Tiny, mostly warm brown hummingbird. Note distinctive curved bill; long, white central tail feathers; and dark brown throat. Found in understory of swampy forest, including second growth and abandoned plantations, primarily in coastal areas. Forages on nectar, visiting widely-spaced food sources and often seen flying between them in low, direct flight, giving a characteristic plaintive squeak. At close range, often detected by loud and erratic wing noise, like a large bee, as it weaves among understory plants. May pause briefly to investigate people. Males sing from low perches; song is a series of high, slurred notes with a distinctive pattern. Most similar to Reddish Hermit, but Little is much less rufous, lacks a black breast band, and is generally restricted to coastal swamp forests.
