THE BAY-BREASTED WARBLER.
Sylvia castanea, Wils.
PLATE LXIX. Male and Female.
This species does not breed in the United States, or if it does, must
spend the summer in some of the most remote north-western districts, so
that I have not been able to discover its principal abode. It merely
passes through the better known portions of the Union, where it remains
for a very short time. There is something so very uncommon in its appearance
in different States, that I cannot refrain from briefly mentioning
it. It is sometimes found in Pennsylvania, or the State of New York, as
well as in New Jersey, as early as the beginning of April, but is only
seen there for a few days. I have shot some individuals at such times,
when I observed them employed in searching for insects and larvæ along
the fences bordering our fields. At other times I have shot them late
in June, in the State of Louisiana, when the cotton-plant was covered
with blossoms, amongst which they were busily searching for food. The
Bay-breasted Warbler, however, has so far eluded my inquiries, that I
am unable to give any further account of its habits.
