Bay Antpitta

Overview

The bay antpitta (Grallaria capitalis) is a species of bird in the family Grallariidae that is endemic to Peru. It is a small, plump antbird classified as Least Concern by the IUCN, with a population believed to be stable despite having a small geographic range.

Identification

• Size: 16 to 17 cm long, weighing 65 to 77 g, with very short tails.
• Plumage: Dusky brown or dark russet crown; rufous chestnut back, wings, and tail; underparts mostly rufous (darker on the breast, paler on the belly) with a whitish buff center to the belly.
• Features: Blue-gray bill and legs; dark brown iris; rufous or blackish lores; sexually monomorphic.
• Vocalisation: Song consists of a 4-note (occasionally 5-note) hollow whistle described as "HEEP hew-hew-hew"; calls are mellow, descending whistles like "heeww".

Habitat

Found on the east side of the Peruvian Andes in the Huánuco, Pasco, and Junín departments, mostly between 1,800 and 3,000 m in elevation. It inhabits the understory of humid montane forests, frequently in areas of thick regenerating vegetation such as landslide scars, secondary forest edges, and abandoned slash-and-burn fields.

Diet

The species is known to feed on insects and small snails, though detailed foraging behaviour is not well documented. It is almost entirely terrestrial, running and hopping along the ground, usually within dense vegetation.

Did you know?

As a species that thrives in regenerating habitats, the bay antpitta may actually benefit locally in the short term from human activities like low-level clearing for subsistence agriculture, although its small range makes it vulnerable to long-term habitat destruction.
