Habitat

This species is found in the upper levels of forests, secondary growth and the edges of mangrove swamps.

Reproduction

The bottle nest is made of plant fibre and suspended from a branch, usually near a wasp nest, which presumably provides some protection from predators. The typical clutch is two or three creamy white eggs, which are marked with violet, mostly at the larger end. Incubation by the female is 17 days to hatching.

Feeding habits

Yellow-breasted Flycatcher are inconspicuous birds, tending to keep to high perches from which they sally forth to catch insects.

Conservation

This species has an extremely 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 appears to be stable, and hence the species does not approach the thresholds for Vulnerable 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.
Yellow-breasted Flycatcher status Least Concern

Migration

Sedentary throughout range.
