Medium-sized sunbird of foothill and montane forests; most often seen hanging around flowering trees and bushes, especially mistletoe. Male is blinding crimson with a white belly, a long crimson tail, and a dark moustache stripe. Male Crimson Sunbird is similar but lacks the red tail and white belly of the male Temminck’s. Female Temminck’s is very plain and difficult to distinguish from other sunbirds; watch for a distinct gray wash on the head, a white belly, and a faint russet tinge to the wings and tail. Sings a thin, soft “tsi-tsi-tsi’.
