Saw this one hammering the old oak, so I'm guessing it's a #woodpecker of some kind. Anyone know #birds well enough to identify? Location: northern #NewJersey
Red-bellied Woodpecker Overview, All About Birds, Cornell Lab of Ornithology

Red-bellied Woodpeckers are pale, medium-sized woodpeckers common in forests of the East. Their strikingly barred backs and gleaming red caps make them an unforgettable sight – just resist the temptation to call them Red-headed Woodpeckers, a somewhat rarer species that's mostly black on the back with big white wing patches. Learn the Red-bellied's rolling call and you’ll notice these birds everywhere.

@jimr I believe it to be a red bellied woodpecker (though ironically it’s the back of his neck, not his belly that is red.)
