you. x1] MOULTS OF BRITISH PASSERES. 39 
S. uw. undata labelled February and one of S. wu. toni labelled 
March were moulting in the body-plumage, so further material 
may reveal a spring moult. The female is like the male 
but has a browner (less slate) crown and the rest of the upper- 
parts are of a slightly paler brown than in the male. The 
under-parts are considerably paler and more brown and 
less pink than in the male. The tail and wings are browner 
and less blackish. Abrasion makes the male in summer 
greyer on the crown, while the white tips and edgings of 
the feathers of the under-parts gradually wear off, making 
the pink more uniform and richer. 
JUVENILE.—Somewhat like the adult female but the 
upper-parts darker—more dark earth-brown to dark sooty- 
brown ; under-parts brownish-buff without any tinge of pink. 
First WiIntTER.—The juvenile body-feathers, wing-coverts 
and innermost secondaries are moulted from August to 
November but not the primary-coverts, tail-feathers nor 
the rest of the wing-feathers. First winter birds are like 
the adults, but in the male the tail-feathers are rather browner 
and have brown instead of slate-grey edgings. 
GENnus Agrobates. 
Rurous WARBLER (Agrobates g. galactotes). 
Aputtis.—Complete moult in autumn beginning sometimes 
in July. Nomoultinspring. There is no sexual nor seasonal 
difference in the plumage. 
JUVENILE.—Like the adults but the upper-parts rather 
paler and more sandy and less chestnut; the feathers of 
the throat, breast and sides with dark sandy tips giving a 
slightly-speckled appearance; tail-feathers with less black 
than in adults and usually with none at all on the outer-webs. 
First WInTER.—The juvenile body-feathers, apparently 
the wing-coverts and two or three innermost secondaries, 
are moulted from June to October, but not the rest of the 
wing-feathers nor the primary-coverts. The tail appears 
to moult also asin all the winter and summer birds examined, 
the tail-feathers had well marked black subterminal bands, 
but no examples actually moulting the tail have been available. 
Genus Turdus. 
Dr. C. B. Ticrnurst has already fully described in this 
magazine (Vol. III., pp. 243-250, 321-326) the plumages 
and moults of the British Thrushes, with the exception of 
White’s Thrush and the Dusky Thrush, so that it will be 
necessary only to give here details of these two species and 
a summary of the genus. 
_ The adults of all the British species of T'urdus have a 
‘complete moult from July to October. There is no
