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. The titmouse can demonstrate curiosity regarding humans, and will sometimes perch on a window ledge and seem to be peering into the house. It is a regular visitor around bird feeders. Its normal pattern is to scout a feeder from cover, fly in to take a seed, then fly back to cover to eat it.
