White-eyed Gull

An odd small redstart of open dry forests. Male doesn’t look like any other redstarts; somewhat resembles magpie-robins, which do not share its range. Dark head and white wingbars are striking; slate-blue sheen on the cap is often not visible. Female has weak warm tones on the tail, unlike most other female redstarts, but her two white wingbars and white eye-ring are unique.

Visually indistinguishable from Oriental Cuckoo. Adult male is gray above with a black-and-white-barred belly and a dark gray tail; females usually look similar, but some (known as hepatic morph birds) have cinnamon-brown upperparts with black barring throughout. Intermediate in size between Common and Lesser Cuckoos; distinguished from both species by buffy (not white) under-tail feathers and from Lesser Cuckoos by yellow iris. Song is a series of five notes, with the leading note being sharper and more distinct than the four that follow; compare with Oriental Cuckoo’s series of mellow paired notes. Breeds in a wide range of different lowland and hill forests; also more open habitats outside of breeding season.

Medium-sized tern found on open ocean, beaches, and large lakes. Adults have pale gray body and black cap. Bill color differs by subspecies: most have red bill with black tip, but some Asian birds have all-black bills. First-years show dark outer primaries, dark shoulder, and black restricted to back of neck. Similar to Forster's, Arctic, and Roseate Terns. Separated from breeding Forster's Tern by entirely gray upperwings; nonbreeding Forster's shows black ear patch. Somewhat longer-billed and shorter-tailed than Arctic Tern, with paler body. Shorter-tailed and overall darker than gleaming white Roseate Tern. Often found in large flocks, especially in late summer. Gives a harsh screeching call "KEEE-yurrrr."
