Article I read yesterday about how they breed peregrine falcons. I'd heard about this technique but never seen it (watch video).

ginger - I had never seen it, either, but there is a picture somewhere (Tribute video?) of Bob wearing the hat. ![Wink ;)](https://www.raptorresource.org/raptorresource/forum/Smileys/default/wink.gif)
T40 -- John Dingle told a story at Bob's celebration of life about Bob having John wear the hat. He told John what to do but I don't think he filled him in on exactly what would happen. Bob then grabbed the hat and rushed off to inseminate the female. It was a pretty funny story.
