Tufted titmouse

The generic name Baeolophus translates to "small crested" and is a compound of the Ancient Greek words : baiós meaning "small", and : lόphοs meaning "crest". The specific name bicolor means "two-colored". ==Description==

Measurements: • Length: • Weight: • Wingspan: A small bird, the tufted titmouse has a white front and gray upper body outlined with rust-colored flanks. Other characteristics include its black forehead and the tufted grey crest on its head. In juveniles, the black forehead is greatly diminished such that it may be confused with the oak titmouse, although their ranges do not overlap. Males tend to be larger than females. The song of the tufted titmouse is usually described as a whistled peter-peter-peter, although this song can vary in about 20 notable ways. ==Distribution and habitat==

The habitat of the tufted titmouse is deciduous and mixed woods, gardens, parks, and shrublands. Although it is nonmigratory and originally native to the Ohio and Mississippi River basins, factors such as bird feeders have caused it 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. ==Behavior and ecology==

The tufted titmouse gathers food from the ground and from tree branches, frequently consuming a variety of berries, nuts, seeds, small fruits, and insects and other invertebrates. Its normal pattern is to scout a feeder from cover, fly in to take a seed, then fly back to shelter to consume the morsel, though caching is also very common. The tufted titmouse can demonstrate curiosity regarding humans and sometimes perches on a window ledge and seems to be peering into the house. It may also cling to the window frames and walls of buildings seeking prey in wasp and hornet nests. The tufted titmouse is vocally active and responds to sounds of agitation in other birds. Breeding and nesting Tufted titmice nest in a hole in a tree, either a natural cavity, a human-made nest box, or sometimes an old woodpecker nest. They line the nest with soft materials, sometimes plucking hair from live mammals to use as material, a behavior known as kleptotrichy. If they find snakeskin sheddings, they may incorporate pieces into their nest. Eggs measure under long and are white or cream-colored with brownish or purplish spots. Eggs have an incubation period of 12–14 days; titmice then remain nestlings for 15–16 days. Average clutch size is five to seven eggs. Unlike many birds, the offspring of tufted titmice often stay with their parents during the winter and even after the first year of their lives. Sometimes, a bird born the year before helps its parents raise the next year's young. The tufted titmouse occasionally hybridizes with the black-crested titmouse; the hybridization range is very narrow, however, because of genetic differences. With respect to nuts and seeds, the tufted titmouse primarily prefers sunflower seeds and consumes suet and peanuts, as well. During the fall and winter, the tufted titmouse hoards food. When visiting a feeder, they take one seed per visit and store seeds within 130 feet of the feeder. ==Status==

From 1966 to 2015, the tufted titmouse population has increased by more than 1.5% per year throughout the northeastern United States. The current breeding population is estimated to be around 8 million. ==Gallery==
