Derek Canning's peregrine falcon breeding project after 16 years enforced retirement 

I secured four female peregrines falcons that people had tried to breed from over many years and failed but by using the hormonal techniques used in by me 1993 and 1994 I managed to get all of my four females to produce fertile eggs. One pair has bred naturally and the rest by AI. This was all done in less than a year to demonstrate to the police and the RSPB that I can and did breed peregrine falcons without any trouble as I did in 1992 to 1993 in spite of what the RSPB claimed.
