A cormorant cruises along the top of the Cocheco Falls dam in downtown Dover, New Hampshire.Upstream, another watches for migrating fish.
When the river herring run from the sea into freshwater streams to spawn a new generation, the cormorants tag along, along with a cloud of fishermen.
The herring, which include the alewife variety, are part of New England lore. Look closely here and you’ll see them crowded in under the shade along the river.
River herring rest in a pool along the Charles River in Massachusetts.

I love the way cormorants swim with their bodies just below the surface. They always make me think of submarines. Thank you for the lovely photos!
