Fooled Pelicans

Brown pelicans crashing into pavement, mistaking it for water

The heat-induced shimmer of Arizona's pavement is fooling the brown pelican population. State officials report more than 30 of the endangered birds have crashed into paved surfaces that they've mistaken for lakes and creeks.

The state's Department of Game and Fish says the injured birds have been found from Yuma to Phoenix over the past two weeks. The pelicans are being treated for dehydration and malnutrition.

Experts believe the birds are heading to Arizona to look for fish because of a food shortage along the West Coast.

The combination of the sun's reflection on the pavement and hot and cool layers of air can create the illusion of water.
