Pileated Woodpecker (Dryocopus pileatus), Drumming
He found an old electrical pole with nice acoustic properties. You can hear his rapid drumming a long way away! 8:38:43 am, after I figure out how to take clear photos. Let me know if you want to see the whole drumming sequence: I have 31 photos taken within 2 seconds. 1/2500 sec, f/4.0, ISO 1000.
