Animal rescue groups in the United Kingdom have reported that they have seen a high number of cases of drunk seagulls in recent weeks.
RSPCA officers in Somerset have been responding to a number of calls regarding gulls seemingly suffering from the effects of alcohol.
Other sources report that the seagulls' freakish behaviour could be nothing to do with alcohol, but instead the consumption of flying ants which produce formic acid, a substance that "stupefies" the birds.
The RSPCA is urging local breweries and distilleries to check waste is secure and that wildlife can not get to it.
The animal welfare charity is now urging local breweries, distilleries and alcohol producers to check that their waste is secure. It advised vets coming across gulls with beer symptoms to give them a chance to sleep it off.
The RSPCA have said they have treated a number of birds in recent weeks and they have even obtained some footage displaying the birds erratic behaviour.
It added that brewery waste can also be used as compost and feed so narrowing down how the gull's are being affected has been hard.
One bird was rescued at Lyme Regis, Dorset, after he drank alcohol on the beach.
The RSPCA said some of the birds had died, while others went on to recover.
RSPCA Inspector Jo Daniel, who has been rescuing the birds with colleagues Clara Scully and Paul Adams along a stretch of coast from Dorset to Devon, said: "The birds absolutely stink of alcohol when we collect them so now our vans smell like pubs".
