Dusky Broadbill
Corydon sumatranus
Strange-looking bird with predominantly dark plumage, a pale “bib,” and an enormous, deep-set pink bill. Its long body and bulky build makes it seem more like an aberrant roller than a large broadbill. Forages like a roller, frequently making forays from a perch, but much more social, often being encountered in noisy medium-sized groups. Found in forests from lowlands up into the highlands, typically in wetter areas. Gives many different calls, including an ascending series of squeaky notes, as well as mellow single notes and less pleasant-sounding croaks and rattles.
识别特征
It is mostly a charcoal gray color with a pale-yellow throat and red bill. It has a brown eye ring. There is a single white band on the wings and some white bands on the underside of the tail.

Ringed Teal
Callonetta leucophrys
Small distinctive duck. Males have a pinkish breast that is spotted in black with a rich chestnut wing and a metallic green patch on the flight feathers. Note the blue bill. Females have a striking brown-and-white face pattern, and are mostly brown above and mottled or banded brown below. In flight shows dark wings with white-and-green bands. Occurs in marshes and swamps with abundant vegetation; can be even seen perched on fences or low trees.
Great-tailed Grackle
Quiscalus mexicanus
Large, lanky blackbird with flat crown and long tail. Males have ridiculously long tails, almost as long as their body, often held in a V-shape. Males are glossy black. Females are brown with paler eyebrow and throat. Eyes yellow to white; dusky for immatures. In coastal Texas, where its range overlaps with Boat-tailed Grackle, note habitat (more generalized as opposed to strictly saltmarsh) and pale eye (not brown).
Scrub Euphonia
Euphonia affinis
Tiny finch of tropical lowlands and foothills, especially in drier areas. Occurs from eastern Mexico to Costa Rica, where it is found in open woodland, forest edge, and clearings with trees. Usually in pairs, sometimes small groups that associate readily with other euphonias, especially when feeding at mistletoe. Male has black head and throat with yellow forehead patch; female rather drab, but lacks vested appearance of female Yellow-throated Euphonia, which is slightly larger.
