Tringa nebularia
Gentle-eyed large wader with a slightly upturned bill. Note overall grayish plumage with white belly and greenish legs. In flight, appears dark above with a broad white stripe up the middle of the back. Slightly larger and lankier than Common Redshank. Usually seen as singles or small groups. Listen for mellow “tewtewtew.” Feeds mainly by striding in water, picking and sweeping with its bill. Breeds across northern Europe and Asia; migrants and wintering birds in Africa, southern Asia and Australia occur in varied wetland habitats.
识别特征
Common greenshanks are brown in breeding plumage, and grey-brown in winter. When in water, they can appear very similar to marsh sandpipers but are distinguished by the shape of the lower bill which gives it an upturned appearance to the bill. They have long greenish legs and a long bill with a grey base. They show a white wedge on the back in flight. They are somewhat larger than the related common redshank. The usual call is a rapid series of three short fluty notes syllabilized as teu-teu-teu.[citation needed]<p>Like most waders, they feed on small invertebrates, but will also take small fish and amphibians.[citation needed]<p>The common greenshank is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.[citation needed] In 2024, T. nebularia was listed as Endangered under the Australian EPBC Act.

Merida Sunangel
Heliangelus spencei
Medium-sized cloud forest hummingbird found only in the Venezuelan Andes near its namesake city. Male has a glittering violet throat, green forehead, and a white neck band. Female’s throat is mottled and mostly lacks iridescence. Distinguished from Orange-throated Sunangel by throat color, white (not orange) neck band, and green belly. Formerly considered a subspecies of Amethyst-throated Sunangel.
Bioko Batis
Batis poensis
The only batis on Bioko. Patterned like a typical batis, with a white belly and throat, black wings with a white bar, and a black face. Males have a black crown, a black back, and a black chest band, whereas females have a gray crown, a gray back, and a rusty chest band. Both sexes have limited white above the eye that can appear like a broken eyeline. Infrequently encountered but widespread from lowland forest to mid-montane forest, where it can be seen in forest and disturbed forest, including plantations. Songs include a series of high-pitched whistled notes, and a few harsh notes followed by a fast trill that descends slightly in pitch.
Sooty Tern
Onychoprion fuscatus
This tropical seabird is distinctive among terns with its jet-black back, black cap, and neat white forehead. Immature birds are entirely dark blackish with white spots on wings and a white undertail. Most similar to Bridled Tern, but darker black back, dark undersides of flight feathers, and narrower white edges on tail. Sooty Tern is found in warm tropical waters worldwide. It breeds in colonies on sandy islands, but otherwise usually stays far offshore, and is rarely seen near land except when blown off course by a hurricane.
