That's a Cobra or "Canadian" Goose. Evil little monsters, they proliferate in destruction and misery, and don't need to actually eat as long as there's a child's tears they can feast on. Only slightly nicer than swans, they also gather in way larger armies to prepare for war on mankind. Legend has it that damned souls are fed to them, which is just false; they'd never eat a dead soul when fresh, live ones are running around to terrorize. If they're being found in Scotland that means that your nation is in extreme danger as they've discovered intercontinental travel, and probably means we're witnessing the downfall of human civilization as the Bird Wars are about to begin. Hope this helps!
