Parus Ater - Coal Tit
Source: British Garden Birds (www.garden-birds.co.uk)
The Coal Tit is a small tit, in fact the smallest European tit, and could be confused
with the almost indistinguishable Marsh Tit and Willow Tit if it was not for the white patch on the
nape. While it behaves like a Blue Tit, there is no
blue in its plumage.
Insects and conifer seeds are the Coal Tit's diet. In the garden, they choose black sunflower seeds, sunflower hearts, and occasionally suet. They store food, particularly when food is plentiful, for consumption later, albeit usually within a few days.
The high pitch song of the Coal Tit, a repetitive "pee-chew", is similar to that of the Great Tits but faster.
Breeding Coal Tits will nest in hollows in trees or in mouse holes. The nest is similar
to that of the Blue Tit (i.e. made from moss, wool, dead leaves and spiders' webs) except
that it is moss-lined.
