This bird resembles the last in the location of the yellow patches but has a yellow instead of a white throat, and is otherwise differently marked. They are as abundant in suitable localities as are the Myrtle Warblers in the east, nesting on the outer branches of coniferous trees at any height from the ground. The nests are made of bark strips, rootlets, plant fibre, grasses and pine needles, the three to five eggs are greenish or bluish white marked with brown and lilac; size .68 × .52. The one figured is from a beautiful set of four in Mr. C. W. Crandall's collection, and the ground color is a delicate shade of blue. Data.--Spanaway, Washington, April 23, 1902. Nest on the limb of a large fir in a clump of three in prairie country. 656a. BLACK-FRONTED WARBLER. _Dendroica auduboni nigrifrons._ Range.--Mountains of southern Arizona and Mexico. Similar to the preceding, but with the forehead and ear coverts black. Their nests and eggs are in no way different from those of Audubon's Warbler.

MAGNOLIA WARBLER. _Dendroica magnolia._ Range.--North America east of the Rockies, breeding from northern United States to Hudson Bay region and in the Alleghanies, south to Pennsylvania. Winters south of our borders. This species, which is one of the most beautiful of the Warblers, is entirely yellow below and on the rump, the breast and sides being heavily streaked with black; a large patch on the back and the ear coverts are black. They build in coniferous trees at any elevation from the ground, making their nests of rootlets and grass stems, usually lined with hair; the eggs are dull white, specked with pale reddish brown; size .65 × .48. Data.--Worcester, Mass., May 30, 1895. 4 eggs. Nest of fine rootlets and grasses about 30 feet up on the end of a limb of a pine overhanging a brook. 658. CERULEAN WARBLER. _Dendroica cærulea_. Range.--United States east of the Plains, breeding chiefly in the northern half of the Mississippi Valley, rare east of the Alleghanies and casual in New England. These beautiful Warblers are light blue gray above, streaked with black on back, white below, with a grayish blue band on breast and streaks on the sides; they have two wide white wing bars and spots on the outer tail feathers. They are found chiefly in the higher trees where they glean on the foliage; they build also usually above twenty feet from the ground in any kind of tree, placing the nests well out on the horizontal limbs, generally in a fork. The nests are made of fine strips of bark, fibres, rootlets, etc., lined with hair; the eggs are white or pale bluish white, specked with reddish brown; size .62 × .48. Data.--Fargo, Ontario, June 2, 1901. Nest in a burr oak, 18 feet from the ground on a horizontal limb.
