Wildlife officials are warning people to be on alert for drunk birds.

Yes. Drunk birds.

In a Facebook post, the Wildlife Resources Division of the Georgia Department of Natural Resources said fruit-eating birds such as cedar waxwings and American robins often eat fruit that has started to rot and ferment. A byproduct of fermentation is the production of alcohol and, when consumed, the result can be drunk birds.

“The consumption of these fermented fruits can cause the birds to lose much of their coordination and capacity to fly. This can cause them to crash into windows and other obstacles. Sadly, they can also die directly from alcohol poisoning if they ingest enough of the fermented fruit,” the agency said in a Facebook post.

Another possible cause for drunken flying is when birds have eaten Nandina, or sacred bamboo, berries. This exotic invasive plant is used in landscaping and draws cyanide from the soil, depositing often lethal doses in its bright red fruit.
