Gray-sided Thrush
Turdus feae
A dull brown thrush with a gray belly and white eyebrows. Head pattern similar to that of Eyebrowed Thrush, but Gray-sided has no orange tones anywhere on the body. Breeds in mid- to high-altitude deciduous forests; many actually move higher in the winter, into evergreen forests, unlike most other high-altitude breeders. Forages quietly on the ground, usually solitarily. Song not as rich and melodious as other thrushes; instead gives a prolonged series of distinct short phrases consisting of bouncy, “fuzzy”-sounding notes.

Cobb's Wren
Troglodytes cobbi
Endemic to the Falkland Islands, where it is found in seashore areas and offshore islets, typically in association with tussac grass. Often forages on rocky beaches, picking at food items washed up by the tide. Somewhat similar House Wren has wandered to the Falklands before, but note present species’ gray-brown head and neck, lack of a prominent eyering, and longer darker bill. Can be tame and confiding, allowing close approach. Rattling song, somewhat similar to that of House Wren, can be given from an exposed perch or deep in cover. Calls include nasal mews and harsh, dry churrs and rattles.
Crimson-collared Grosbeak
Periporphyrus celaeno
Stocky and often rather sluggish bird of tropical forest and edge in lowlands and foothills of northeast Mexico. Usually found as singles or pairs, feeding quietly at all levels in fruiting trees or bushes. Note the thick stubby bill and rather long tail. Adult male is striking: dark overall with a black hood and broad pinkish-red collar. Female is drab greenish overall with black hood similar to male. Immature is like female but with less extensive black hood.
Tsavo Sunbird
Cinnyris tsavoensis
Male is iridescent green above and dark below, with a narrow purple band across the breast. Female is nondescript, with a pale eyebrow and faint streaking across the pale underparts. Found locally in dry thorn savanna. Similar to Purple-banded Sunbird, but the male is distinguished by the lack of a maroon band across the underparts. Also very similar to Violet-breasted Sunbird, but male has a narrower purple breast band and both sexes are slightly smaller and shorter-billed. Song is a typical sunbird high-pitched jumble; also gives “chek” calls.
