Thick-billed Cuckoo
Pachycoccyx audeberti
Huge cuckoo that is black above and white below. Immature has white barring across its upperparts. Looks raptor-like in powerful, swooping flight. Uncommon bird of rainforest, gallery forest, and moist woodland, especially miombo. Call is a loud, repeated “wheet-it”, often given in a high display flight. Adult is separated from Great Spotted, Levaillant’s, and Pied cuckoos by its lack of a crest or white in the wing. Immature is similar to Great Spotted Cuckoo, but has black-and-white speckles on the head, and lacks a crest.
Taxonomy
In a molecular genetic study by Sorenson and Payne (2005), the thick-billed cuckoo appeared to be most closely related to the koels, consisting of the dwarf koel (Microdynamis parva) and the true koels (Eudynamys), although the evidence was not very strong and further research was required.

Range and habitat
The thick-billed cuckoo is found in humid to subhumid woodlands and gallery forests from Guinea in the northwest to Mozambique in the southeast, though it is absent from large areas of the Congo Basin. It formerly occurred in the rainforests of northeastern Madagascar, but has not been reported from that island since 1922. In its southernmost regions the thick-billed cuckoo is partially migratory, spending the southern dry season in East Africa.

Luzon Island-Thrush
Turdus thomassoni
Dark thrush of montane forests above 1000 meters, endemic to the Philippine island of Luzon. Not strikingly patterned; black with a dark brown head. Also note bright orange bill, eyering, legs, and feet. Forages at all levels of forest, picking fruit from the canopy and flipping leaves for insects on the forest floor. Song is repetitive but lovely, consisting of warbles and trills. Gives low chup notes and explosive rattling series, especially when alarmed.
Stripe-tailed Yellow-Finch
Sicalis citrina
Small yellow finch with a short bill found in savanna, grasslands, and other open habitats. Note the white patch under the tail, which can be difficult to see. Males are mostly bright yellow with an olive wash on the head and breast with an olive-brown streaky back. Females are yellowish-brown above and pale yellow below with heavy streaks. The song is a fast and nasal series: “Twee-chee-chee-chee-chee.”
Bannerman's Turaco
Tauraco bannermani
A long-tailed, bulky greenish turaco with a yellow bill, a red crest, and gray cheeks. In flight, it explodes from the canopy, showing distinctive deep red panels in the wings. Pairs or small groups bounce agilely through montane primary and secondary evergreen forest canopies. Restricted to the Bamenda highlands of Cameroon, where it is an endangered species. Presence often revealed by its song, which lasts about 5 seconds: a whooping “hooooah” followed by 7–10 harsh croaking repeated “khaaar” notes; higher-pitched than songs of most other turacos. It is the only turaco within its range with a red crest.
