Measurements:<p>These small birds have a white front and grey upper body outlined with rust colored flanks. Other characteristics include their black foreheads and the tufted grey crest on their heads. In juveniles, the black forehead is greatly diminished such that they may be confused with the oak titmouse (although their ranges do not overlap). Males tend to be larger than females.<p>The song of the tufted titmouse is usually described as a whistled peter-peter-peter, although this song can vary in approximately 20 notable ways.

分布与栖息地
Its habitat is deciduous and mixed woods as well as gardens, parks, and shrublands. Although the tufted titmouse is non-migratory and originally native to the Ohio and Mississippi River basins, factors such as bird feeders have caused these birds to occupy a larger territory across the United States and stretching into Ontario and Quebec in Canada. During the second half of the 20th century and into the 21st century, the species' range has been expanding northwards.

Forest Thrush
Turdus lherminieri
An uncommon robin-shaped inhabitant of moist forests where it is usually found feeding on insects and fruits. Its rich gray-brown upperparts and head, combined with bold scaly underparts make it unmistakable within its range. The call is a loud smack. Sings a variety of whistles and other sounds, often uttered in distinct phrases usually from a concealed mid-level perch.
Fulvous Wren
Cinnycerthia fulva
Reddish-brown wren with a faint pale eyebrow found in the understory of humid montane forest. Larger and longer-tailed than the tiny Mountain Wren, which also has a bolder eyebrow. Replaced at the northern end of its range by the very similar Peruvian Wren. Forages singly or in pairs low in bushes and near the ground. Listen for its loud song, a flowing series of whistles and trills.
Caspian Gull
Larus cachinnans
Difficult to separate from Yellow-legged Gulls and Herring Gulls without a careful appraisal of plumage characters. Candidate birds may draw attention by slender-billed, long-legged, and slim appearance. Flattened crown, rather small dark eyes, and usually unstreaked head are also useful characters. Wingtip (primary) feathers in adults have long tongues of white that penetrate into the black tips. Juveniles have prominent pale underwings. Breeds and winters predominantly on inland water bodies with some movement toward coasts in winter.
