I was down in Woodside Park in Essex today and it was extremely buggy.  Ran
into Steve who felt the same.  On the part of the trail near the Winooski by
the small pond I observed a medium sized yellow bird fly onto a branch about
25 feet up.  It had a large bug in its bill which was slightly curved
downward.  I observed darker wings with white wingbars.  I saw no trace of
orange, it was definitely yellow, with light yellow extending from the belly
underneath the tail.
Flying around this bird was what I initally thought was a Robin, but what
struck me was the extremely dark, almost burgundy belly.  I did not get a
great view.  He was very dark on his back and tail, and coupled with the
very dark burgundy breast could *possibly* be a male Orchard.
So, in summary, very confident in female Orchard and possible male Orchard.
Steve, if you want more info on exactly where to look for a possible nest,
let me know.
