Population status

Gray Partridge
(Perdix perdix)

The Gray Partridge is well monitored by the Breeding Bird Survey (BBS), which provides good coverage of the Canadian breeding population. BBS results indicate that the population trend is slightly negative, but current abundance in Canada is relatively similar to that of the early 1970s. The annual indices reflect large fluctuations in the population over time (see Canada graph below), which are likely a result of predator cycles and adverse winter weather (Carroll 1993). BBS results from throughout North America suggest a loss of about 39% of the continental population. A national population goal has not been established for this introduced species.
