Bare-cheeked Babbler

Large, powerful falcon. Inhabits a range of expansive habitats, from grasslands and mountainsides to open woodlands. Somewhat variable, but always dark "trousers" when perched; the tail extends beyond the wingtips at rest, giving it a “short-winged” appearance. Some birds can appear pale-headed due to light-colored crowns and sparsely-marked faces. In flight, the wings are broad, with dark underwing coverts. Adults have a thin “teardrop” eyeline, whereas juveniles have a thicker one. Compare to similar Gyrfalcon and Peregrine Falcon; note “trouser” color and consistently brown upperparts. Feeds on small mammals and birds.

A recently described species from lower montane rainforest in SE Borneo. Orange chest and white belly. Male has deep blue upperparts and female gray-brown upperparts with pale eyering. Found singly or in pairs in shady undergrowth to mid-storey. Similar to Malaysian and Bornean Blue Flycatchers but usually found above the elevation of those species. Male Bornean is paler blue above and female lacks eye-ring. Malaysian lacks the extensive orange chest. Song, several descending notes followed by a single high-pitched note. Call, a single, hollow note or high-pitch double note.

Brownish sparrow with gray head and white breast with dark central spot. Very similar to Sagebrush Sparrow and once considered the same species. Bell's Sparrow is usually darker and more contrasty overall. Also note Bell's Sparrow's relatively dark and broad mustache stripe and plainer back with only indistinct, thin streaks. Found in shrubby expanses of sagebrush, primarily in California and Baja (more restricted than Sagebrush, essentially only overlapping in winter). Perches up conspicuously when singing; otherwise stays low and hidden. Frequently runs on the ground, often with tail cocked up. Song is a jumble of mechanical, musical notes, faster than Sagebrush Sparrow.
