When birds fall out of the sky, people think the worst—apocalypse, environmental catastrophe, mass bird protest. Sometimes, though, the birds are just drunk.

That’s what happened yesterday in Austria, where a whole flock of starlings guzzled down fermented berries and then decided to mess with some drivers. Soon, they were divebombing the A2 motorway, crashing into cars and trucks and causing miles-long traffic jams, The Local reports.

This happens to birds surprisingly often, especially in the fall, as freezing and thawing cycles turn berry juice into alcohol. “Most birds likely just get a bit tipsy,” Meghan Larivee, a scientist with Canada’s Environment Yukon, told National Geographic in 2014 after an incident with some hammered waxwings. “However, every now and then, some birds just overdo it.”

In those cases, she says, “They cannot coordinate their flight movements properly or at all.” But they probably think they’re doing awesome.
