The Red-throated Loon reported by Jim Green and found by Kyle Carstensen,  
Dave Young and Jim, was still at Riley's Lock at 4:15 PM.
 
When I drove in, the loon was 100 yards up Seneca Creek, actively  feeding. 
 Good views from the road.  I went up on the aqueduct and  proceeded up the 
tow path, observing seven ruddy ducks, seven scaup (sp.) in the  Potomac, 
and eight bluebirds along the bank of the river.
 
When I returned, the loon was very close to the aqueduct, and called three  
times.  It was so close, I could not see it and the calls reverberated off  
the bridge.  Most exciting!
 
I proceeded over the little bridge and there was the loon, right below me,  
perhaps 30 feet away, affording exceptional looks at this out of habitat  
bird.  Best looks by far in Maryland.
