Habitat

Habitat preference is the canopy and sub canopy of (the lower edge) subtropical or tropical moist montanes.

Reproduction

No data available.

Feeding habits

The bird is an active insectivore (insects and spiders) foliage-gleaner, hopping quickly about in the leaves and slender twigs at the tips of branches from 10 meters up to the canopy. Often the bird gives nervous double wing-flicks between foraging maneuvers. Almost always accompanying mixed-species flocks .

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.

Migration

Sedentary throughout range.
