The Eurasian Blue Tit (Cyanistes caeruleus)

The Eurasian Blue Tit (Cyanistes caeruleus) is a small, vibrant bird common across Europe and western Asia. Recognizable by its bright blue crown, wings, and tail, with a yellow underbelly and a distinctive black stripe across its eyes, it measures around 12 centimeters long. These energetic birds are intelligent and agile, often seen flitting among trees and feeding on insects, seeds, and berries. They are social, forming noisy, lively groups especially outside the breeding season. Blue Tits are adaptive nesters, often using tree holes or nest boxes, and play a vital role in controlling insect populations.
