Includes Chestnut-capped Warbler
- Basileuterus rufifrons
Identification
12.7 cm. Olive-green, white underparts, bright yellow chests and throats, rufous cap, white superciliary, dark eye-line fading into a rufous cheek, and a white malar marking, stout bill, round and stubby wings, and the tail is long, often raised at a high angle and flicked.
Distribution
Mexico, Central America and Colombia and Venezuela in South America. Vagrant to USA.
Taxonomy
Eight subspecies are recognized[1]:
- B. r. caudatus
- B. r. dugesi
- B. r. jouyi
- B. r. rufifrons
- B. r. salvini
- B. r. delattrii
- B. r. mesochrysus
- B. r. actuosus
The last three subspecies is sometimes considered a full species, Chestnut-capped Warbler (Basileuterus delattrii) distributed from Chiapas in Mexico to South America but excluding Yucatan, Belize and most of Guatemala; this is currently not recognized by any world wide checklists and also not by the Opus.
Habitat
Shrubby highlands near running water.
Behaviour
The diet includes insects and spiders.
The nest is dome shaped with a side entrance, made of plants and fibres, placed on the side of steep banks, rocks or logs. 3-4 eggs are laid and incubation lasts 12-14 days; it takes 9-12 days for chicks to fledge. They can have 1 or 2 broods each breeding season.
Call is a somewhat explosive 'tsup'.
