The white-rimmed warbler or white-browed warbler is a species of bird in the family Parulidae. It is found in Argentina, Brazil, Paraguay, and Uruguay. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, subtropical or tropical moist shrubland, and heavily degraded former forest.
Region
Southeastern South America
Typical Environment
Occurs in the Atlantic Forest and adjacent woodlands of southern Brazil, northeastern Argentina, eastern Paraguay, and Uruguay. It favors dense understory in moist lowland and montane forests, forest edges, and second growth. The species also persists in thickets, riparian corridors, and heavily degraded former forest where cover remains. It typically keeps close to the ground or mid-story, moving through vine tangles and bamboo. Local presence is strongest where continuous understory cover is available.

Also called the white-browed warbler, it is a skulking understory bird with a bold white eyebrow and eye-ring that inspire its name. It often forages in pairs or small family groups and may join mixed-species flocks in the Atlantic Forest. Its clear, ringing song carries well through dense vegetation and helps locate this otherwise elusive bird.

Social Behavior
Usually found singly or in pairs and often maintains small territories in dense understory. Pairs remain in contact with soft calls and sometimes join mixed-species flocks moving through the mid- to lower strata. Nests are well concealed in dense cover close to the ground.

Song Description
A clear, ringing series of whistled notes delivered at a steady pace, often rising slightly in pitch. Calls include sharp chips and thin tseet notes used for contact in thick vegetation.
