Zebra Waxbill

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!”

Adult males are almost entirely orange with bright white chest and some green on the back (can be solid green like Allen's Hummingbird). Throat is iridescent, and depending on the light, can look anywhere from red to orange to yellow to lime green. On females and immatures, look for orange on sides and tail to separate from Anna's and Black-chinned. Found in a variety of wooded habitats; more common in migration in suburbs, meadows, and other brushier areas. Feeds on nectar and tiny insects.

A crow-like bird with a long, narrow tail. Flashy black-and-white pattern distinctive within range. An endangered species, this is a rare but conspicuous bird of juniper forest and riverine scrub between 2200–3000m in the Asir massif of southwestern Saudia Arabia, where it typically moves in pairs and small family groups. Very vocal, often giving loud querulous grating “kuaynk-kuaynk” calls and high-pitched woodpecker-like “keenk” notes. Does not overlap in range with Eurasian Magpie, but Asir has less white in the plumage, a larger bill, and a shorter tail.
