They'll stay in an area about 15 to 20 acres. In the late winter to early spring, the flock will break-up into pairs and lone birds. Though flocks are formed, Tufted Titmice don't migrate. They mate around the break-up time. The longest recorded pair stayed together for three years.
Couples can form at any time.
These birds live up to 13 years. Tuffy's Rescue Tuffy was still immature when we found him plastered into a couple glue traps in my barn. It took us an hour and a half to get that poor bird out of the sticky contraption, leaving his feet last and keeping a good hold on his head. Soon enough the thing got free and tried to attack us, unsuccessfully with his beak. The next day, in a box, I took the ragged animal to my science teacher.
