Lesser Masked-Owl
Tyto sororcula
A poorly known barn-owl confined to Buru Island and the Tanimbar Islands. The pale buff face is surrounded by a conspicuous heart-shaped dark border. Underparts range from whitish on Tanimbar to buff on Buru, with scattered, well spaced dark spots and speckles. Upperparts, nape, and crown dark brownish with scattered buff markings and white spots. Thought to inhabit forests in lowlands and foothills. Readily recognized, being the only barn-owl species in range. Gives a harsh hissing call, characteristic of barn-owl family.

White-throated Screech-Owl
Megascops albogularis
Large screech-owl found in temperate forests, typically from around 2,300–3,400 m. Quite dark brown overall with small pale spots and bars covering head, back, and wings. Belly is paler tawny with dark streaks. White throat patch is usually obvious. Sexes similar. Strictly nocturnal and thus more often heard than seen; listen for a fairly short and slow series of toots that descends in pitch, often given as a duet.

Black Tinamou
Tinamus osgoodi
Large, rare tinamou found in cloud forest along the east slope of the Andes. It is uniformly sooty gray, much darker and plainer than Gray Tinamou. Rusty lower underparts are hard to see in the field. Like other forest tinamous, it is far more likely to be heard than seen. Vocalizations include a low, drawn out coo, like a dove’s but longer, and a series of low, modulated whistles.

Great Antpitta
Grallaria excelsa
Giant, upright, barred antpitta of cloud forest. Long and heavy bill, gray crown and nape, brown forehead and upperparts, and buffy throat. Underparts and cheeks ochre with strong black barring. Sexes similar. Rare and difficult to see even when singing. Mostly in darker understory in very wet cloud forest rich in palms, on the floor or at mid-levels. Song is a long, trilled “Br’ur’ur’ur’ur’ur’ur’…” ending abruptly, very similar to Undulated Antpitta but more uniform in pitch and pace. Also very similar in plumage to Undulated Antpitta, which has a smaller bill and body size, as well a blackish moustache and less contrast between forehead and crown than Great. Endemic to Venezuela with three isolated populations.
