occidentalis._

Range.--Western United States and British Columbia chiefly on the higher
ranges. Winters south to Central America.

This peculiar species has the entire head bright yellow and the throat
black; upperparts grayish, underparts white. They are found nesting in
wild rugged country, high up in pine trees, the nests being located
among bunches of needles so that they are very difficult to find. The
nests are made of rootlets, shreds of bark, pine needles, etc., lined
with fine grasses or hair. The three or four eggs are laid during June
or the latter part of May; they are white or creamy white, and sometimes
with a faint greenish tinge, specked and wreathed with brown and lilac
gray. Size .68 x .52.

670. KIRTLAND'S WARBLER. _Dendroica kirtlandi._

Range.--Eastern United States; apt to be found in any of the South
Atlantic, Middle or Central States, and in Ontario, Canada. Winters in
the Bahamas where by far the greater number of specimens have been
found.

This very rare Warbler is bluish gray above, streaked with black, and
yellow below with the throat and sides streaked. Until the summer of
1903, the locality where they bred was a mystery. The capture of a
specimen, in June, in Oscodo Co., Michigan, led to the search for the
nests by N. A. Wood, taxidermist for the Michigan Museum at Ann Arbor.
He was successful in his quest and found two nests with young and one
egg. The nest in which the egg was found contained two young birds also.
It was in a depression in the ground at the foot of a Jack pine tree and
only a few feet from a cart road. The nest was made of strips of bark
and vegetable fibres, lined with grass and pine needles. The egg is
white, sprinkled with brown in a wreath about the large end. Size .72 x
.56. It is estimated that there were thirteen pairs of the birds in this
colony.

671. PINE WARBLER. _Dendroica vigorsi._

Range.--Eastern United States, breeding from the Gulf to southern
British Provinces; winters in the Gulf States and southward.

This common eastern species is greenish above and dull yellowish below,
streaked with dusky on the sides. They are almost exclusively found in
pine woods, either light or heavy growth, where they can always be
located by their peculiar, musical lisping trill. They nest high in
these trees, placing their nests in th
