We rode at Blackwater National Wildlife Refuge on Sunday. It's sort of cheating to reply here with the critter count, but this is what we saw:

3 bald eagles
10 turtles
1 nutria
1 fox
2 deer
lots of great blue herons
lots of egrets
lots of ducks
a gajillion geese - Canada & snow geese
1 cat
1 grasshopper

And we heard osprey but couldn't find them.
