The breeding habitat is marshes and other wet areas with dense low vegetation. The Masked Yellowthroat may also be found in other areas with dense shrub, but is less common in drier habitats.


Two white eggs with reddish-brown markings are laid in a lined cup nest low in grass or rank vegetation.

Feeding habits

The Masked Yellowthroat is usually seen in pairs, and does not associate with other species. It is often skulking, but may pop up occasionally, especially to sing. It feeds on insects, including caterpillars, which are usually captured in dense vegetation.


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.
It breeds from central Colombia, through northern Venezuela, Trinidad, the Guianas, to the regions near the Amazon River in Brazil.
