Vets in Sundsvall, Sweden, believed they had a case of avian influenza when they discovered a seagull with "with yellow liquid coming out of its beak and anus", crashed out on its back and "kicking its legs", UPI reports.

The truth was rather less alarming - the bird was actually the worse for wear after apparently eating yeast on a rubbish dump. Tests confirmed its state of intoxication and the vets rather unsportingly put the poor blighter down. ®
