Introduction

Gorgeted Woodstars are most often found in the highlands where they inhabit glades and borders of humid forests, shaded plantations, and disturbed areas with trees. The smallest of the woodstars, the Gorgeted Woodstar has a white patch on the flank which can be seen during flight. Males have spectacular magenta throat patches which extend down to the lower neck and side of the chest. These woodstars often hover like a bee and get chased by large hummingbirds since they attempt to steal nectar from their floral territories. When they’re not foraging, Gorgeted Woodstars frequently perch by themselves on exposed twigs.

Field Identification

5·8–6·4 cm. Male has straight black bill; plumage generally dark metallic blue-green; gorget pinkish-purple, elongated to form auricular tufts, breast grey, white spot on flanks; tail forked, central pairs of rectrices rudimentary, outer ones elongated and reduced to shafts. Eclipse male has pale throat, cheeks black. Female bronzy green above, lower rump rufous; below cinnamon-rufous; tail rounded, cinnamon with black subterminal bar. Juvenile apparently resembles female. Male of race cleavesi differs in darker plumage, gorget less purplish, rectrices shorter and narrower.

Systematics History

Editor's Note: This article requires further editing work to merge existing content into the appropriate Subspecies sections. Please bear with us while this update takes place.

Frequently placed in genus Acestrura along with C. mulsant, C. bombus, C. astreans and C. berlepschi, but no evidence in external morphology justifies treatment in a genus separate from C. jourdanii. Thought to be closest to C. astreans. Described form Calothorax decoratus is probably a hybrid between present species and Chaetocercus mulsant. Proposed race meridae (Venezuela) invalid. Two subspecies recognized.

Subspecies


SUBSPECIES

Chaetocercus heliodor heliodor Scientific name definitions

Distribution

Andes of Venezuela (Mérida), Colombia and W Ecuador.

SUBSPECIES

Chaetocercus heliodor cleavesi Scientific name definitions

Distribution

Andes of NE Ecuador (W Sucumbíos to NW Morona-Santiago).

Distribution

Editor's Note: Additional distribution information for this taxon can be found in the 'Subspecies' article above. In the future we will develop a range-wide distribution article.

Habitat

Edges of humid forest, coffee plantations and other disturbed areas with some trees and shrubs, at 1200–3000 m; occasional visitor to sub-páramo.

Movement

Some seasonal altitudinal movements likely.

Diet and Foraging

Feeds on nectar of flowering Inga trees, coffee and other tiny flowers. Insects are caught in the air by hawking. Forages from middle strata to canopy, strategy similar to that of C. mulsant.

Sounds and Vocal Behavior

Calls while feeding and hovering include a single dry “chit”, doubled “chichit” or tripled “chichichit”. Wings make a low bee-like humming sound while hovering.

Breeding

Nests in Apr–Oct (Mérida), fledglings in Oct (Ecuador). Nest cup-shaped, built of soft downy plant material like bromeliad seeds, externally decorated with lichens, pieces of dead leaves and small twigs, glued to vertical, or saddled on horizontal branch. No further information.
Not globally threatened. CITES II. Relative abundance varies from rare to locally common. The paucity of records of this species may be in part due to its small size and inconspicuous behaviour. Range includes several national parks. In Ecuador, regularly recorded at Coca Falls and between Baeza and Tena. Report from Panama is erroneous, being based on misidentification of Calliphlox mitchellii.
