Tufted titmouse

  (Redirected from Tufted Titmouse)

The tufted titmouse (Baeolophus bicolor) is a small songbird from North America, a species in the tit and chickadee family (Paridae). The black-crested titmouse, found from central and southern Texas southward,[2] was included as a subspecies, but now is considered a separate species, (Baeolophus atricristatus).[3]

These small birds are approximately six inches in length, with 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.[4]

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.[5]

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 Ohio and Mississippi, factors such as bird feeders have caused these birds to occupy a larger amount of territory across the United States and stretching into Ontario, Canada.[4][6] From 1966 - 2015 the tufted titmouse population has increased by more than 1.5% per year throughout the northeastern U.S., Michigan, and Wisconsin.[7]

The tufted titmouse gathers food from the ground and from tree branches. It eats berries, nuts, insects, small fruit, snails, and seeds. Caterpillars constitute a major part of its diet during the summer. Titmice will stash food for later use.[8] The titmouse can demonstrate curiosity regarding humans, and sometimes will perch on a window ledge and seem to be peering into the house. It may cling to the windows and walls of buildings seeking prey in wasp and hornet nests.[citation needed] It is a regular visitor around bird feeders.[9] Its normal pattern is to scout a feeder from cover, fly in to take a seed, then fly back to cover to eat it.[citation needed]

Tufted titmice nest in a hole in a tree, either a natural cavity, a human-made nest box, or sometimes an old woodpecker nest.[10] They line the nest with soft materials, sometimes plucking hair from a live animal such as a dog.[11] If they find snake skin sheddings, they may incorporate pieces into their nest.[12] Eggs measure under 1 inch (2.5 centimetres) long and are white or cream-colored with brownish or purplish spots.[13]

The lifespan of the tufted titmouse is approximately 2.1 years, although it can live for more than ten years.[14] On average, these birds will have a clutch size of five to seven eggs.[15] Unlike many birds, the offspring of tufted titmice will often stay with their parents during the winter, and even after the first year of their life.[16] Sometimes, a bird born the year before will help its parents raise the next year's young.[17]
