If the pure breds are anatums and Peales and they are the subspecies that occur locally then it's not a threat, just an addition. I have been a falconer since 1963 been on the executive on a few different clubs and personally know or know of 99% of the falconers in B.C, Alta, Sask, and quite a few of the WA state guys. I know of no cross bred peregrines being flown in B.C. for at least 10 years maybe more, nobody buys crosses when pure birds are so easy to come by. There are no Tundras, Cassini's, Fiji or other peregrines being flown in B.C. at the present time or for a long time.
The current "in" bird for falcons is the Gyr hybrid so really not many peregrines are being flown anyway.

How is a "pure bred" bird not a threat to the gene pool when the subspecies is inapropriate for the region where the bird escapes? And how do you know that the birds were "pure breds"?
