West African Crested Tern
Thalasseus albididorsalis
A large tern found strictly in coastal areas. Very pale, with a long forked tail. Shows a black cap and orange bill in breeding plumage, and a white cap, black back of the head, and yellow-orange bill when not breeding. Feeds in open ocean and saltwater bays, where it flies above the water looking for small fish. Rests on beaches, often in mixed groups with other tern species. Separated from most other terns by large size; only slightly smaller than Caspian. Separated from Caspian by the thinner orange bill (usually not deep red), shaggier crest, longer tail, and in flight the much paler wing, without a large panel of solid black. Similar to Lesser Crested Tern, but significantly larger and chunkier.

Straneck's Tyrannulet
Serpophaga griseicapilla
Small flycatcher with a gray head, an olive-brown back, a whitish throat, and a yellow belly. Note the white eyebrow and broken eye-ring. Occurs in woodland and scrub; migrates to the northeast during the austral winter. The song is a single note followed by a trill: “twie tirrrrrrrrrrrrrrrrrr.” The similar White-crested Tyrannulet has a different song and is also slightly larger, with a white crown patch that is often concealed.

Chad Firefinch
Lagonosticta umbrinodorsalis
A small brown and reddish waxbill with a blue-gray bill, a mostly gray head, and black under the tail. There are a few white spots along the shoulder. Found in dry, rocky habitat with grass and bushes. Usually in pairs or small groups. Very similar to African Firefinch, but separated by range and habitat. Also similar to Black-bellied Firefinch, but has less extensive black on the belly, and males further separated by the gray patch on the head. Calls include soft “teew” whistles, “tep” notes, and “pit-pit-pit” calls. The song is a series of identical whistled notes.

Rusty-tailed Flycatcher
Ficedula ruficauda
Medium-sized brown flycatcher with an orangish tail. Note upright posture and broad-based pale bill. Forages quietly and usually singly in the lower levels of forest edge, both through gleaning and flycatching. Breeds in open forests in hilly and montane areas at 1500-3000 meters of elevation; in the winter, favors forest edge and clearings. Song is a descending whistle followed by a brief sputter of shorter notes: “Weee-pewchewchi!”
