Annobon White-eye

Found at higher elevations than other members of its genus. Shy and uncommon denizen of forest undergrowth from 1,100–2,000 m. Chunky and short-tailed, dark brown above with rich rufous neck and breast. Blue eyering. Sexes alike. Could recall an antbird, but especially note pointier bill with a thicker base. Typically found in pairs or small family groups foraging on or near the ground. More easily heard than seen: song consists of repeated phrases that can have eerie clear notes, infected whistles, or harsher phrases, but is slower and lower-pitched than the songs of other wrens in range. Usually gives the same phrase many times before switching to a new phrase.

Attractive black-and-yellow oriole. Mainly in pine-oak forest of highlands, but also in humid tropical lowlands of Yucatan Peninsula. Often in flowering trees with other species of orioles. Both sexes have a yellow head and body with a small black mask and throat patch, black wings and tail. Bill is straight and pointed. Richly whistled and slightly halting song carries well.

A distinctive swift of lowland forest that appears nearly tailless. The wings appear “pinched” at the body but are otherwise fairly straight and broad. Distinctively patterned, with a black throat, wings, and back, a white belly, a white vent, and a narrow white band on top of the rump. Vocalizations and nests are undescribed. Overall pattern is similar to Sabine’s Spinetail, but Cassin’s extremely short tail gives it a unique, forward-heavy profile.
