White-throated Robin-Chat
Dessonornis humeralis
A striking medium-sized robin-chat with a slaty gray crown and back separated from the black wings and face mask by a white bar in the shoulder and a white eyebrow, respectively. The throat and breast are white, fading into amber orange on the vent, on the rump, and in the outer tail. Pairs prefer thickets in a variety of woodland types, where they forage secretively on the ground by flicking through leaf litter. They will remain low or sit up on perches to sing their high-pitched melodious song which includes imitations of other species.

Rusty-margined Flycatcher
Myiozetetes cayanensis
One of several medium-sized, kiskadee-like flycatchers that are bright yellow below, with bold black-and-white head pattern. Rusty-margined is one of the smaller ones, with a smaller bill than Great Kiskadee. Most similar to Social and White-ringed Flycatchers; look for combination of black cheek (not gray) and especially obvious rufous in the wings. Shorter bill than White-ringed. Voice is helpful: listen for lazy-sounding, slightly burry “wheeer” call. Found in a variety of open wooded habitats such as forest edge and second growth, often around water.
Cape Gannet
Morus capensis
Gregarious, strong-flying seabird. Adults are whitish with an apricot-colored head; note also the distinctive blackish arrow-shaped tail and pointed dark wingtips and hind wing. Flocks are often seen from headlands close to the shore. Constant flapping-and-gliding flight pattern and sharp plunge-diving when foraging are unique within range. Dingy brown immatures share the overall shape and flight pattern of adults. At sea, albatrosses hardly ever flap in flight. Other gannets and boobies are mostly absent from its range. Harsh, loud rollicking “wurrah, wurrah, wurrah” given at breeding colonies and while feeding.
Striolated Manakin
Machaeropterus striolatus
Chunky little, short-tailed bird of lowland and foothill forest. Male is distinctive with bright red crown and bold white stripes on reddish belly. Female lacks red crown but shows faint streaking on sides unlike any other manakin. Inconspicuous; elaborate display dance infrequently seen. Found in the lower to middle levels of forest. Listen for its high-pitched, quiet, whistled “ch-peew” song across much of range.
