. Patterns of Barnacle Goose colony growth in the central part of Kolguev. Colony names correspond to those shown on Fig. 1. Falcon-
associated colonies are listed as “F”, bog colonies – as “B”. Cases when Peregrine falcons were nesting are shown in bold. Colony size is given in
number of nests. Blank cells correspond to data absence. Zero values correspond to definite absence of Barnacle Geese nests at the site in a given
season. Falcon territories where no colonies were recorded during the study were not allocated a colony code.
