Brightly-colored inhabitant of wooded and forested habitats, parks, gardens, and hedges in farmland. Plumage distinctive, with blue cap, white face with dark line through eyes, yellow underparts. Smaller and more active than Great Tit, which often occurs alongside Eurasian Blue Tit but has a very different head pattern, different calls. Juvenile (seen in summer–early autumn) has yellowish wash to face, drabber plumage overall. Often visits bird feeders and uses nest boxes. Listen for variable high-pitched vocalizations, as well as harsh scolding calls.
