Okay, first my thanks to all of the replies so falots of info to sort through. Second, I need to make a point of clarification. 😃 with Chimny Swifts, I ment cling not perch. I have seen them cling to sides of dams before but my camera lens wasn't good enough to reach them then, so I was hoping someone would know of a good place to look. ______________________________________________________________________ Ohio-birds mailing list, a service of the Ohio Ornithological Society.
