Blue-tailed Emerald

A small, jewel-like hummingbird named for the brilliant blue-green iridescence of the tail feathers, male blue-tailed emeralds display glittering green plumage throughout with a contrasting deep blue-green forked tail. Found in lowland tropical forest edges, savannas, and gardens from Venezuela and Colombia east to Trinidad and south to Bolivia and Brazil. They are common in disturbed and secondary habitats, making them relatively resilient to habitat modification compared to more specialized hummingbirds.
