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 × .56. It is estimated that there were thirteen pairs of the birds in this colony. [Illustration 406: Hermit Warblers.

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 thick bunches of needles, so that they are very difficult to locate. They nest from March in the south to May in the northern states, laying three or four dull whitish eggs, specked or blotched with shades of brown and lilac; size .68 × .52. Data.--Worcester, Mass., May 28, 1891. Nest 30 feet up in a pine; made of pine needles and rootlets. 672. PALM WARBLER. _Dendroica palmarum palmarum._ Range.--Interior of North America, breeding about Hudson Bay and northward and wintering in the lower Mississippi Valley and the West Indies. This species is brownish yellow above and yellow on the throat and breast, the crown and streaks on the sides are chestnut. They are found during migrations on or near the ground on the edges of woods or thickets and along roadsides; have a peculiar habit of "teetering" their tail which will readily identify them. They nest on the ground in, or on the edges of swampy places, lining the hollow with grasses and rootlets. In May or June they lay three or four eggs which are creamy white, variously specked with brown and lilac; size .68 × .52. 672a. YELLOW PALM WARBLER. _Dendroica palmarum hypochrysea._ Range.--Eastern North America, breeding from Nova Scotia, northward. This is the common Yellow Redpoll Warbler of the eastern states, and is very abundant during migrations. Their habits are the same, if not identical with the interior species. Their nests are also like those of the last, placed on the ground and the eggs are indistinguishable.
