Grallaire masquée Grallaria erythrotis

Medium-sized antpitta found in the Andes of Bolivia and far southeastern Peru near the border. Adult is grayish-brown with a rufous face and a white throat and belly. The rarely-seen juvenile is darker and heavily barred with buff. Inhabits dense understory of humid forest; usually stays on the ground when not singing, making it very hard to see. Typical song consists of three short whistles; the first note is lower in pitch than the other two.
