Yellow-bellied Longbill

Small leaf warbler with many extremely similar relatives. Like other “Pallas’s-type” leaf warblers, has olive-yellow upperparts, pale underparts, prominent brow and crown stripes, double wingbars, and a pale rump. Unlike Ashy-throated and Buff-barred Warblers, lacks any white on outer tail edges. Pallas’s averages yellower-headed and brighter overall. Gansu and Chinese Leaf Warblers can be incredibly similar, but Lemon-rumped averages whiter-browed and yellower-bellied than the former, more contrastingly-marked on the head than the latter, and darker-billed than both. As with many other physically similar leaf warblers, best distinguished by voice and habitat. Breeds in coniferous and mixed forests at mid- to high-elevation forests, though may descend into foothills in the winter. Two song types are both highly distinctive; one is a buzzy, descending rattling trill and the other is a series of high-pitched clicking twitters. Call is a loud, strident pair of notes: “pse-tew!”

Distinctive large shorebird with a long, thin, upturned bill. Look for bold black-and-white wings and long blue-gray legs. Breeding adults have buffy-orange wash on head and neck; grayish in winter. Females have more sharply upturned bills than males. Widespread and fairly common in North America, although rare or absent from much of the eastern U.S. Usually seen in flocks, sometimes numbering into the hundreds, foraging in shallow wetlands or estuaries. Feeds by swinging its head back-and-forth through the water to catch small invertebrates.

One of the largest and rarest warblers. Breeds only in young jack pine forests in northern Michigan and Wisconsin. Winters in the Bahamas; seldom seen in migration. Blue-gray above and lemon-yellow below with broken white eye-ring, thin white wingbars, and black spotting on sides. Female slightly browner than male. Constantly pumps tail up and down. Most similar to drab female or immature Magnolia Warbler but larger with gray (not greenish) back and tail-pumping behavior. Also compare with Canada Warbler, which has bold black streaks across breast and bold yellow spectacles.
