Massachusetts - SLATY-BACKED GULL
The Connecticut River Valley's superb gulling continues. This SLATY-BACKED GULL was seen briefly last night at Turner's Falls, MA by James P. Smith and confirmed this evening by James and a handful of birders. As JPS initially suspected, this is the same individual found by Patrick Dugan in Windsor, CT on Feb 9th. Turner's Falls is about 50 miles north (up the Connecticut River) from the Windsor area. Fascinating stuff. Congrats to James for the state's first inland record and fourth overall.
Look to James' blog, Pioneer Birding, for more pics and info on his great find. He also saw the bird in Windsor and has photos posted there.
