Habitat

Inhabits rainforest, semi-deciduous forest, gallery forest, second growth, scrub and savanna. On trinidad found in open valleys.

Reproduction

The female lays her eggs in a small cup nest made of plant fibre and placed on a horizontal tree branch. Clutch size 2 eggs incubated by female. Young fledge after about 20 days.

Feeding habits

White-chested Emeralds feed on nectar, usually taken from the flowers of large trees, but sometimes from smaller plants such as Heliconia.

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.
