We hurried along to the next platform along shore and found a close view of a seemingly thoroughly exhausted Glossy and a Birder/photographer who reported he had seen the struggle from the beginning. He told us that a turtle had a hold of the leg of the Glossy and he had been watching the Glossy battle to survive for about an hour. John Heinz NWR, Tinicum, PA. 8/19/12.
