Hi Rich,

Next time you are at RFK keep you eyes on the look out for Peregrines.  About 20 years ago I saw a pair of Peregrines copulating on the goal posts during a concert.  Unlike your osprey, they did not seem to by bothered by the thousands of people.  Isn't it fun to bird where and when it is least expected?

Naturally,
