DESCRIPTION. (Plate 11). Adult male and female. Winter. 

 Whole of upper-parts olive-green to olive-brown slightly more 

 yellowish-green on rump ; stripe from nostrils over and behind 

 eye yellow ; lores dusky black, feathers tipped whitish or yellowish ; 

 ear -coverts pale brown to yellowish-brown streaked pale yellow ; 

 chin, throat, and upper-breast whitish, more or less streaked 

 lemon-yellow, often with pale brownish streaks or wash on sides of 

 breast ; lower-breast and belly white with a few faint yellow 

 streaks ; flanks very pale yellowish-buff ; vent and under tail- 

 coverts pale yellow ; axillaries and under wing-coverts bright 

 lemon-yellow ; tail- and wing-feathers dark-brown, inner webs 

 fringed very narrowly dull white and outer webs more broadly 

 olive-green or olive-brown, wing-feathers with small whitish tips ; 

 wing-coverts dark brown broadly fringed and tipped olive-green 

 or olive-brown. This plumage is acquired by a complete moult 

 in July and August (sometimes beginning end June). Summer. 

 A complete moult (including wings and tail) takes place Dec. to 

 March. New plumage like winter but perhaps slightly less green 

 and more brown on upper-parts, and as summer advances abrasion 

 makes under-parts whiter and less yellow and upper-parts still 

 more brown and less green. 



Nestling. Down, greyish -white, fairly long but not plentiful ; 

 distribution, inner supra -orbital, occipital and humeral. Mouth, 

 inside orange -yellow, two faint brownish marks on tongue-spurs, 

 externally flanges lemon-yellow.
