It's sad, actually.
Birds might not be better than us after all. They have fancy hollow bones and the gift of graceful flight, but in the sense that we are all just floating around looking for fermented berries, there is existential parity.
The Veterinary Record of the British Medical Journal tells of a young bird in Cumbria, found outside of a primary school, that was visibly impaired, hobbling around. Staff at a wildlife rescue center described it as "unsteady on
its feet ... [It] placed both wings on the ground to support itself and lent against
the walls of the enclosure to maintain posture 'as though it was drunk.'"
Around it, twelve other blackbirds -- precisely half of four and twenty -- were found dead.
Avian pathologists disassembled the birds to see what went wrong. Inside they found rowan berries that had "a faint odor of fermentation" -- enough to smell it while dissecting dead birds, at least. A biopsy of one of their livers had an alcohol level of 430 parts per million. Levels of 238 have been implicated in fatal ethanol intoxication in the past, in two poor wild cedar waxwings.
The surviving bird made a full recovery; back to normal by the next day.
