Rufous-tailed Flatbill
Ramphotrigon ruficauda
Smallish flycatcher, characteristic of forests on sandy soils and seasonally flooded forests. Heard more often than seen. Best told by bright rufous tail and flight feather edges contrasting with greenish-brown body. Singles or pairs inhabit the mid-story of tall forest and typically do not associate with other species. Sits upright and sallies to foliage for insects. In western Amazonia, told from Dusky-tailed Flatbill by clearer (less mottled) breast and extensive rufous in wings and tail. Voice is a single, lazy whistle, with characteristic strong inflection in the middle.
分类信息
The genus Ramphotrigon used to be considered to be related to Tolmomyias and Rhynchocyclus, two other genera of small tyrant flycatchers with broad bills . It is proposed that Ramphotrigon was more closely related to Myiarchus, due to shared derived features of the cranium and syrinx, and to shared similarities in nest site. Two recent phylogenetic analyses of DNA sequence data yielded somewhat incongruent information on the relationships of Ramphotrigon. Both studies confirmed, however, that Ramphotrigon is not at all closely related to Tolmomyias or Rhynchocyclus. It is found that Ramphotrigon is basal to a clade that includes Myiarchus (as well as Tyrannus and related genera),

Imperial Amazon
Amazona imperialis
A rather large, dark, and stout resident of wet upland forest. Note iridescent purple underparts, vivid green upperparts, and hefty black bill. The Red-necked Parrot, the only other native species within its range, can be readily separated from the Imperial Parrot by its largely green plumage and the red (not purple) patch on its throat. Most common call is a yelping "weep", also gives a loud, scratchy “eee-er.”
Togo Paradise-Whydah
Vidua togoensis
A nest parasite that lays its eggs in the nests of Yellow-winged Pytilias. As with other whydahs, breeding males are spectacular and bizarre, whereas non-breeding males and females are drab and inconspicuous. Breeding males are mostly black with a rufous breast, a yellow back of the neck, and a long, narrow tail. Non-breeding male and female plumages are poorly known, but show a streaky brownish back and pale underparts. Generally scarce and local in savanna and cultivated areas. Breeding male similar to other paradise-whydahs, but has a longer and narrower tail. Separation of non-breeding male and female from other paradise-whydahs is poorly understood. Not very vocal, but does mimic Yellow-winged Pytilia vocalizations, which include simple, nasal “teew” notes.
Rose-crowned Fruit-Dove
Ptilinopus regina
Tiny green and yellow dove. Yellow-orange belly and vent (note Superb Fruit-Dove has a white belly and vent). Pink forehead, gray face and neck, and often a pinkish area on upper belly. Found in rainforests, but also in coastal vine forest. This species calls frequently, and typically with a long series of gradually accelerating notes.
