Larger groups of great and blue tits are better at solving problems than smaller ones, Oxford University scientists have found. The researchers believe that this is probably because the larger the group, the more chance there is of it including a 'bright' or 'experienced' bird that can solve a particular new problem: in this case operating lever-pulling devices to receive a food reward.
The study took place on wild populations of great tits (Parus major) and blue tits (Cyanistes caeruleus), which naturally flock together, in Oxford's Wytham Woods. A report of the research appears this week in Proceedings of the National Academy of Sciences.
