Hanging on top of a tree or a twig, the Eurasian blue tit eats small insects, larvae, caterpillars, spiders and invertebrates. Once the branch is cleaned, the Eurasian blue tit moves on to the next one. Occasionally, it can eat fruits and seeds. The female nests in holes of trees or walls. It broods 7 to 13 eggs for 15 days while the male feeds. The chicks will be entirely dependent on their parents their first month of life.
