THE CLUCKING OR BAIKAL TEAL. 229 
O5, while im the present species at exceeds 06, The bird is 
altogether larger, having a wing of about 8°0 against about 7‘0 
in crecca. ‘Then, in this species, to judge from my specimens,* 
the lower back and rump are a grey brown, nearly uniform, 
a little darker at the shafts ; while in cvecca these parts are very 
dark brown, each feather conspicuously margined with white, 
greyish white, or buffy white. 
The wing specula are very similar, but in cvecca the tippings 
of the secondary greater coverts are broader, and are white, 
only tinged with buff posteriorly. In the present species they 
are narrower and rufous buff throughout; again, the white 
tippings of the secondaries themselves are much broader in 
this species than in crecca. 
The male assumes, after breeding, a plumage very similar 
to that of the female, from which he is only to be distinguished 
by the darker brownish red tint of the upper breast, and the 
comparatively uniform colour of the upper back, the feathers 
of which, in the female, are darker and very conspicuously 
bordered with reddish buff. 
I should add that in the female the black wing bar or specu- 
lum is often more or less shaded, especially on the later 
secondaries with a darker metallic green than in the male; but 
oe one specimen, perhaps not fully adult, there is no trace 
of this. 
_ * These are purchased and I cannot vouch for the sexing ; they might be males 
in the eclipse stage, but I think not, judging from what Schrenk and Middendorff 
say, and besides, males in this stage would hardly have been obtained in China.
