Perhaps 20 to 30 years ago, one of the leaders of the Twin Cities raptor community (Bud Tordoff, I believe) presented a program about Peregrine Falcons to a downtown St. Paul firm where my wife was employed. He stated that the most common prey species identified at the nest box on the Bremer Building was Yellow-billed Cuckoo. (Who would have guessed?) Maybe the cuckoos you've found were also "peregrine leavings." Julian
