Description

The Wedge-tailed Sabrewing is a large hummingbird with a long wedge-shaped tail. Upperparts are green with blue to violet-blue crown that blends into the green nape. It has a white spot behind its eyes and a dark gray cheek. Underparts are pale gray to whitish, often slightly darker laterally. The bill is long and ranges from straight to slightly decurved, and the lower mandible is pinkish at base. The adult male is slightly larger than the female, but other than that sexes are similar. Juveniles are similar to adults but duller in coloring.

C.c. pampa are 5½ inches long. Males weigh 6½ grams and females weigh 5 grams. Its eyes are very dark brown, appearing black, and legs are dark brown.

Distribution and habitat

s. It is bold and curious, and often approaches humans. It breeds from March to July, and its nest is a well-camouflaged cup attached to a horizontal branch.

Vocalization

Calls include steady, persistent chipping and a shrill, nasal peek. The Wedge-tailed Sabrewing usually sings from dense vegetation, and its songs are complex and variable, usually including insect-like chips, squeaks, and squeals, followed by a series of excited warbled or gurgling notes. Males sing year-round, sometimes in small groups. Some tail or wing movements are associated with perched singing displays.
