The first chilly days of October see birds piling back into gardens. Amongst the crowd is the diminutive Coal Tit, which has a special way of making the most of your garden offerings.
Coal Tits have a light-weight appearance, being slightly smaller than Blue Tits. They have a black and white streaked head, which includes a black bib, white cheeks, black cap and white patch on the back of the head, the latter feature is especially useful for identification purposes. Coal Tits have olive-grey upper-parts with two white wing bars (the only tit species to show this feature) and white-buff under-parts. The overall appearance is akin to a smaller, drabber cousin of the Great Tit.
Coal Tits are inconspicuous garden birds which are less showy than many of their cousins, such as Blue and Great Tits. Coal Tits can hop into a garden, grab a seed and disappear again largely unnoticed and they are one of a select group of garden birds that, during autumn, cache their food for leaner times ahead. Look out for Coal Tits alighting onto a garden feeder, grabbing a tasty morsel and then flying away to store it. Caches are typically located a few metres above the ground but can also be placed in the ground. By caching garden offerings during October, Coal Tits guarantee themselves a more reliable supply of food during the months ahead.
In October many Coal Tits often appear in mixed-species flocks alongside other tit species. The number of Coal Tits that come into gardens each autumn varies annually depending, in large part, on food availability in the wider countryside. Research using data from the British Trust for Ornithology (BTO) Garden BirdWatch shows that when natural foods, such as Sitka Spruce seed, are abundant, fewer Coal Tits come into gardens.
Feeding preferences
Coal Tits have a fine beak that is adept at handling many foods. At Garden Feeding Stations, wild bird food such as seeds and peanuts are a particular favourite and both may be cached during autumn. Suet-based bird foods are also eaten. Sunflower Hearts in a Seed Feeder are a favourite.
