The Eurasian blue tit is a small passerine bird. It is easily recognisable by its blue and yellow plumage and small size. It is soft, friendly and round. The Eurasian blue tit prefers insects and spiders for its diet. Outside the breeding season, they also eat seeds and other vegetable-based foods. The birds are famed for their acrobatic skills, as they can hold on to the outermost branches of trees and shrubs and hang upside down when looking for food.
