In the following calculations of fertility rate, hatching success and
life-time reproduction we have used data from 75 falcons (38 females and
37 males) from the period 1974 -2003. Of the 38 females 76% (n=29) produced
eggs but only 20 (53%) laid fertile eggs and produced young. Of the males it
was 17 (46%) that copulated with females and contributed to fertile eggs and
16(43%) were involved in production of young (Tab. 2).
