Gorgeted Wood-Quail

Rather nondescript thrush-sized brown bird with a darker face and throat. The belly is pallid and the undertail white (north part of range) or yellow (south part of range). Often in small flocks and not easily missed due to its noisy, repetitive, and powerful song. Also frequently makes harsh chattering calls. Present in many wooded habitats, absent only from dense forest or treeless desert. Often found in well-vegetated areas in dry landscapes such as gardens, orchards, and oases.

Brightly-colored warbler with a contrasting face pattern with dark cheeks and crown surrounded by bright yellow. Also shows olive back, bold white wingbars, and yellow on the breast. Intensity of color varies with age and sex; adult males are brightest, with black throat, while immatures are more washed out with a pale yellowish throat. Breeds in mature coniferous forests in northwestern North America. Winters from the Pacific coast of the U.S. to Costa Rica, with large numbers especially in the highlands of Mexico and Guatemala. Usually stays in the canopy. Sometimes gathers in large mixed flocks with other warblers and small songbirds, especially on the wintering grounds. Compare with plainer-faced Hermit Warbler, and beware that hybrids occur. Also similar to Black-throated Green Warbler, which overlaps in range most often on the wintering grounds; note Townsend’s darker cheeks and more extensive yellow on breast.

A medium-sized, bulky dark petrel with a large head and long pointed wings. It often shows a grizzled, gray scaly muzzle around the bill. It flies fast with a flexed wrist and its heavy head angled downward, giving it a characteristic appearance. It breeds on subantarctic islands between the Tristan group and western Australia, dispersing across the southern oceans between 30 and 50°S, where it is a deep ocean specialist. Several species are similar to Great-winged Petrel. Gray-faced Petrel, sometimes considered the same species, breeds off New Zealand and is almost identical except for a more extensive grizzled face patch. The smaller Kerguelen Petrel has a more contrasting silvery underwing. The gadfly petrels mostly have more pale patterning on the underwing or belly and lack the bulkiness of Great-winged Petrel.
