Its natural habitats are subtropical or tropical dry forests and subtropical or tropical dry shrubland. It is usually seen near the ground, but sings from tall trees. It often associates in family groups or with Newtonias in mixed-species flocks.^[3] While not considered threatened, its population is inferred to be decreasing due to widespread deforestation across its range.^[2]

A 2019 phylogenetic study found the Thamnornis to be the sister species of Rand's warbler.^[4]
