The Coal Tit is essentially a resident that survives the winter in the Swedish coniferous forest, but the population can shift considerably in some years.
Food: it lives on hoarded spruce seeds and insects that it has hidden during the autumn in bark crevices, among needles and in lichens.
Flocks: it readily roams high up in the spruce tops, often in the company of Great Tit, Goldcrest and other tits.
Irruptions: in years with poor seed supply large flocks move south and west and then turn up in gardens and at bird tables, where they take sunflower seeds and peanuts.
