182 BRITISH BIRDS. (VOL. XI} 
and rump, and not all the upper tail-coverts), sometimes the central pair 
of tail-feathers, usually some innermost secondaries and coverts, some | 
median and lesser coverts, but not the rest of the wings nor of the | 
tail-feathers in the specimens examined. In some individuals some © 
winter body-feathers are retained on the upper- and under-parts. The © 
winter and summer plumages are distinct and the sexes are alike in / 
winter plumage, but in summer plumage the female has the upper-parts — 
greyer, the feathers more plentifully edged with greyish-white instead — 
of pinkish-cinnamon, the cheeks, sides of neck, chin, throat and breast © 
as in the male but usually washed paler pinkish-cinnamon (in some — 
examoles these areas are white without any pinkish-cinnamon tinge), 
new innermost secondaries and wing-coverts broadly edged and tipped 
white, pinkish-cinnamon markings in some more or less absent. 
N.B.—Four adults, all from Cozumel Island, Yucatan, all February 
specimens, had the 2nd primary in quill and were acquiring winter- 
feathers on the body, one or two worn summer-feathers still remaining 
on the back and rump. I was unable to find any spring birds — 
moulting all the tail-feathers, though Mr. F. M. Chapman, in his article — 
on the ‘“‘ Changes of Plumage in the Dunlin and Sanderling” (Bull. 
Amer. Mus. Nat. Hist., Vol. VIII., page 1), observed one specimen with 
the outer pair of tail-feathers in quill and thought it probable that all — 
the tail-feathers were moulted. 
JUVENILE.—Male and female—The upper-parts are distinct from 
the adult but the under-parts much resemble the adults in winter 
plumage. Crown, mantle, scapulars, innermost secondaries and coverts

black-brown, the feathers edged and notched creamy-yellow ; feathers 
of back, ramp and upper tail-coverts ash-brown with light buff or 
creamy-yellow tips terminating in a narrow dusky line; ear-coverts 
streaked dark sepia, feathers edged buff at sides, not white narrowly 
streaked dusky as in the adult; cheeks and sides of neck in some 
washed buff; sides of breast creamy-yellow, the feathers faintly tipped 
dusky and some with sepia marks towards the tip; (in the adult, the 
the sides of the breast are white, some of the feathers sullied with 
ash-grey and with sepia shafts); central pair of tail-feathers sepia, 
darker on inner webs and tipped creamy-yellow (not blackish-grey, 
narrowly edged white as in the adult) ; wing as in the adult but median 
coverts light sepia shading into creamy-yellow with a terminal line of 
dusky, in some with a subterminal spot or bar of dark sepia (not 
ash-grey edged white with darker shafts as in the adult) ; lesser coverts 
dark sepia, a few tipped cream instead of blackish-grey, some tipped 
white as in the adult. 
First Winter.—Male and female.—The juvenile body-feathers (not 
all the scapulars nor all the feathers of the back and rump), the tail- 
feathers, some innermost secondaries and their coverts, some median 
and lesser coverts, but not the rest of the wings, are moulted from 
September to December. After this moult the birds resemble the 
adults in winter plumage, but are distinguished by one or more worn 
spear-shaped juvenile innermost secondaries and scapulars and by the 
retained juvenile median coverts. 
N.B.—One specimen, Durban, March 29th, had the 3rd primary of 
each wing in quill and the inner remiges new, but was not moulting the 
body-feathers or tail. 
Frrest SummMerR.—Moult as in the adult and the birds are like the 
adults and only distinguished by the faint dusky terminal border when 
not too abraded, to the faded creamy edge of the innermost median __ 
coverts. .
