Sombre Pigeon

Brown babbler with a pale belly and reddish eyes. Bicolored crown is rusty red towards the front and black towards the back. Unscaled rufous forecrown, faintly gray-streaked breast, and slightly larger size set it apart from Scaly-crowned Babbler. Moves through the middle level of forests, often as part of a mixed flock. Favors lowland habitat on Southeast Asian mainland and middle-elevation areas on Sumatra and Borneo. Song is a series of pretty, musical whistles: “weee hoo-wee-weeee weeee.”

Extremely similar to widespread Rufous Hummingbird; identical in plumage except for males' solid green back (which can be shown by Rufous too). Breeds only along a narrow strip of coastal California and southern Oregon. On females and immature males, the only way to separate them from Rufous is by the shape of the tail feathers, which is extremely difficult to determine without good photographs.

A distinctive blue-headed sunbird that occurs in mangroves, forest edges, and gardens, almost exclusively near water. Yellow-green above and largely gray below, with a distinctive iridescent purple-blue hood that has a unique shape, covering the head, face, throat, and chest but not the back of the neck. Visually similar to other “hooded” sunbirds, most notably Green-headed Sunbird, but Reichenbach’s Sunbird always has a greenish nape, far more iridescence on the chest than the head, and a yellowish vent. Song, often given repetitively from a perch, is a mewing call followed by two hoarse whistles, “reer, tew! tew!”, while the calls are single “tiuw” notes.
