Cameroon Pigeon
Columba sjostedti
A large dark purple-gray pigeon with distinctive white spots on the breast and back, a blue-gray head, and a bright red-and-yellow bill. Often seen flying over the canopy in transit or during display flights, and sometimes perches conspicuously in the open. Found exclusively in montane forests. Vocalizations are poorly known, but appear to consist of a growl followed by multiple low coos. Overlaps locally with White-naped Pigeon, which has a white head patch and dark spots on a lighter chest, unlike the Cameroon Pigeon’s uniformly gray head and white-spotted dark body.

Scarlet-rumped Tanager
Ramphocelus passerinii
Fairly common in humid tropical lowlands. Favors evergreen forest edges, plantations, and verdant second growth, such as areas along roadsides. Forages mainly at low to middle levels often in fairly noisy small groups. Male is unmistakable if seen clearly: velvety black with a blinding scarlet rump. Female is very different: note distinctive bluish-white bill, tawny rump, and grayish head. Formerly known as Cherrie's Tanager and Passerini's Tanager.

Fork-tailed Storm-Petrel
Hydrobates furcatus
Unique among storm-petrels in having an entirely silvery-gray plumage. Aside from overall plumage color, look for contrasting dark underwings, dark mask around eye, and deeply forked tail. Breeds on offshore islands across the North Pacific, from Japan to California. Fairly common over cool water, often not far from shore. Found singly or in large flocks, often mixed with other storm-petrels.

Yellow-throated Tinkerbird
Pogoniulus subsulphureus
A small barbet that frequents forest, forest edge, and even urban areas with enough vegetation. Despite its name, the yellow throat is not often obvious; instead look for this species’ overall pale whitish underparts and black upperparts with a distinctive white moustache. Shows a small yellow rump when seen from above. Not all individuals have a yellowish throat; this is more common in the western part of the range. Similar to Red-rumped and Yellow-rumped Tinkerbirds, but note the Yellow-throated Tinkerbird’s overall bicolored appearance, its fast nasal song, and, in the west, its yellowish throat. Song is a typical fast, nasal tinkerbird song with short, rapid sets of 2-5 “po-po-po” notes given at approximately 5 notes per second, often with hesitant pauses between note sets.
