INSECTIVOROUS BIRDS. 
YELLOW WREN, or WILLOW WREN. 
(Sylvia Trochilus , Lath. ii. p. 512. Temminck, i. p. 224. (Ed. 2.) 
Yellow Titmouse, Catesby, i. p. 63.) 
Sp. Charact. — Pale olive ; above the eye a line of dull yellow ; be- 
low yellowish, fading to white on the belly ; wings and tail grey- 
ish-brown, edged with olive ; the tail emarginate, exceeding the 
length of the wings 12 lines ; 2d primary the length of the 6th. 
This hardy species, more rare in America, inhabits 
also every part of Europe from Italy to Sweden. From 
the United States, at the approach of winter, it migrates 
to Jamaica, and other islands of the West Indies. In 
the month of October they visit this vicinity on their way 
to the South, and keep busily but silently foraging among 
the low bushes of the gardens. They feed upon flies, 
gnats, caterpillars, and various larvae. They frequent the 
tops of trees, more particularly willows and alders, from 
whence they often rise singing. The notes, though rath- 
er low, are soft, and sweetly varied, and in Europe, 
where they breed, continue to the month of October. It 
makes its nest in holes, at the roots of trees, among moss 
and leaves, or in dry banks, and arches it over like that 
of the European Wren ; it is made chiefly of moss, lined 
with wool and hair. The eggs are 5 to 7, of a reddish 
white, with large purplish-red spots, rather numerous at 
the great end. According to Catesby they breed in 
North Carolina. 
Length about 5 inches. Iris hazel. Legs yellowish-brown. In 
th e female the lower parts are of a paler and less pure yellow.

with a triangular spot of yellowish- white ; 2 or 3 lateral tail-feath-
