746a. CAPE VERDIN. _Auriparus flaviceps lamprocephalus._ Range.--Lower California. This new sub-species is said to have shorter wings and tail, and also to be brighter yellow on the head. Its habits and eggs will not differ from those of the common Verdin or Yellow-headed Bush-Tit. WARBLERS, KINGLETS and GNATCATCHERS. Family SYLVIIDÆ 747. KENNICOTT'S WILLOW WARBLER. _Acanthopneuste borealis._ Range.--Asia, casually found in Alaska. This species breeds in the extreme northern parts of Asia, and I believe its eggs have never been found on this continent. They build their nests of moss and grasses, on the ground in open woods, concealing them under tufts of grass or tussocks of earth. The three to five eggs are white, spotted with pale reddish brown. Size .70 × .50. 748. GOLDEN-CROWNED KINGLET. _Regulus satrapa satrapa._ Range.--North America, breeding from northern United States northward, and south in the Rockies to Mexico, and in the Alleghanies to the Carolinas; winters throughout the United States. This rugged little fellow appears to be perfectly content in our northern states even during the most severe winters and leaves us early in the spring for his breeding grounds farther north. They are usually found in company with Chickadees and, like them, may be seen hanging to twigs in all sorts of positions as they search for their meagre fare. Their nests are large, round structures of green moss, bark strips and fine rootlets, very thickly lined with soft feathers; these are placed in forks or partially suspended among the branches of spruce trees, usually high above the ground. During June they lay from five to ten eggs of a dull whitish or grayish color, spotted heavily with pale brown and lilac. Size .55 × .42.

WESTERN GOLDEN-CROWNED KINGLET. _Regulas satrapa olivaceus._ Range.--Pacific coast from southern California to Alaska. This variety is said to be brighter colored than the last; its habits and eggs are the same in all particulars. 749. RUBY-CROWNED KINGLET. _Regulus calendula calendula._ Range.--North America, breeding from the northern border of the United States northward, and farther south in mountain ranges; winters in southern United States. This little bird is of the size of the Golden-crowned Kinglet (4.25 inches long) and has a partially concealed patch of red on the crown, not bordered by black and yellow as is the last species. Their nests are similar in construction to those of the last species and are situated in coniferous trees at any altitude from the ground. Their four to nine eggs are creamy white, finely specked with reddish brown. Size .56 × .44. [Illustration 442: Golden-crowned Kinglets.] [Illustration: White.] [Illustration: C. A. Smith.
