- epik
- 56 km/h
- Risiko rendah
Cloud forest sylph with a violet tail longer than its body. Hovers at Andean blooms in Ecuador and Colombia.
- Populasi
- Not precisely quantified by number of mature individuals; species described as fairly common, with a suspected decreasing population trend (1-19% decline per decade) driven by habitat/tree-cover loss (~1.4% within mapped range)
- Habitat
- Subtropical/tropical montane cloudforest and semi-open forest-edge/shrubland habitats (forest-to-grassland transitions), at elevations of roughly 300-2,100 m, with core/optimal range around 900-2,100 m and highest densities near 1,000 m
- Fakta menarik
- Male Violet-tailed Sylphs grow dramatically elongated, iridescent violet-and-blue outer tail feathers (10-15 cm) that can be longer than the rest of the bird's body and are used in courtship display.
- Sebaran
- Pacific slope of the Western Andes of Colombia and western Ecuador; extent of occurrence ~73,000 km²; two subspecies (nominate A. c. coelestis and A. c. aethereus) occupy different portions of this Pacific-slope range
