The Eurasian Blue Tit is distributed throughout most of Europe and into the Middle East. See the distribution map at Birdlife International. It is found in deciduous or mixed woodland, parks and gardens provided that suitable nest holes are available. Nest sites are typically a hole in a tree or a wall.

It has a small, rounded head without an obvious neck. The crown is blue on a white head which also has a black stripe through the eye. Underparts are yellow with a narrow grey stripe in the centre of the belly.
