Yesterday, Lady Hillary and I were scouting launch points along the Passaic River in Chatham, NJ. We heard an unusual bird call and, using herself's SmartPhone, we were able to identify the call as a red bellied woodpecker. The environment was right, with a lot of dead trees but we were well North of its usual range.
We never did eyeball the bird but the call was loud and distinctive.
I was able to verify it on line.
Do you think this is simply a bird that got off course or a function of global warming?
