Ron, it has been established that peregrines do migrate are night. (from a birding blog website) The question is: how many? Since migrating peregrine numbers are used to establish the peregrine harvest numbers in states permitting a passage harvest it is important to know how many more are passing the hawk watch stations, unseen.
