Bioko Batis
Batis poensis
The only batis on Bioko. Patterned like a typical batis, with a white belly and throat, black wings with a white bar, and a black face. Males have a black crown, a black back, and a black chest band, whereas females have a gray crown, a gray back, and a rusty chest band. Both sexes have limited white above the eye that can appear like a broken eyeline. Infrequently encountered but widespread from lowland forest to mid-montane forest, where it can be seen in forest and disturbed forest, including plantations. Songs include a series of high-pitched whistled notes, and a few harsh notes followed by a fast trill that descends slightly in pitch.

Van Dam's Vanga
Xenopirostris damii
Large, big-billed vanga with white underparts. Males have a black hood, and females only a black cap. Rare Madagascar endemic that is found very locally in dry deciduous forest in the north and northwest. Can be found solo or in pairs, sometimes in flocks with other vangas. Most common vocalizations are long, penetrating whistles and a short scold. Separated from Lafresnaye’s and Pollen’s Vangas by range. Separated from Madagascar Cuckooshrike by much larger bill and white rather than gray underparts.
Sulu Pygmy Woodpecker
Yungipicus ramsayi
A small woodpecker of lowland wooded areas on the Sulu Islands. Dark brown above with some white spots on the back, a white rump, throat, and underparts with faint streaking, and buffy sides of the chest. Note the alternating dark brown and white stripes on the head, with a dark forecrown. Hind crown is dark in females and bright red in males. Unmistakable. No other similarly sized woodpeckers occur in its range. Voice includes a series of rapid notes in a forceful trill.
African Crake
Crecopsis egregia
Chunky, mid-sized rail. Note the black-and-brown scalloped back, gray head and chest, barred belly, reddish bill and yellowish legs. Found in mostly seasonal wetlands, such as flooded grassland. Most often seen trailing its long legs when it flushes from grass before quickly settling back down. Two common vocalizations are a series of dry “krrr” notes and a series of deeper “du-da” notes. Similar color pattern to African Rail, but African Crake has a shorter bill and a spotted back.
