ROBERT, La. (AP) — Federal officials responding to a massive oil spill in the Gulf of Mexico say no dead, oiled birds have been found in Texas.

U.S. Fish and Wildlife Service spokeswoman Nancy Brown said Monday that an official tally released Sunday was incorrect. She blamed the mistake on a clerical error made while compiling figures from different states.

A new report on wildlife harmed by the oil spill will be released later Monday.

Texas General Land Office spokesman Jim Suydam (SOO'-dam) says there were no reports of oiled birds in Texas. He says the spill's westernmost limit is about 100 miles east of the Texas-Louisiana border.

The April 20 explosion of the Deepwater Horizon rig off Louisiana triggered the worst oil spill in U.S. history.
