The riverbank warbler, sometimes known as the Neotropical river warbler or just river warbler, is a species of bird in the family Parulidae.
Region
Amazon Basin and Andean foothills
Typical Environment
Occurs widely in northern and western South America, including parts of Venezuela, Colombia, Ecuador, Peru, Bolivia, the Guianas, and northern Brazil. It favors forested river margins, shaded creeks, and flooded varzea and igapó edges. Most often found along clear or tannin-stained streams with dense understory cover, root mats, and overhanging banks. It uses both primary and secondary forest as long as riparian vegetation is intact. Local presence can be patchy, tracking suitable streamside habitat.
Altitude Range
0–1700 m
Climate Zone
Tropical
Ease of Keeping
Beginner friendly: 1/5
A shy, streamside warbler of the Neotropics, it forages along shaded creeks and riverbanks, often among tangled roots and overhanging vegetation. It frequently flicks its tail while moving mouse-like along the water’s edge. The species is sensitive to riparian habitat degradation but persists where forested stream corridors remain. Its thin, insect-like song can be easily overlooked beneath the sound of running water.
Temperament
secretive and skulking
Flight Pattern
short rapid wingbeats, low over water or along banks
Social Behavior
Usually solitary or in pairs, especially during the breeding season. Nests are placed low near water, often in banks, among roots, or concealed in dense vegetation. Territorial along suitable stretches of stream, with pairs maintaining linear riparian territories.
Migratory Pattern
Resident
Song Description
A thin, high, insect-like series of trills and chips, often delivered from low cover near the water. Calls are sharp ticks and seep notes that can be masked by stream noise.
