Range
South America : West, Northwest
Habitat
Tropical to temperate zones between 1000m-2600m. Prefers savanna, cultivated areas and plantations .
Reproduction
Nest about 12 meter above ground, a small cup lined with downy plant material . Incubation 13-14 days, clutch size 2 eggs. Young fledge after about 3 weeks.
Feeding habits
Mostly nectar and small insects.
Feeds on nectar of flowers, especially red or orange tubular flowers such as bouvardia or desert honeysuckle, and will also feed on substitutes such as sugar-water mixes. Also eats many small insects and spiders.
Behavior:
Feeds by hovering and inserting its bill and long tongue in flowers to take nectar. Will also hover and perch at hummingbird feeders. Flies out from a perch to take insects in the air or from foliage, and will take small spiders (or trapped insects) from
spider webs.

Conservation
This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend is not known, but the population is not believed to be decreasing sufficiently rapidly to approach the thresholds under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
Migration
Very little data available, thought to be sedentary.
