Timor Leaf Warbler Phylloscopus presbytes

A small green-and-yellow warbler from Timor and Flores. Bill largely black, with a pale spot at the base of the lower part; legs dark. Olive-green above with a broad yellow eyebrow and sometimes also a faint central crown stripe. Throat white, contrasting with yellow underparts. Sometimes shows an indistinct single wingbar. Juveniles browner with no crown stripe. Found in hill and montane forest and edges in Flores, extending to lowlands and scrub on Timor. Single birds, pairs, and groups can be found in the canopy. Differs from Arctic, Japanese, and Kamchatka Leaf Warblers in dark legs, yellower underside, central crown stripe (if present), and lack of a second wing bar. Sings a short, high warble: “swit-swee-swit-swee.”
