Dormilon à nuque jaune Muscisaxicola flavinucha

Fairly large terrestrial flycatcher, breeding in the southern Andes and migrating north in winter. Favors bogs, streamsides, and other wet areas in open rocky and stony terrain, but migrants can be grounded in lowland fields. Often in same areas as other ground-tyrant species, and identified by grayish plumage tones, whitish forehead patch, and contrasting ochre nape patch (can be hard to see, depending on angle).
