Imitator Sparrowhawk
Tachyspiza imitator
A medium-sized black-and-white sparrowhawk with an entirely black back, chest, and hood and a white underside. Prefers dense forest interiors up to 1000 meters of elevation. Very similar to Pied Goshawk, but prefers less open habitats and has a black throat. In flight, Imitator Sparrowhawk has a thick dark rear edge to the underwing, compared to Pied Goshawk’s relatively white underwing. Imitator’s voice is relatively poorly known, but apparently vocally similar to other goshawks; a series of loud piercing whistles has been reported.

Rufous-bellied Helmetshrike
Prionops rufiventris
A boldly patterned helmetshrike of lowland forests, often seen in small vocal groups. The bill is red and the head and chin are overall silvery gray. Has a black neck band and black wings, back, and tail. The chest is white and the belly, vent, and legs are reddish. Similar to the Red-billed Helmetshrike, with which it co-occurs locally in Cameroon, but Rufous-bellied Helmetshrike can be identified by its silvery gray chin and head (including below the eye) and the more extensive reddish coloration on its belly. Calls consist of liquid whistles and repeated grating “chew-two” calls.
Curl-crested Jay
Cyanocorax cristatellus
Large jay found in savannas, semiopen areas, plantations, and occasionally gardens where it is usually encountered in small noisy groups. Note prominent black crest that curls backwards and a black throat, breast, and back. The wings and uppertail are blue while the lower half of the tail is white.
Sooty Shearwater
Ardenna grisea
Medium-sized, dark brown shearwater with silvery flashes on underwings. Narrow wings with quick, deep wingbeats. Widespread and common, especially in the Pacific; can sometimes be seen close to shore. Can be in massive flocks. Extremely similar to Short-tailed Shearwater, but Sooty is heavier and has straighter wings; also look for slightly longer bill and less rounded head. Brown plumage is reminiscent of Flesh-footed Shearwater, but Sooty is narrower-winged and has a smaller, all-dark bill.
