A familiar sight along the harbor and around our many ponds, Ospreys are a common site as they dive for fish across the island. Ospreys (Pandion haliaetus) are iconic on-island, a part of our maritime community. Also known as Fish Hawks, they are abundant on Nantucket this time of year, having migrated back this way in late March. While these majestic birds of prey are now a fixture of early spring and summer on the island, that was not always the case.
