Pileated Woodpecker - Dryocopus pileatus

Numbers in eastern United States declined sharply in 18th and 19th centuries with clearing of eastern forest. Since about 1900, a gradual comeback, with the species becoming common again in some areas. May be adapting to second-growth woods and proximity of humans.  

This particular one is near the small feeder creek into the North East River near the Old Wharf,  now a private residence.  Snowy cold day for such a cheery looking bird.
