The Friends of Blackwater which assists the Blackwater National Wildlife Refuge in Cambridge, Maryland has two birdwatching cams for you: A bald eagle cam and an osprey cam. Currently the bald eagle nest has a nesting pair with two eggs and possibly a third on the way. The estimate hatch dates are Between February 28 and March 2. The osprey nest is currently unoccupied, but visitors do frequent the nest and you should expect a nesting pair in the spring. The bald eagle cam updates every 30 seconds and the osprey nest cam updates every 60 seconds.
