Those of you who receive Maryland eBird alerts or use the 
Maryland eBird Google gadget may have noticed an unconfirmed 
report from another birder of a Wilson's Plover today (Sunday) at 
the landfill pond at Blue Mash nature trail (Montgomery County).  
I wanted to post to caution people about traveling to try to see 
the bird for two reasons:

(i) the bird in question has not been subsequently seen to my 
knowledge.  I arrived at Blue Mash when the birder who reported 
the bird was leaving.  I checked the pond and there were no 
plovers of any kind -- not even Killdeer.  Apparently they had 
recently left.  So I was unable to confirm or disconfirm the 
report.  I checked again this evening and there was only a 
Killdeer together with the Pectoral Sandpipers, Lesser Yellowlegs, 
and peeps that had been there earlier (together with a couple of 
Green-winged Teal).

(ii) I do not know the birder who reported the bird, but for 
obvious reasons there will be skepticism about such a report 
without a photograph.  The recent passage of a hurricane does make 
at least the timing seem intriguing, though.

Good birding!
