Size:
These birds are 10-11 cm long and weigh 5-7 g.

Diet:
They feed mainly on the nectar of tubular flowers, namely Heliconia, Costus and Calathea, also taking some small spiders and insects.

Breeding:
Band-tailed barbthroats can breed all year round, varying among different parts of their range. The nest is a small cup made of rootlets, fungal rhizomes and fine plant materials, usually attached with spider webs to the underside of a palm frond, fern or Heliconia leave. There the female lays 2 eggs which she incubates alone for 17-18 days. Unlike most other hummingbirds, males may provide females with food during incubation. The chicks fledge about 24 days after hatching.

This species has a large breeding range and is described as uncommon. There is no available information regarding population trends.
