Officials say at least 16 oily birds, seven turtles, nine reptiles, a beaver and a muskrat have been recovered for treatment since an Exxon Mobil pipeline ruptured last week in central Arkansas.
Authorities are urging people not to touch any injured or oiled animals as crews clean up Friday's spill in Mayflower, a small town about 20 miles northwest of Little Rock.
Crews have also recovered thousands of barrels of oil and water since an Exxon Mobil pipeline sprung a leak and spewed oil onto lawns and roadways.
Seven ducks have also been found dead. Exxon Mobil says a contractor has started a wildlife rehabilitation operation on-site.
