Belding's yellowthroat is a New World warbler. It is a resident breeder endemic to the southern Baja California Peninsula (Mexico).
Region
Southern Baja California Peninsula
Typical Environment
This species inhabits freshwater and brackish marshes, coastal lagoons, and desert oases with dense emergent vegetation. It favors cattail (Typha) and reed (Phragmites) stands, thick sedges, and willow-lined wetlands. It also uses irrigation ditches and artificial ponds when dense cover is present. Habitat is highly patchy and restricted amid otherwise arid landscapes.

Belding's yellowthroat is a marsh-dwelling New World warbler found only in the southern Baja California Peninsula of Mexico. Males show a striking black facial mask, while females are much duller and lack the mask. The species is threatened by drainage and degradation of wetlands and freshwater oases. It is a year-round resident with strong site fidelity to dense cattail and reed beds.
Temperament
secretive and territorial
Flight Pattern
short rapid wingbeats
Social Behavior
Typically found singly or in pairs, maintaining territories within dense marsh vegetation. During breeding, pairs build a cup nest low in cattails or reeds and defend small territories. They skulk through cover and rarely venture into open areas.
Migratory Pattern
Resident
Song Description
A brisk, ringing series of repeated phrases reminiscent of 'wichity-wichity' delivered from concealed perches. Calls include sharp chips and tacks used in alarm and contact.
Plumage
Olive upperparts with bright yellow underparts; male has a bold black mask bordered by pale gray, while the female is olive-brown with a yellowish throat and no mask.
Diet
Feeds primarily on insects and other small arthropods, including beetles, caterpillars, flies, and spiders. It gleans prey from stems and leaves and occasionally sallies out to catch flying insects. Opportunistically takes small larvae and aquatic invertebrates near the water’s edge.
Preferred Environment
Forages within dense cattails, reeds, and sedges along the margins of marshes and lagoons. Often hunts low in vegetation or just above the water surface, keeping close to cover.
