The small American town of Gilbert, Minnesota, faced an ornithological enigma last month. For over a week, the town’s birds, especially robins and other small species, acted erratically, crashing into windows and car windshields and “flopping all over the place”. The police chief investigated and ended up sending a notice to residents telling them there was no need to call the police on the “inebriated” local birds because they had simply gotten themselves intoxicated on berries that fermented as a result of an early frost... Mystery solved!
