Scientists are racing against time to help save marine birds and other wildlife affected by the oil. National Wildlife Federation naturalist David Mizejewski describes the pelicans and turtles he's seen in the Gulf. And, the Kemp's Ridley sea turtle feeds and nests right in the path of the Gulf oil slick. So dependent on this stretch of coast for survival, this endangered sea turtle is particularly vulnerable to the effects of the spill. Host Jeff Young talks with Pat Burchfield, a scientist at Gladys Porter Zoo in Brownsville, Texas, who has studied the turtle for nearly four decades.
