I lead a trip for MBC to Black Hill RP. We found a total of 40 species. 
List below. Highlights being a male Northern Shoveler along the rip rap 
near the boat ramp and a pair of Bald Eagles in the big tree near the 
Rt.121 cove.  We observed the bald eagles copulate (or attempt to). 
After which, Clair Wolfe observed one of the eagles fly to the ground 
and pick up some grass and fly off towards the dam before we lost sight. 
Nesting material? The Ten Mile Crk area was very slow.  Missing were Am 
Wigeons and Canvasbacks, I had seen earlier in the week.  We walked the 
Turkey Hill and  Lake View loops in the Ten Mile Crk area but landbirds 
were few and far between.
