What happened

NTSB summary, verbatim

During the approach to land, the flight crew reported a bird strike to the leading edge of the right wing. The crew declared an emergency and made an uneventful landing at their destination. A postaccident examination of the airplane revealed a 12-inch-diameter hole in the leading edge of the right wing centered between the right engine nacelle and the right wing tip. The damaged area was covered in bird remains, which were identified as the remains of a Common Loon (Gavia immer). The average weight for the species is about 10.9 pounds.
