Taxonomy:
Order Apodiformes
Family Trochilidae

Range:
This species is found along the Andes mountain range, in Ecuador and southern Colombia.

Size:
These birds are 11,5-13 cm long and weigh 7,5-8 g.

Habitat:
The Ecuadorian hillstar is found in high-altitude grasslands and pastures, and sometimes also in humid rocky slopes, on volcanic mountains up to the snowline. They occur at altitudes of 3.500-5.200 m.

Diet:
They feed on the nectar of various flowers, particularly the orange flowers of the Chuquiragua scrub, but also take several insects and spiders.

Breeding:
Ecuadorian hillstars can breed all year round, with a peak in October-February. The nest is a small cup made of moss, roots, dry grass, feathers, rabbit fur and vegetable down, typically placed in a cave, gully or crevice in a steep ravine, often below an overhang. The nest may also be suspended from small ferns or built in trees such as Polypelis, up to 6 m above the ground. The female lays 2 white eggs, which she incubates alone for 14-19 days. The chicks are fed by both parents and fledge 3-4 weeks after hatching.

Conservation:
IUCN status - LC (Least Concern)
This species has a restricted breeding range and is described as common and patchily distributed. The population is suspected to be stable in the absence of evidence for any declines or substantial threats.

Oriental magpie-larks breed in February-August. The nest is a loose cup made with grass and dried leaves, twigs, moss and roots. The nest is lined with plant fibres or grass and placed in a hole in tree, in a wall, in a building, a ledge under a roof, or sometimes also in thick scrubs, in forks of branches in a small tree, even in an old tin can. The female lays 3-5 pale greenish-blue eggs with reddish spots, which are incubated by both parents for 12 to 13 days. The is no information regarding the fledging period, but the chicks are raised by both parents and remain in the parental territory until the next breeding season.

Conservation:
