The blue titmouse is very recognized in Europe. He can e found in backyards all over Europe. This has made him a popular bird.

This bright blue and yellow bird can be found in forests of older and younger trees in Europe. An old forest is used for nesting, because the holes in the trees are large enough for their nest. They are a sociable bird, and have been known to combine flocks in search of food.

In spring and summer caterpillars are not safe, because blue tits favor these as a hardy meal. In fall they become more of a vegetarian by consuming elderberries, hawthorn berries and seeds. In winter, the blue titmouse must search for food more vigorously, and many survive that would otherwise die because humans feed them with nuts and scraps.

The breeding season for the Blue titmouse begins in April. The male and female will begin to search for a nesting site in February. The male shows the female several nest sites, she has the final say. She will choose one and she will build the nest on her own. When the nest is built she will lay up to thirteen eggs. While the female is laying and incubating the eggs, the male will defend the nest and the territory around their food supply.

The eggs will hatch during May or June when food is plentiful. Their young will stay in the nest for two to three weeks. They will be fed by the parents, the caterpillar will also be its meal. The chicks at six weeks will have their feathers, they are the same coloring as the adults but duller. The lifespan of a blue titmouse is an average of ten years.

There is not known to be any real threat to the Blue Titmouse: there are approximately four million breeding pairs.
