Morelet's Seedeater
Sporophila morelleti
Fairly common little bird of grassland and weedy areas in the tropical lowlands and foothills. Occurs from Texas to Panama. Often in flocks, mixing readily with other “weed-eating” small birds. Plumage is very variable, but all birds have a stubby dark bill with a curved culmen. Usually shows two whitish wingbars. Breeding plumage males with a black cap and bold white collar are usually outnumbered by female-plumaged birds, which are plain brownish, sometimes showing buffy wingbars.
分类信息
This species was formerly considered conspecific with the cinnamon-rumped seedeater (Sporophila torqueola), with the combined species known as white-collared seedeater. However, with the discovery that cinnamon-rumped and Morelet's are deeply divergent from one another genetically, don't intergrade, and aren't even each other's closest relatives within the genus, they are now treated as separate species.

分布与栖息地
It ranges from a small area along the Rio Grande near San Ignacio, Texas in the United States south through eastern Mexico and Central America to Panama. It mainly inhabits tropical and subtropical grasslands, savannas, and shrublands but can also be found in pastures, arable land, and heavily degraded former forests.

Belcher's Gull
Larus belcheri
Rather large, dark-backed gull along the Humboldt Current coast. Fairly common to locally common, favoring fishing harbors, beaches, and river mouths; ranges over inshore coastal waters and not found inland. All ages have a broad, clean-cut black tail band and a red-and-black bill tip. Breeding adult has clean white head and lacks the white spots in wingtip seen on the larger and bulkier Kelp Gull. Immature and nonbreeding plumages have a distinctive dark hood and yellowish legs.

Black-tailed Whistler
Pachycephala melanura
Chunky, rounded songbird with heavy thick bill. Found across a wide range of habitats across its range: largely mangroves in Australia, but also inhabits freshwater swamps in New Guinea and forests and forest edge on smaller islands. Male has an olive-yellow back, black head, white chin, bright yellow underparts, and thick yellow hindcollar. Female plain gray above, paler gray below, with yellow undertail and in some subspecies a yellow belly. Overlaps very marginally with the very similar Golden Whistler in eastern Queensland, but note mangrove habitat as well as slightly longer bill and darker uppertail; also note significant yellow on underparts in female and different song. Vocalizations include variations on whistled songs, sometimes with a whip-like ending.

Choco Brushfinch
Atlapetes crassus
This chunky bird is dingy yellow below and dark brownish above with a tawny crown. Sexes similar. Could be confused with Yellow-breasted Brushfinch, which is found at higher elevations and has a brighter rufous crown. Pairs or small groups are found foraging in the lower levels of montane forest, edges and tangles, often clambering around a couple meters from the ground. Found from around 600–2,500 m.
