Resident species

Comportamiento

The call, sung repetitively during foraging, is a nasal tsee zeezeezeezeezeezee. In the rainforest they forage in the low understory, gleaning insects from the undersides of leaves and branches, often hanging upside down to do so. They are also accomplished at extracting insects from clumps of leaves and spider web at the ends of branches. They forage in small groups and will also join mixed-species feeding flocks. They nest in small grass nests shaped like balls suspended between 1–2 m above the ground. Little is known about their breeding behaviour but they are known to have clutch sizes of two eggs.
