Since 1972, 807 Peregrine Falcon chicks have been banded in Victoria and 66 of these have been either recovered
or resighted. There was a slight but significant (P < 0.05) female-bias in the sex ratios of both the nestlings banded
and the subsequent band recoveries. Most (69.7%) recoveries were made more than 4 km from banding (nest) sites.
Of the 66 recoveries, 60 were of either dead or injured birds, with the main determinable cause being flying accidents,
particularly collisions with vehicles and overhead or fence wires. Females dispersed further, may have settled and
bred further from their natal sites, and lived longer than did males. A large portion of the recoveries of banded birds
were made within one year of their leaving the nests. Most recoveries of banded birds less than one year old were
made within the first six months (December-May) of their leaving the nests, whereas recoveries of those birds which
survived the first year were most often made during the four main breeding months of August-November.
