When it happens, we call it a roadstrike. It's a very serious situation that happens to water birds, usually loons or grebes, who cannot take flight without first running on top of the water to gain speed. Roadstrikes occur when these birds mistake the wet surface of a road or parking lot for the shimmering surface of a body of water. They come in for a landing, often injuring themselves during the unexpectedly-hard touchdown, and then they're stranded. Without human intervention, they usually don't have long before they move from the category of roadstrike to roadkill. Thankfully, that was not to be the fate of a Pied-billed Grebe who crashed down near the Woodland Park Zoo in Seattle.
