Our intrepid team of observers (Tracy Holmes and Bill Clark) discovered that the GBBG blamed for stealing eggs from neighboring nests, was actually a Herring Gull.
Here’s the scoop from Tracy Holmes:
RABA (AOU code for “Rat Bastard”) is a Herring Gull! Attorneys from the Great Black-backed Gull Union contacted the island last week to inform them a suit for defamation of character and slander had been filed in Superior Court in Augusta, Maine. A mediator has been retained and hopes for an out of court settlement remain strong.
Below, a photo of the true culprit and its larcenous repast:
Thanks for the clarification, Tracy!
