Luapula Cisticola

Unmistakable large black swan with a red bill. When swimming this species is almost entirely black. Wings show extensive white flight feathers when flying. Juveniles are similar but dark-gray. In Australia, compare with Magpie Goose, which has white belly, and white underwing with black tips. Typically found along inland waterways, rivers, sewage ponds, and coastal lagoons and inlets. Sometimes flocks together in enormous numbers on large wetlands.

A small, active, mostly dull olive-green and gray warbler-like bird with a white eye-ring that is obvious with a good view. An uncommon resident in the forest canopy of interior Príncipe, where small groups join mixed-species flocks. A dry, reedy chittering contact call is often the first sign of their presence. Principe White-eye may join the same flocks as Principe Speirops, which is slightly larger and has a much whiter head.

A mostly green medium-sized parrot with a contrasting head, gray in females and yellow in males. Shows a blue underwing in flight. Inhabits lowland forest edge, including coconut plantations, parks, and gardens, up to at least 1750 meters of elevation. Bulkier than Cardinal, White-naped, Yellow-bibbed, and Purple-bellied Lories, with slower wingbeats, and lacks the mostly red color of those species. The similar Eclectus Parrot is larger with a bigger bill, and male is also green but has a red underwing. Singing Parrot’s voice includes a wide variety of harsh cries and a whistling bell-like song.
