Thousands of birds dead or injured
Thousands of migratory birds are dead or injured after they apparently mistook a Wal-Mart car park, football fields, roads and other areas of southern Utah for bodies of water and plummeted to the ground.
One wildlife expert in the US state called it the worst downing she had ever seen.
Crews went to work cleaning up the dead birds and rescuing the injured survivors after they crash-landed in the St George area.
By midday Wednesday, volunteers had helped rescue more than 3,000 birds, releasing them into a nearby pond. There is no total on how many died, although officials estimate it is more than 1,500.
Wildlife officials said stormy conditions probably confused the flock of eared grebes, making their way to the Mexican coast for the winter.
