Hello,

There is at least one nest of YCNH in Sligo Creek Park this year.  You can
see it from the bike path, between Wayne Ave and Piney Branch.  It is
actually about halfway between Wayne and the bridge over the creek, on a
tree on the east side of Sligo Creek Parkway, on a tree overhanging the
parkway.  Click on this link for a map
