A great day's start when you see a COOPER'S HAWK fly down Prospect Park Southwest Avenue.At about 6:50 am,as I crossed over to the park for the Windsor Ave/16th St entrance, the COOPERS appeared out of the park at that area, and the accipiter cruised quickly down the street a mere 50 feet above. It continued all the way to Vanderbilt Street where I presumed it flew over the tenements. What birder couldnt ask for more than that experience?
