Feeding Blue tit (Cyanistes caeruleus) by hand.

Girl feeding wild blue tits on a cold winters day in a Park in Warsaw, Poland.

The Bule tit’s colourful mix of blue, yellow, white and green make it one of the most attractive resident garden birds. Almost any garden with a peanut feeder will attract them and they readily breed in nestboxes. In winter they form flocks with other tit species and a garden with four or five at a bird table at any one time, may be feeding 20 or more.
