Cozumel Wren

A medium-sized dark-backed albatross with pale underwings outlined by a narrow dark border and a dark notch in the armpit. The adult has a whitish head with grayish cheeks that give it a “white-capped” appearance. The gray-green bill has a yellowish tip to both mandibles. Juveniles are grayer on the head with gray bills. The species breeds on islands off Tasmania and New Zealand but disperses widely across the southern Oceans between 15 and 60°S, where it is a frequently encountered pelagic seabird. Similar albatrosses have a dark-tipped (not pale-tipped) lower half to the bill, and Salvin’s Albatross has a pale gray head and Chatham Albatross a slaty-gray head, further differentiating them from White-capped Albatross. Juveniles of these three are very difficult to separate.

Small and compact with a small bill and a shorter tail compared to larger sparrows. Males have a gray head, a vivid rusty shoulder patch, a black throat, and a yellow patch at the base of the white mustache. Females are relatively clean-looking compared to males. Song is a series of high-pitched, sharp “tzip-tzip-tzip…” notes. The flight call is higher-pitched than larger sparrows. Breeds in thick scrub and trees where it builds a large and prominent nest that has unique thermoregulating properties for hot climates. A partial and short-distance migrant; moves in tight, fast-moving flocks.

Bright yellowish white-eye with a disjunct island range; found from southwestern Borneo to southern Papua. Compare carefully with other local white-eyes. Favors open coastal forest, forest edge, scrubby areas, gardens, plantations, and towns; can be abundant on small islands. Song is a jumbled series of high-pitched notes; it is a common sound during early mornings and late evenings on islands. Calls include sharp descending cheeps and sparrow-like tweets.
