INSUBCONTINENT EXCLUSIVE:
Birds can get intoxicated by eating fermented berries
(Representational)Police in Gilbert, Minnesota, are warning residents about a group of youthful residents unable to handle their alcohol
They've been drifting around town looking disoriented, narrowly avoiding getting hit by cars.But these aren't teenagers getting drunk
Instead, it's the local bird population."The Gilbert Police Department has received several reports of birds that appear to be 'under the
influence' flying into windows, cars and acting confused," Police Chief Ty Techar wrote in a statement Tuesday
An early frost meant that berries had fermented earlier than usual, he explained, and birds were eating them and getting drunk.Incidents
around town involving intoxicated birds appear to be more prevalent than in past years, Techar added, because many have not yet migrated
"It appears that some birds are getting a little more 'tipsy' than normal," he wrote
"Generally, younger birds' livers cannot handle the toxins as efficiently as more mature birds."He concluded: "There is no need to call law
enforcement about these birds as they should sober up within a short period of time."A number of Gilbert residents commented on the Facebook
post and thanked the police department for explaining why the birds had been acting so strangely
One woman wrote that she had found three dead birds on her deck recently, while another described quickly slamming on her brakes when a bird
flew directly into her windshield
" This explains why I have hit 7 birds with my car this week," commented another."I was going to say something
but I thought I was crazy!!!" wrote one resident
"This has been happening to me!" She added, " I know this post is a joke
2 birds dove into my windshield both on the way to work and on the way home
I was wondering what was going on."Another commenter joked, "There goes the chance of any bird from Northern MN ever being on the Supreme
Court."The police news release ended with a suggestion that residents of the small northern Minnesota town call if they see "Angry Birds
laughing and giggling uncontrollably and appearing to be happy" or "Tweety acting as if 10 feet tall and getting into confrontations with
cats."Jokes aside, however, birds really can get intoxicated by eating fermented berries
A group of California scientists who performed necropsies on several flocks of cedar waxwings that had collided with hard surfaces found
that all of them had recently gorged on overripe berries
"Flying under the influence of ethanol" had led to the birds' deaths, they concluded in a 2012 study published in the Journal of
Ornithology.Obviously, birds can't exactly take a breathalyzer test
Matthew Dodder, a self-described "bird guy" with four decades of birding experience who leads classes in Palo Alto, California, told The
Washington Post that the key giveaway to tell whether birds are drunk is their goofy behavior."They'll be flying kind of erratically," he
"We typically see them flying lower than usual through traffic
They're just careless and they're not looking for cars or other obstacles."Certain bird species, such as robins, cedar waxwings and
thrushes, are the most prone to drunken antics since they eat more berries than other species like warblers and flycatchers that primarily
And as they prepare to fly south for winter, they may overindulge in an attempt to store up fat for the journey, Dodder said
The birds go from bush to bush trying to find more berries, their balance getting progressively worse."They just get sloppy and clumsy,"
"They have actually fallen out of trees on occasion."In Portland, Oregon, the Audubon Society operates what's essentially a drunk tank for
"We get in birds into our Wildlife Care Center in the fall that are drunk on fermenting berries," Bob Sallinger, the conservation director
for the Audubon Society of Portland, wrote in an email
"Sometimes they are picked up after crashing into windows
Others are just found disoriented on the ground
We will hold them in captivity until they sober up and then set them free."The same thing happens in Canada's Yukon Territory, where animal
welfare officials will gently place intoxicated birds in small hamster cages until they're ready to fly again a few hours later.As humorous
as it might sound, bingeing on berries can be deadly for birds
Portland has seen multiple incidents in the past decade where between 30 and 50 robins have suddenly turned up dead due to suspected alcohol
