24–27 cm (9½-10½ in), weight 6-10 g
Very often will give the impression of a small fluffy circular ball with a long tail attached; more than half its length constitutes its 6-10 cm tail. Black and rosy-beige to greyish above and white below, with rosy-beige to greyish flanks. It has a white crown but different subspecies differs in amount of black in head. The different subspecies also differ in tail length, with northern populations having longer tails. The bill is very short.

Juvenile of all subspecies is darker and less glossy, with a broad dusky brown band through and behind the eye, and lacks rosy colours; right after fledging, the tail is also shorter.

Distribution

Europe and Asia but not in tropical areas.

Taxonomy

Silver-throated Tit was formerly included in this species.

Deciduous woodlands with undergrowth, scrub and other bushy habitats; also common in parks and gardens. Also wetland reed beds.

Behaviour

Flight

Flight is short, whirring bursts and drops. Looks like a bouncing ball of fluff with a tail. Usually in flocks playing follow-my-leader from one patch of cover to another. Seldom stays still for long, flitting about within a bush, chasing insects.

Breeding

Woven nests containing spiders' webs and lichen are built in a tree or shrub. Up to a dozen eggs per clutch.

Diet

Diet includes insects, spiders and (mainly in winter) small seeds. Increasingly often visiting bird feeders in gardens, even in urban areas.
