FEMALE CfflRULEAN WARBLER. 
The female azure warbler is four and three-quarter inches 
long, and eight and a quarter in extent.^ Bill, blackish above, 
pale bluish beneath ; feet, light blue ; irides, very dark brown ; 
head and neck above, and back, rich silky green, brighter on 
the head, and passing gradually into dull bluish on the rump ; 
line from the bill over the eye, whitish, above which is the 
indication of a blue-black line widening behind ; a dusky streak 
passes through the eye ; cheeks, dusky greenish ; beneath, 
entirely whitish, strongly tinged with yellow on the chin ; sides 
of the neck, breast, flanks, and vent, streaked with dark bluish ; 
the base of the whole plumage is bluish white ; inferior tail- 
coverts, pure white ; wings and tail, very similar to those of 
the male, though much less brilliant ; smaller wing-coverts, 
bluish, tipped with green ; middling and large wing-coverts, 
blackish, widely tipped with white, constituting two very appa- 
rent bands across the wings, the white slightly tinged with 
yellowish at tip ; spurious wing, blackish ; quill-feathers, 
blackish, edged externally with green, internally and at tip 
with whitish, the three nearest the body more widely so ; the 
inferior wing-coverts, white; tail, hardly rounded, feathers, 
dusky slate, slightly tinged with bluish externally, and lined 
with pure white internally, each with a white spot towards the 
tip on the inner web. This spot is larger on the outer feathers, 
and decreases gradually until it becomes inconspicuous on the 
two middle ones. 
The description of the male need not here be repeated, 
having been already given with sufficient accuracy by Wilson, 
to whose work the reader is referred. On a comparison of the 
description and figures, he will find that the chief difference 
between the sexes consists in the female being green instead 
of blue, in her wanting the black streaks, and in being tinged 
with yellow beneath. 
We have to regret our inability to add much to Wilsoffis 
* The dimensions given by Wilson of the male must be rather below the 
standard, as they are inferior to those of the female ; whereas all the specimens 
we examined were larger, as usual.
