Blue Tit (Parus caeruleus).
The Blue tit is the most common resident tit over most of Europe, especially in the west. They are typically woodland birds but have adapted well to living in close association with man. They are common, colourful, noisy, tame birds.Blue Tits nest in holes on trees or in walls but will readily use other, man-made objects. In Ireland at the moment, birds are nesting in several post-boxes and in traffic lights at busy junctions. Blue Tits seem to have benefited from the 'smoking ban'...many bars have erected wall mounted ash trays for their smoking customers and Blue Tits have discovered these.
