YELLOWS TJMPED WABBLEB.

DENDECECA COEOIATA, 
Yellow-rumped Warbler. 
Dendrceca coronata Gray, Genera, 2cl ed., Suppl., 1842, 8. 
DESCRIPTION. 
Sp. Ch. Form, not slender. Size, moderate. Bill, shorter and more slender than in D. striata and distinctly 
notched. Feet, rather small. Wings and tail, moderate, the latter square and slightly emargiuate. Sternum, 
precisely similar in form to that of striata et pina. Tongue, rather short and fleshy, somewhat abruptly acuminate, 
slightly bifid, the end fringed with short cilia which extend a short distance along the sides. 
Color. Adult male in spring. Above, slaty blue streaked with black. Spot on top of the head, on each side 
of the body, and the rump, bright yellow. Wings, dark brown edged with slaty and whitish. Upper wing coverts, 
black, margined with slaty and tipped with white, forming two bars. Tail also brown with the six outer feathers 
spotted terminally on the inner webs with white. Beneath, including the throat, under tail coverts and under wing 
coverts, white. Sides of head, breast, and broad lines on the sides, black, with streaks of the same on the flanks; 
the black of the breast and sides is frequently mixed with white. There is a white superciliary line over the eye. 
Female, in spring, differs from the male in having less black above and below. There is a brownish cast over the 
back. There is less yellow on the sides, rump and head while the feathers of the latter are tipped with dusky. The 
ear coverts are nearly dusky and the superciliary line is not as well defined. 
The adult male, in autumn, almost exactly resembles the female in spring excepting that the patches of yellow 
are larger; there is also more of the brownish suffusion above and rather more white beneath. 
The adult female, in autumn, is much browner above than the male and has also a brownish suffusion beneath. 
The young male resembles the autumnal female. The sides of the head, yellow of the crown, and sides are 
somewhat obscured with brownish. 
The young female is so brown above as nearly to obscure the black markings of the back and the yellow of the 
crown. The black beneath is nearly obsolete and the yellow of the sides is only faintly indicated. 
The young, in the nesting plumage, have the tail and wings like the young in autumn, but the body above and 
below is streaked with black and white over which is a rufous suffusion; this is caused by every feather having a 
black centre with lighter sides. The sexes are similar. Occasionally a specimen in this stage will have a yellow 
rump; out of five which I collected on Grand Manan one is thus marked and strangely this individual proved a 
female by dissection. A nestling collected by Mr. Herrick in the above named locality has acquired the yellow rump 
through moulting before shedding any other feathers. In all stages the irides are brown; the feet and bill, black. 
OBSERVATIONS. 
Just before the moult, in autumn, the yellow patches grow much paler, in fact, become lemon-colored. I 
have taken very brightly plumaged males in spring with considerable yellow in the white of the throat, in this 
respect approaching the D. Audubonia of the West. Aside from the yellow throat, Audubonia closely resembles 
D. coronata; it has, however, less black above, morb white on the tail and wing coverts and it lacks the superciliary 
stripe of coronata, but the eyelids are white as in that species. The Yellow-rump need not be confounded w T ith any 
other species except Audubonia. Breeds from Northern New England north to the Arctic Ocean and according 
to Prof. Baird, in Jamaica. Winters in the Southern states.

DESCRIPTION OF NESTS AND EGGS. 
Nests, usually placed in evergreen trees but a short distance above the ground; composed of sticks and roots, 
lined with feathers and horse hairs. Dimensions : external diameter, '4 inches, internal, 2; external depth, 2 inches, 
internal, 1-50. 
Eggs, four in number, oval in form, white in color, generally with a ring of partly'confluent spots and blotches 
of umber, brown and lilac around the largest part of the eggs. The remaining surface is more or less dotted with 
pale brown. Dimensions from *72 x-55 to -70x-50. 
HABITS. 
The Yellow-rumped Warbler is one of the most abundant winter birds of Florida. This 
active little species frequents the hummocks of the mainland everywhere, and one can scarcely 
approach a thicket without seeing one or more of them ; but by the middle of March they
