Field Identification

14–15 cm. Medium-sized to large, plump brownish flycatcher with long hook-tipped bill and short rounded wings. Adult has plain brown head with pale bufffish or tawny eyering and supraloral line, pale fulvous-brown cheeks; upperparts brown, rufous edgings on rump and tail feathers, rufous edgings on slightly darker brown flight-feathers; chin and throat white, breast brown with darker barring, flanks paler brown, rest of underparts white except buff or peachy undertail-coverts (also underwing-coverts); iris dark brown; bill blackish, mandible yellowish; legs pinkish. Sexes alike in plumage, female on average smaller than male. Juvenile is similar to adult, but has buff feather tips on upperparts (scaly appearance).

Systematics History

Until recently considered conspecific with C. brunneatus, but differs in its narrower bill (1); shorter wing/resident vs migratory status (1); buff underwing- and undertail-coverts (2); song (based on published evidence (1); more samples needed) without high-pitched introductory notes (2), whistled phrase slightly longer with more notes (2) and slightly higher pace towards the end (ns[2]) (2). Monotypic.

Subspecies

Monotypic.

Distribution

S Nicobar Is (Great and Little Nicobar).

Habitat

Forest and forest edge, both primary and secondary, and dense bushes and thickets; occasionally enters large gardens. Down to sea-level.

Movement

Resident and sedentary.

Diet and Foraging

Few data. Diet mainly insects. Usually solitary. Forages in lower canopy and bushes and lower levels of forest trees, also on ground.

Sounds and Vocal Behavior

Song a loud, rich and rapid series of descending whistles, “fee-tee, tuu-tee, fuu”, ending with low, soft “trrrr” and repeated after long pause; on Great Nicobar a wider variety of songs, most more evenly descending series of phrases ending with a few staccato notes, but can also conclude with the soft “trrr” and short whistle, or just an upslurred whistle. Calls include harsh churrs.

Breeding

No information.

Not globally threatened. Currently considered Near Threatened. Restricted-range species: confined to the Nicobar Islands EBA. Fairly common. This species has a very small global range, within which its population size (assuming that only a proportion of its range is occupied) is likely to be 2200–20,000 individuals (equating to 1450–13,300 mature individuals). The clearing and conversion of forests for plantation-planting and infrastructure development are serious threats, and these, combined with earlier habitat losses, suggest that this species is suffering a slow decline.
