Abstract. The degree of synchrony between populations is critical for their dynamics at large spatial scales. Population synchrony has been assessed for only a few species of vertebrates, most of them have largely fluctuating populations with multiannual cycles. We investigated the intensity and spatial extent of synchrony among populations of birds in Britain. The data analyzed ran from 1962 to 1995 at more than 1000 local sites and concerned 60 species. For each species, we measured the intensity of synchrony among local populations using the cross-correlation ...
