Invisible Birds

A man walking along the sidewalk was stopped by a clamor above him. Staring up into the tree branches, where a deafening blast of bird chatter sounded, the man strained to see what was the deal, but could see nothing other than the dense leaves. Just then, a jogger came pounding past, and, without looking up or to the side, the jogger quipped, “There’s a few of them up there, yah think?”
