• Yellow-vented Eremomela Eremomela flavicrissalis

  The Yellow-vented Eremomela ranges from southern Ethiopia into parts of eastern Africa. It has gray-brown upperparts, pale gray sides to the head and whitish underparts, and searches for small insects in bushy savanna and semi-desert scrub.

• Horus Swift Apus horus

  The Horus Swift has a patchy sub-Saharan African range and catches insects in flight. Its nesting sites include eastern and southern Africa and northern Senegal.

• Nordmann's Greenshank Tringa guttifer

  A shorebird that breeds in East Asia and winters on coasts of South and Southeast Asia, Nordmann's Greenshank has a thick bill and neck and relatively short legs.

• Cryptic Honeyeater Microptilotis imitatrix

  This honeyeater occurs in the Wet Tropics of north-eastern Queensland, Australia. In a comparative study, the form called imitatrix looked darker and more olive-green than the other Graceful Honeyeater form.

• European Serin Serinus serinus

  A small finch that stays year-round in southern Europe and visits northern Europe in summer. It uses open landscapes with scattered trees.

• Fish Crow Corvus ossifragus

• Doubleday's Hummingbird Cynanthus doubledayi

  This hummingbird lives in dry forest on Mexico's Pacific coast. The study argues that plumage, voice, and range together distinguish it from the related Broad-billed Hummingbird. Their summer ranges are separate, but they may meet in winter in the Balsas Basin.

• Spice Imperial Pigeon Ducula myristicivora

  The Spice Imperial Pigeon is a large fruit-eating pigeon found on islands off western New Guinea. A black knob at the base of its bill and iridescent green wings help identify it.

• Coraya Wren Pheugopedius coraya

  This wren occurs in northern South America. It has a rufous-brown body with black-and-white markings on the head and tail, and searches for food in riverside forest undergrowth.

• Whistler's Warbler Seicercus whistleri

  This entry uses the current combination *Phylloscopus whistleri* rather than the pool's older *Seicercus whistleri*. It occurs in mountain regions around the Himalayas and forages for insects in forest understory.

• Buff-bellied Monarch Neolalage banksiana

  This monarch flycatcher is endemic to Vanuatu. Its black-and-white plumage contrasts with yellow underparts, and the 2014 survey found it in forest understory with vine tangles, often in pairs or small family groups.

• Collared Scops Owl Otus lettia

  This nocturnal owl has mottled brown plumage and ear tufts. It uses tree holes and other cavities for nesting and catches insects and small animals.

• Killdeer Charadrius vociferus

  A North American plover of open ground. It runs, pauses, and searches the ground for insects.

• Acadian Flycatcher Empidonax virescens

  Its olive back, white eye-ring, and pale wing bars are useful clues. In mature forests of the eastern United States, it darts out to catch insects.

• Yellowish Pipit Anthus chii

  The Yellowish Pipit has a large but patchy range from Panama to Argentina. It is ground-dwelling, with a streaked back and breast, and uses open, flat places. It may sing while in flight.

• Pale-throated Greenbul Atimastillas flavigula

  This long-tailed, olive-green bulbul is found in forests, dense woodland, and scrub, often in pairs or small groups. Its range extends from central into eastern Africa.

• Ross's Gull Rhodostethia rosea

  A small gull that breeds in wet Arctic tundra; breeding adults show a pale pink wash and a black collar.

• Dark-backed Weaver Ploceus bicolor

  The Dark-backed Weaver has dark brown upperparts and golden-yellow underparts. Some regional forms have grey backs. It lives in forest and closed woodland, where it searches among leaves and bark for small invertebrates.

• Yucatan Nightjar Antrostomus badius

  The Yucatan Nightjar lives in forests and at forest edges on the Yucatán Peninsula. Its camouflaged plumage helps it remain difficult to see as it hunts from perches.

• Black-crowned Waxbill Estrilda nonnula

  The Black-crowned Waxbill is mostly gray, black, and white, with a noticeable red rump. It lives in pairs or flocks in grassland and along woodland edges.

• Christmas Island Thrush Turdus erythropleurus

  Turdus erythropleurus occurs on Christmas Island. The Parks Australia account treats it as a subspecies of Turdus poliocephalus under an older classification.

• Chestnut Seedeater Sporophila cinnamomea

  This migratory bird lives in the grasslands of southern South America. Its breeding range includes Argentina, Uruguay, Paraguay, and southern Brazil; after breeding it moves north to central Brazil and other areas.

• Rough-crested Malkoha Dasylophus superciliosus

  This malkoha occurs in the Philippines. In moist lowland forest it moves through vine tangles while searching for large insects and other prey. Differences in body traits among island populations and subspecies have also been reported.
