Gray Gull

A chunky, mid-sized, remarkably drab babbler with a white throat and brownish breast. Found in the understory of rainforest at low and middle elevations, usually in small groups. Shy and skulking; rarely seen unless searched for. Very similar to Brown Illadopsis, but slightly different vocally, with higher and more inflected whistles. Also slightly paler below and more richly colored above, with a cleaner white throat. Most often detected by voice. The highly variable song consists of single-note pure whistles or short whistled phrases separated by pauses, often in a three-note ascending series; listen for a haunting clear monotone whistle. Also gives scolding calls, sometimes accompanying the whistled song.

A dull warbler restricted to southwestern Sulawesi with a pale eyebrow and central crown stripe, a largely blackish bill, dark legs, dingy olive-brown upperparts, and a pale yellow underside. Found in forests and edges in hills and mountains, often accompanying mixed-species flocks. Differs from Arctic, Japanese, and Kamchatka Leaf Warblers in darker brown coloration, dull legs, yellow underside, and lack of distinct wingbar. Song is a highly variable mix of warbles and trills.

A tiny finch of grassy areas. Key features include the brown back, red rump, orange face, and bright red bill. Found in grasslands, forest clearings, and thickets. Call include a high, thin squeaking “zwee” and a snappy ‘chi-de-chi’. Song is a sort and truncated series of whistles. Native to Africa; introduced to Japan, Spain, the Hawaiian Islands, and parts of the Caribbean.
