About These Birds
Sword-billed Hummingbird

Streak-throated Hermit
A small hermit hummingbird (10-11 cm) found in humid forests and forest edges of the Guiana Shield and southern Venezuela. Green plumage with streak-patterned throat and rufous underparts. Nectarivore of forest undergrowth. Often confused with Little Hermit in the field.
