Researchers at Oxford University have been studying the Wytham Woods great tit population in Oxfordshire for 70 years and so the team had access to a wealth of historical data which clearly showed that the British great tits' beaks were getting longer over time. Once feathers begin to erupt, the nestlings are unusual for altricial birds in having plumage coloured with carotenoids similar to their parents in most species it is dun-coloured to avoid predation.

Tits also have a variety of methods for attracting mates, primarily through their intricate, bouncing mating dance. Species relationships based on sequences of the mitochondrial cytochrome-b gene".

Still, the interrelationship of these, as well as the relationships of many species within the clades, are not well-resolved at all; analysis of morphology and biogeography probably gives a more robust picture than the available molecular data.

How birds' beaks evolved characteristic shapes to eat different food is a classic example of evolution by natural selection. They were also able to access data from electronic tags fitted to some of the Wytham Woods birds, which enabled them to track how much time was spent at automated bird feeders. Archived from the original PDF on 11 October Retrieved November 25, This made the scientists wonder if there are measurable differences between beak length in the two populations—and sure enough, there were.

Great tits are cavity nesters, breeding in a hole that is usually inside a tree, although occasionally in a wall or rock face, and they will readily take to nest boxes.
