Blue-and-white Swallow

Beautiful grayish-white pigeon with black wing- and tail-tips. Rare, little-known, and extremely localized; now found only on islands off western Sumatra (though may occasionally wander onto the main island), where it forages in lowland and hill forest. Vocalizations poorly understood and seldom heard; documented giving deep, sonorous, rising coos.

Very large for a hummingbird; size alone separates from many other species. Males and females similar: gray below, dusky-greenish back, brown rump, and large dark tail with prominent white corners. Also note white eyebrow and short white mustache stripe. Male has bright blue throat patch, difficult to see unless the light hits it just right. Uncommon in canyons and mountains with mixed pine-oak forests, primarily in Mexico but barely extending into the U.S. Very similar to Amethyst-throated Mountain-gem, especially if you can’t see the throat color. Blue-throated is slightly larger and paler overall with larger white (not gray) tips on the tail feathers; females are plainer, lacking the buffy tones of Amethyst-throated. Also compare with Rivoli’s Hummingbird, especially females; Blue-throated is shorter-billed and plainer (less speckled) on the underparts.

Distinctive crow with an ashy gray body and contrasting black head, wings, and tail. Essentially unmistakable unless seen in poor light or at a distance. Birds average paler in eastern parts of range, with “Mesopotamian Crow” of Iraq and southwestern Iran being almost black-and-white. Found in varied open and semiopen habitats from towns and farmland to open woodland and moorland. Found in pairs or small groups, not usually in large flocks except at roosts. Hybridizes with Carrion Crow where the two overlap. Gives typical crow caws, often indistinguishable from those of Carrion Crow.
