The Bull Finch’s voluptuous pink breast and white rump make it one of the easiest birds to identify, but for many birdwatchers its call, a low mew, is often the first signs of bullfinches being present.
They feed voraciously on the buds of fruit trees in orchards which why they are sometimes called Bud Finch, Plum Birds or Bud Pickers (Devon). There is a theory that the name Bull Finch may be a shortening of Bullace Finch. (Bullace being the Tudor name for the wild plum trees that were cultivated in medieval orchards).
The more widely believed theory is that Bullfinch got its name from its large thick head and stocky form, as happened with bull dog and bull frog. Some birdwatchers claim to have seen the birds head-butt other finches off the bird table. Other folk names include Alpe, Nope, Pope and Monk.
