Saw a breeding plumage Forster's Tern this afternoon at Triadelphia Reservoir.  
Initially saw the tern flying over the reservoir near the Greenbridge boat ramp 
when I was on the Brighton Dam.  After going to the Greenbridge boat ramp 
the tern was relocated sitting on a buoy.   Two Ring-billed Gulls were also present.
