Angola Lark
Amirafra angolensis
A medium-sized, stocky lark with a long heavy bill and scalloped upperparts, giving it a scaly appearance. The short rufous crest can be raised; face, eyebrow, and underparts are tawny with fine streaking on the upper breast. In flight it has white outer tail feathers. Pairs are locally common residents in montane grassland, dambos (seasonally flooded wetlands), and moist grassland. The aerial display and song are diagnostic; the male rises some 25m into the air while singing a melodious trilling song that rolls up-and-down in pitch “zi-zi-zu-zu-zu-zi-zi-zi”, before parachuting to the ground. Also calls from mounds before making a short low hop-flight with associated “prrt-prrt” sounds of mechanical wing-rattling. Also, some mimicry and loud “tew-chi-chi-tew” calls. Angola Lark is smaller and darker than Rufous-naped and larger than Flappet Lark, with a more robust bill and paler underparts.

Trocaz Pigeon
Columba trocaz
Endemic to the island of Madeira, where it is largely restricted to native laurel and tree heath forests. Body is largely gray with a purple-pink breast, and a noticeable silvery patch with black streaks on the side of the neck. The iris is yellow with a red ring around the eyes. Compare with the only other pigeon on the island, the Rock Pigeon; note differences in structure, color, and habitat preference. Song is a series of very low, groaning coos.

Swamp Francolin
Ortygornis gularis
Brown francolin with an orange throat and white-striped underparts. Shows rufous outer tail feathers and primaries in flight. Favors wet, marshy habitats such as flooded fields, wetland edges, and paddyfield plantations. Often difficult to see in tall vegetation, but emerges into the open in the early morning and late evening, usually foraging in small flocks. Gives loud gull-like “kree-ree!”, often in chorus.

Slender-billed Vulture
Gyps tenuirostris
Gaunt scavenger with long, broad squarish-tipped wings and a long hairless neck. Dark overall with pale underparts. Very similar to Indian Vulture; note darker neck without white down covering, overall darker body coloration, and less white on the bill. Lacks white rump and contrasting underwing of White-rumped Vulture. Inhabits plains, grasslands, and open forests from lowlands up into the foothills. Congregates in large flocks at carcasses, where it hisses and cackles loudly. Once common; now fairly rare.
