Voice

The Blue Tit’s song is “tsee-tsee-tsu-hu-hu-hu-hu” and can be heard all year round. Their alarm call is a churring noise.

Feeding

They feed mostly on insects, especially caterpillars, and seeds. In spring they also feed on pollen, nectar and sap, and autumn its berries.

In our gardens they look around the plants and any crannies for insects like aphids, beetles, and caterpillars plus spiders, but also like sunflower hearts or high energy seed from feeders, or nibble at a suet food bar or peanuts.

They are most agile birds, and they will entertain for hours by hanging upside down from anything that takes their fancy. They also and will often peck through foil milk bottle tops for the cream.

Blue Tits, and other tit species also peck putty around windows, usually at winter time. Some may simply be hungry and attracted to the linseed oil in the putty, though it is thought more likely that they are simply searching for food. But double glazing is slowly putting an end to this.

Nesting

Blue Tits will nest in any hole in a tree, wall or nest box. They are known for nesting in more unusual places, such as letter boxes, pipes, etc. The nest is a cup made by the female from moss, wool, dead leaves, spiders’ webs, and lined with down.

Their clutch size is the largest among nidicolous species, laying around 10 to 12 eggs. The eggs are laid at such a time that green caterpillars will be abundant when the chicks hatch. Second clutches are very rare.

The eggs are smooth and glossy, and white with purplish-red or reddish-brown spots. They are about 16 mm by 12 mm. The female incubates the eggs by herself. After the young hatch, they are fed by both parents.

Please encourage blue tits by placing nest boxes in your garden, you can even buy cameras to place inside, the pleasure is well worth the expense.
