32 BRITISH BIRDS. [voL X1. 
JUVENILE.—Much like the adult winter but the edgings’ 
of the feathers of the crown and mantle more whitish and 
less yellowish and the black streaks on the mantle rather more 
prominent. With no streaks on the upper-breast. 
First WINnTER.—The juvenile body-feathers are apparently 
moulted in autumn, but no specimen in actual moult has been 
available. First winter birds appear to be like adults. 
Grnus Hypolais. 
IcTERINE WARBLER (Hypolais icterina). 
Apurts.— Complete moult from July to September. In 
February and March another complete moult takes place, at 
all] events in some individuals, but it is possible that the wing- 
and tail-feathers are not invariably renewed at this moult. 
There is no sexual difference in the plumage. The new spring 
plumage is like that of winter but the upper-parts are more 
olive and less tinged with brownish while the under-parts 
are of a decidedly deeper yellow. 
JUVENILE.— Like the adult but the upper-parts brown with — 
only a tinge of olive; the tail- and wing-feathers and wing- 
coverts fringed with brown ; the sides of the breast and the 
flanks browner than in the adult and the rest of the under- 
parts pale vellow as the adult in winter. 
First WrinterR.—The juvenile body-feathers, lesser and 
median wing-coverts and innermost secondaries are moulted 
from August to November, but not the rest of the wings nor 
the tail. First winter birds are difficult to distinguish from 
adults but the under-parts are paler yellow and the upper- | 
parts and wing-coverts browner and less olive. 
Menopious WARBLER (H. polyglotta). 
Aputts.—Moults as in the Icterine but the autumn moult 
rather later, viz., August to October. The two species cannot 
always be distinguished by coloration even after careful — 
comparison, but usually the Melodious is browner and less — 
olive on the upper-parts and of a deeper yellow on the 
under-parts 
JUVENILE.—Very nearly resembling the juvenile Icterine 
but the upper-parts rather more buffish-brown and the 
under-parts with a tinge of cream in the yellow. 
Frrst WInTER.— The juvenile body-feathers are moulted 
in autumn but apparently not the wing-coverts. The upper- 
parts are darker brown and the under-parts more creamy- 
yellow than in first winter Icterine. 
OxtivacEous WARBLER (H. p. pallida). 
Aputts.—Complete moult from July to October. From 
January to March another complete moult takes place.
