 mantle and back olive or buffish-brown, streaked black-brown ;

 fine indistinct streaks ; superciliary stripe yellowish-buff ; ear- 

 coverts buff and brown ; chin pale buff ; fairly distinct black-

 buff ; centre of lower-breast and belly white ; under tail-coverts 

 pale buff ; axillaries dusky-grey fringed very pale buff ; tail and 

 wings as in A. 'pratensis. This plumage is acquired by complete 

 moult in Aug. -Sept. Summer. — A moult takes place from Jan. 

 to March to same extent as in A. pratensis, and new plumage is 

 like winter. In worn plumage dark markings of upper- and under- 

 parts are accentuated and throat, breast, and flanks less buff.

 yellow ; externally flanges pale yellow. No spots.

 more prominently streaked on upper-parts, flanks with only a few 

 very fine dark streaks ; breast, flanks and under tail-coverts 

 washed with a warmer (not so yellowish) buff as adult. 



First winter. — Like adult. The juvenile body -feathers, lesser 

 and median wing-coverts, some inner greater coverts and imiermost 

 secondaries and occasionally central pair of tail-feathers are moulted 

 July-Sept., but not primary-coverts nor rest of greater coverts, 

 wings and tail. N.B. — Some examples retain a number of juvenile 

 feathers until they reach winter-quarters. First summer. — -Like
