Wallacean Whistler

Wallacean Whistler

Pachycephala arctitorquis

A thick-billed, sparrow-sized songbird. Male has a black hood, a white throat, pale gray upperparts, and a white underside. Female is rufous-brown above and whitish underneath, with dark chest streaking. Juvenile resembles a pale-billed female. Found in varied wooded habitats and forest, where pairs or single birds frequent the understory and subcanopy. Male distinguished from male Golden and Yellow-throated Whistlers by gray back and white underside. Female separated from female Golden and Yellow-throated Whistlers and from Fawn-breasted Whistler by streaked breast and strongly rufous-toned upperparts. Song is a series of strident whistles, including “choo” and “chwee” notes, sometimes in a jumbled series.

Flores Monarch

Flores Monarch

Symposiachrus sacerdotum

A small gray-and white songbird with a black mask and chin and a bright white undertail. Upperparts slate-gray and underparts clean white. Very local, restricted to the island of Flores. Found singly or in pairs in the understory of forested hills, where it often joins mixed-species flocks. Lack of peach wash on the breast separates it from Spectacled Monarch. Song is a series of repeated “weee-weee-weee-weee” notes, with a rise in pitch near the end. Also gives scratchy “churr” notes.

Morotai White-eye

Morotai White-eye

Zosterops dehaani

A tiny warbler-like songbird with a pale eye-ring, endemic to Morotai. Note black head, a broad white eye-ring, a pale forehead line, a pale patch between bill and eye, a gray back, and no yellow below. Singles, pairs, or groups inhabit forest, edge, and cultivated areas in lowlands and hills. Gives a high-pitched twittering song, characteristic of white-eyes.
