Yellow-bellied Sapsucker on the Make!
I learned that this woodpecker was seeking a mate. He startled me with his cat-like, high-pitched, very loud caterwauling! He hit the sign just as loudly, unafraid of me. I learned sapsuckers hit signs like this — and the brighter the sign the better — to attract females. I was wearing bright colors that morning as well. His noise making and following me around that morning made for great advertising.
