Introduction
Although the birds of prey are among the largest landbirds, studying raptors is not easy. We still lack basic data on population size and trends for most species. While studies have taken place across Canada, there is no nationally coordinated program to monitor raptor populations, largely because this group of birds falls under provincial jurisdiction in Canada. Efforts to improve raptor monitoring are underway, but until there are enough data from these renewed efforts, much of our information on raptors is generated by work on species at risk. This issue of Bird Trends summarizes some recent studies of this group of birds, but many questions about the status of raptors in Canada remain, for now, unanswered.
