The last of 187 baby birds attacked at Lake Hefner died Wednesday night at a wildlife rescue center in Noble, the bird's caretaker said.
The cliff swallow's nest was among 30 to 40 that were knocked down — allegedly by an angry boat owner — Sunday at the Gate 4 docks of the Lake Hefner Marina, officials said.
The last survivor was rescued by Oklahoma City police Sgt. Lori Osborn and taken to the WildCare Foundation in Noble, where it died, director Rondi Large said.
The U.S. Fish and Wildlife Service is investigating the incident, but no arrests have been made and the name of the man accused has not been released. Cliff swallows are protected under federal law, making it illegal to harm them.
