Thousands of birds have died after mistaking the parking lot of a Utah Walmart store for an expanse of water. The grebes are believed to have flown head-first into the parking lot at fast enough speeds to die.
Aroun 2,000 birds were saved, while many more died. They didn’t all hit the parking lot. Some apparently hit other nearby buildings and sidewalks, suggesting that the flock got well and truly lost.
The incident isn’t actually that unusual, as birds can often be tricked by manmade objects. It’s believed that a combination of storm clouds over the area and local street lighting combined to trick the birds on this occasion.
