Juvenile Parus major (great tit) scrapping with a very feisty juvenile Cyanistes caeruleus (blue tit) on a garden peanut feeder. Forest of Dean, Gloucestershire, UK.The baby blue tits are really funny as they are far more bolshy than the parents. They often fought off the great tits whilst trying to feed, with what you couldn't help feeling was some degree of consternation from the larger birds.
