The lifespan of the Tufted Titmouse is approximately 2.1 years, although it can live for more than ten years. On average, these birds will have a clutch size of five to seven eggs. 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. Sometimes, a bird born the year before will help its parents raise the next year’s young.
Their breeding habitat is mixed or deciduous woods in the United States from New Jersey west to southern Kansas and south to Florida and Texas; there is a gap in the range at high altitudes in the Appalachian Mountains where they are replaced by their otherwise more northern relative, the black-capped chickadee. They nest in a hole in a tree; the pair excavates the nest, using a natural cavity or sometimes an old woodpecker nest. They may interbreed with black-capped chickadees where the ranges overlap, which can make identification difficult. They are permanent residents, not usually moving south even in severe winter weather.
