About These Birds
Belding's Yellowthroat
Belding's Yellowthroat is a vulnerable warbler endemic to a few freshwater marshes in southern Baja California, Mexico. Males have a bright yellow throat and breast, black mask, and olive-green upperparts. Its highly restricted range and dependence on marsh habitats make it susceptible to water diversion, drought, and habitat loss.
Altamira Yellowthroat
The Altamira Yellowthroat is a near-threatened warbler weighing about 11 g with a 10.8 cm wingspan, restricted to marshes and dense vegetation along the Gulf Coast of Mexico. Males display a distinctive yellow throat and mask pattern used in courtship.
