I went to Schoolhouse Pond last night (Friday 16) and saw no Moorhen.  It was actually VERY quiet, birdwise, and very still and very hot, weatherwise.  Since I also did not locate any Wood Duck, and the Moorhen has been reported to hang with the Wood Duck, I thought I'd try again this AM (Saturday).  
 
I arrived at the Pond around 10:30 AM and spent 1 1/2 hours carefully looking everywhere I could.  I was able to locate many Wood Duck, but no Moorhen at all.  The consolation bird was a wonderful Little Blue Heron.  
 
If anyone sees this Moorhen, please post. I'd like to try again, but need some incentive.  
 
I'll also be trying for the Sandhill Crane tomorrow afternoon.  I think that means that those of you who want to see him better get out this afternoon and tomorrow morning - before he flies off to elude me!  (No, it's not really that bad - I do catch a few chases, now and again!)
