About These Birds
Alder Flycatcher
The Alder Flycatcher is a small North American flycatcher weighing about 13 g with a wingspan near 14 cm. It breeds in alder thickets and wet scrub across Canada and the northern United States, identified primarily by its distinctive fee-BEE-o song rather than its plain olive-grey plumage.
Black-and-white Monjita
The Black-and-white Monjita is a vulnerable flycatcher of open grasslands, marshes, and agricultural land in southeastern South America. Males are boldly patterned in black and white and are conspicuous as they perch on fence posts and low shrubs. It is threatened by the conversion of native grasslands to crops and eucalyptus plantations.
