Sichuan Treecreeper

Typically dull olive-brown mid-sized greenbul with a long bill, white throat, and reddish tail. Has a whitish eye, and usually shows pale crescents above and below the eye. Found in the thick undergrowth of forest and lush woodland at low elevations. Usually in small groups. The calls are low, gravelly “chrrr” notes, delivered in quick sequence, often by a whole group together. Somewhat similar to Gray-olive Greenbul, but larger, with a darker bill and legs. Similar to brownbuls, but separated by the pale eye and more olive-green coloration on the back.

The common oriole in the western U.S., wintering throughout Mexico. Adult males have a large white wing patch and mostly orange face with a black eyeline. Females are duller overall, mostly gray on the belly, usually with brightest orange on the face. Immature males are similar to females, but usually slightly brighter and with a black throat and eyeline. Breeds in riparian corridors and open woods; winters in any wooded habitat. Visits feeders with nectar and fruits. Females can be very difficult to distinguish from Baltimore Oriole, and hybrids do occur. Bullock's is usually brightest on the face, not the breast.

Uncommon and local, rather small hummingbird of humid forest edge, plantations, and woodlands in tropical lowlands and foothills. Perches and feeds mainly at middle to upper levels in shady understory and at edges. Note the bright red bill and greenish-gold tail (which often looks grayish). Male has violet gorget. Female has violet throat spotting, but often these areas look rather dull and grayish unless they catch the light.
