The whistling warbler is a species of bird in the New World warbler family. It is monotypic within the genus Catharopeza. It has a dark back that fades into a lighter gradient going towards the chest. It also has a dark head, a dark strip on the breast, and a light orbital. Both male and female have the same plumage. It is endemic to the island of Saint Vincent in the Lesser Antilles. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest. It is threatened by habitat loss. This habitat loss is due to volcanic activity and deforestation. Whistling warblers have cup-shaped nests, and spotted eggs. Their diet primarily consists of insects.
Region
Lesser Antilles
Typical Environment
Occurs only on the island of Saint Vincent, primarily in humid forests. It uses subtropical to tropical moist lowland and montane forests, favoring dense understory and ravines. The species also occupies secondary growth and forest edges where sufficient cover remains. It is often associated with mossy, mature forest and areas recovering from disturbance, provided canopy and midstory structure persist.

The whistling warbler is the sole member of its genus, Catharopeza, and is famed for its clear, flute-like song that carries through dense forests. Both sexes look alike, with a dark, subtly graded plumage and a pale eye-ring. It is restricted to the island of Saint Vincent, where habitat loss and volcanic activity have impacted its range. Nests are neat, cup-shaped structures and the eggs are typically spotted.
Temperament
secretive and active
Flight Pattern
short rapid wingbeats
Social Behavior
Typically found singly or in territorial pairs, especially during the breeding season. Builds cup-shaped nests concealed in dense vegetation; clutches contain spotted eggs. After fledging, small family parties may persist while foraging through understory tangles.

Resident
Song Description
A series of clear, ringing whistles delivered in short phrases, often repeated and carrying far through the forest. Calls include sharp chips and thin seep notes. Males sing from shaded midstory perches, especially at dawn.
