Angola Swallow

Medium-sized antpitta described to science in 2020. It inhabits high elevation cloud forest along the east slope of the Andes in central Peru. Plumage is mostly chestnut brown with a pale patch on the belly. It does not show a distinct eyering or any gray in the crown, which helps to separate it from similar antpittas in the region. Voice is also very useful; songs include a single whistle repeated every four to five seconds as well as a quick, descending series. Usually stays low inside tangles where it is hard to see.

Tiny, rare hawk of mid-elevation cloud forest. Black upperparts and crown are separated by white band on back of neck, which can be indistinct and hard to see in the field. Underparts are white with broad, dark barring; also note dark comma-shaped blotch on side of neck. Immatures are tinged brown or rusty, with tan or buff neck band. Easily mistaken for Tiny Hawk, which occurs mainly at lower elevations; Semicollared has broader and more diffuse bars on underparts and more prominent neck markings. Typically stays inside forest, hunting small birds; occasionally soars.

A tiny purplish-blue bird with a chestnut cap, a soft pink belly, and a pale brow that is not always prominent, and more often grayish than white. Lacks the pale head of Crested Tit-Warbler. Breeds in high-altitude forests and scrub, but descends into foothills in the winter. Usually seen singly, in small flocks, or as a part of mixed flocks. Gives high crisp-sounding notes, usually in pairs.
