EASTERN ORANGE-CROWNED WARBLER
HABITS
The type race of the orange-crowned warbler makes its summer home in northwestern Canada and Alaska, from northern Manitoba to the Kowak River, migrating in the fall southeastward through the United States to its winter range in the southern Atlantic States and Gulf States, from South Carolina and Florida to Louisiana. It was discovered and named by Say (1823) early in May at Engineer Cantonment, on the Missouri River, while on its northward migration.
The main migration route is through the Mississippi Valley, northwestward in the spring and southeastward in the fall. It is very rare in spring in the northern Atlantic States, though there are a few records for even Rhode Island and Massachusetts, but there are many fall records for this region, some of them remarkably late. It seems to be rare at either season in Ohio; Milton B. Trautman (1940) gives only 10 records for Buckeye Lake, 5 in spring and 5 in fall. “Eight were noted in lowlands, within 10 feet of the ground, in dense tangles of blackberry bushes, rosebushes, or grapevines. The remaining 2, both fall birds, were in rather well-drained, brushy, and weedy fields.”
Dr. E. W. Nelson (1887) says of its status in Alaska:
Throughout the wooded region of Northern Alaska, from the British boundary line west to the shores of Bering Sea, and from the Alaskan range of mountains north within the Arctic Circle as far as the tree-limit, this species is a rather common summer resident. It is known along the shores of Bering Sea and Kotzebue Sound mainly as an autumn migrant, as it straggles to the southward at the end of the breeding season. Wherever bushes occur along the northern coast of the Territory it is found at this season, and at Saint Michaels it was a common bird each summer from the last of July up to about the middle of August, after which it became rare and soon disappeared. I have never noted it on the seacoast during the spring migration.
