Had a very brief look at a Sora this morning (about 7:35) at Hughes 
Hollow in same location reported by Dave Powell on 4/8.  It was at the 
waterline next to a brown rusty pipe (just beyond the bulletin board).  
Got down on the ground to try and look underneath the bush on the far 
side of the pipe but could not spot it again.
