Coal tit Not as colourful as some of its relatives, the coal tit has a distinctive grey back, black cap, and white patch at the back of its neck. Its smaller, more slender bill than blue or great tits means it can feed more successfully in conifers. A regular visitor to most peanut feeders, they will take and store food for eating later. In winter they join with other tits to form flocks which roam through woodlands and gardens in search of food.
