The Duida grass finch is a species of bird in the family Thraupidae.
Region
Guiana Shield tepuis
Typical Environment
This species inhabits open, windswept tepui summit grasslands interspersed with low shrubs, bromeliads, and rocky patches. It frequents edges of shrub thickets, grassy clearings, and gently sloping uplands where bunchgrasses dominate. The bird forages close to the ground and often uses low perches within sparse scrub to sing and survey. It is strongly tied to undisturbed highland grassland mosaics and is not typically found in lowland forests.
Altitude Range
1200–2400 m
Climate Zone
Highland
Ease of Keeping
Beginner friendly: 1/5
The Duida grass finch is a scarce, little-known tanager of the tepui highlands, now placed in the family Thraupidae after formerly being grouped with emberizid sparrows. It is tied to the unique summit grasslands and shrubby habitats of Cerro Duida and nearby tepuis in southern Venezuela. Its long, graduated tail and pale eyebrow help separate it from other small brown grassland birds. Because it keeps low in dense grass, it is often detected more by its thin, tinkling song than by sight.
Temperament
skulking and cautious
Flight Pattern
short rapid wingbeats, low over grass
Social Behavior
Usually seen singly, in pairs, or small family groups, keeping close to cover. Likely forms monogamous pairs during the breeding season, with nests placed low in dense grass or shrubs. Displays and song are given from low exposed perches within the grassland mosaic.
Migratory Pattern
Resident
Song Description
A thin, tinkling series of high notes and short trills, often delivered from a low shrub or grass tuft. Calls are soft chips and buzzes that can be hard to locate in windy summit habitats.
