It is a small songbird with a long down-curved bill and iridescent body. The black sunbird has a lifespan of approximately 3.6 years. The coloring of the birds differentiate between male and female. The male black sunbird is midnight black in color with an iridescent blue-purple stripe across the upper chest. There is a crown of lustrous green on the head, while the wings and tail are glossed blue. In many regions, the throat area is iridescent reddish-purple; however, moving northward it shifts towards a bluish sparkle (Moluccas and Kai Islands).

Crimson-backed Sunbird

Leptocoma minima

Tiny5 gForest

Crimson-backed sunbirds are tiny, even by sunbird standards, and are only 8 cm long. They have medium-length thin down-curved bills and brush-tipped tubular tongues, both adaptations for nectar feeding. The adult male is velvety red on the mantle and wing coverts and there is a broad red breast band. The crown is shiny green and there are pink-violet patches on the throat and rump. The underside from the breast below is yellowish. There is a black edge to the bib that separates the yellow of the underside.
