Jones Beach West End

I checked out the west end around the median and thought I was seeing/ hearing Acadian Flycatchers at first but they were Willow Flycatchers and I believe I saw 4 of them. (they were moving around a lot). I came back later in the morning to see what was in the ponds- there was a sandpiper that stood out from the rest because it was plumper and had a reddish tinge to it.  We thought it could be a Western but another birder said it was a White Rumped (from Whats This Bird). I saw the continuing Pectoral again so I was happy about that.  Not much going on at the Coast Guard area except Sanderlings and 4 continuing Black Scoters.
