Drove behind Fremont's water filtration plant, where warm outlet stream 
flows into Sandusky River. Several hundred Mallards with a sprinkling of 
Black Ducks were feeding on the thousands of shiners in the open water. Two 
adult Bald Eagles flew from their nearby perch and swooped over the large, 
concentrated flock of ducks. The ducks didn't fly into the air, but rapidly 
skirted away, paddling away. The eagles never touched the water and 
immediately flew back to their perch high atop a nearby tree. I wonder why 
they didn't follow through on the attack and talon a duck. Maybe looking 
for old, unhealthy or sick prey? Observed this behavior for a half hour. 
Sixty additional Mallards landed in the 30 ft. wide by 250 ft. long open 
stretch of water. There were over 300 Mallards and a dozen or so Black 
Ducks feeding when I left. An interesting interaction! Robert
