Reichenbach's Sunbird Anabathmis reichenbachii

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.
