lead-colour, 

 passing into black at the tip ; cere and orbits pale bluish lead- 

 colour ; irides dark brown ; feet light lead-colour. 



During the first autumn the dark markings are of a much 

 deeper hue, and the lighter parts more tinged with yellow, than 

 in the adult state, when the upper surface becomes of a uni- 

 form brown, and the white of the under surface tinged with 

 yellow.
