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.
American Redstart
The American Redstart is an active wood warbler weighing about 8 g with a 12.4 cm wingspan, with males showing bold black-and-orange plumage. It fans its tail and droops its wings to flush insects from foliage, a distinctive foraging behavior observed across its North American breeding range.
