( CAUTION: some birds moult all greater co-

verts); all flight feathers with only one age; the

two outermost tail feathers without white tips,

or with only a little on the outermost one; tail

feathers are juvenile and usually pointed.

zed only if retain juvenile tail feathers or grea-

ter coverts; flight feathers with only one age.

wing coverts; greater coverts with reddish ed-

ges; if moult is stopped then with two genera-

tions of flight feathers; the two outermost tail

feathers with white tips; tail feathers fresh and

rounded; in spring all wing coverts and tail

buff underparts, with yellow throat and mous-

tachial stripe; greenish head; brown bill with

pinkish tinge. Juveniles brown, with paler un-

SIMILAR SPECIES

Adult birds are unmistakable due to their head

pattern with a moustachial stripe. Juveniles

recalls to the Cirl Bunting ones, which have

greenish lesser coverts; juvenile Rock Bun-

ting have grey lesser coverts; juvenile Yellow-

hammer have chestnut rump; Corn Bunting

is bigger (16-19 mm) and without white on

outermost tail feathers.

MOULT

Complete postbreeding moult; usually finis-

hed in October; some birds stop moult to fi-

nish in wintering quarters. Partial postjuvenile

moult including body feathers and lesser and

median coverts; some birds change a variable

number of greater coverts and tertials; usually

finished late september before migration. Both

types of age have a prebreeding moult more

extense in 2nd year birds.
