The main food is native tree buds, oak, sallow and hawthorn are all eaten with their taste for fruit buds being their undoing. Indeed the damage inflicted on commercial fruit crops gave the bird the status of an agricultural pest, this giving rise to their culling! They also eat soft fruits and seeds and you can see on the photo`s that their beaks are covered in the rowan berries they have been happily munching on.
There has also been a loss of hedgerows with standard trees and agricultural intensification which are both thought to have helped the decline in numbers.
