Fall for the Red breasted Nuthatch?

A spate of Red breasted Nuthatches were reported today with Greenwood cemetery hosting the numbers. Linda Ewing spotted a small flock in the Cemetery at Pine Hill; a later report on ebird submitted by A.Romani mentioned three together in GWC. Several Brooklyn coastal locales also had singles of RBNuthatches. Could an irruption be in the m making? We'll see in the fall.
