Guayana-Strichelameisenschlüpfer Myrmotherula surinamensis

Tiny bird of riverside vine tangles and seasonally flooded forest. Distinctive male is black-and-white while female has burnt orange head and breast; both easily recognized in riverside habitat. Usually found in pairs away from mixed-species flocks. Forages actively, climbing through vines and gleaning insects from leaves. Frequently detected by contact call: a nasal doubled note. The more complex song is heard less often.
