produce fertile eggs in captivity
In the period 1978-2003 306 clutches were laid with 1231 eggs of which
44,9% were fertile (n=553). Hatching success was 73,4% and 406 young
were fldged. Fertility rate (44,9%) is somewhat lower for the Swedish birds
compared to falcons in the earlier period of the North American breeding
programmes with 55,6% (The Peregrine Fund, USA) and 47,1% (Canadian
Wildlife Service) (Cade & Fyfe 1978). However, the latter breeding programmes
have used artifiial insemination(AI) to increase the fertility rate.
