Taczanowski's Ground-Tyrant

A rather small, neat swallow with a distinctive burnt-orange skullcap extending onto the cheeks like a helmet, a rufous rump, and boldly streaked underparts. It is mostly resident in equatorial Africa, and a wet season breeding visitor to the northwest and southeast parts of its range. Pairs and small groups forage over grassland, woodland, and cultivation, generally at lower elevations than Greater Striped Swallow. The flight is fairly strong, much like that of a Barn Swallow. The larger Greater Striped Swallow is similar to Lesser Striped Swallow but with fewer and finer streaks, especially on the throat and ears, giving it a more open-faced appearance.

The largest nuthatch in the world, about the size of a bulbul. Coloration similar to many other nuthatches: gray above and white below, with a thick black line through the eye. Picky in its habitat preferences and as a result generally uncommon or absent through much of its range; requires extensive stands of mature tall pines in foothills and montane regions. Can be quite loud, giving a hoarse chatter reminiscent of a corvid; also gives a clipped fluty whistle.

A medium-sized prion. The dark “M” across the back is found in all the prion species, but is noticeably less pronounced on the Slender-billed Prion. Slender-billed Prion has a very pale face, prominent white eyebrow, and very narrow black tip to the upper tail. As suggested by its name, the Slender-billed Prion has the thinnest and least robust bill of the prion species. Breeds on islands in the southern Indian Ocean, the Falklands, and around subantarctic South America while ranging throughout southern oceans during the nonbreeding season. Very difficult to distinguish from other prion species at sea, but distinguishable with careful observation of all described features.
