Original observer: Howard Payne. Source: Royal Ontario Museuem, Toronto, specimen #27096 collection tags. In the summer of 1936, exact date not known, Howard Payne collected three young birds from an eyrie located on Fairy Lake. At least one of the birds was taken alive and donated to Don MacKinnon on 26 July 1936 (the date used for this eBird record). He kept the bird alive for almost a year, but it died in his possession on 11 May 1937 and was later donated to the Royal Ontario Museum. A partial skeleton and the skull were preserved. A number of historical breeding sites have been documented in Muskoka, including Crown Island, Devil's Face (an 80 foot high cliff) on Skeleton Lake, Honey Harbour, Port Sydney, Echo Rock (a high escarpment) on Solitaire Lake, Fairy Lake, and at least two different sites on Lake of Bays. The Devil's Face on Skeleton Lake was an active nest site for at least 80 years, with a pair of Peregrines using it until 1962. The following year a pair of Common Ravens took up residence (Mills 1981). Historically this falcon nested on cliffs in remote areas near water and in forested areas (Sandilands 2005). It was eradicated as a breeder in Ontario by 1963 because of the effects of DDT and other pesticides. Nesting reoccurred in Ontario in 1986, and the present cliff breeding range is similar to the known historical range, but there are noticeable exceptions, particularly in the southern Shield Region, where the known range has not been reoccupied (Armstrong 2007 Ontario Breeding Bird Atlas).
