Falcons are good at chasing fast flocks of small dunlin, hawks put the run on ducks and crows, and eagles tackle the larger birds, including geese and herons.???They???ll occasionally take the odd duck, but we don???t actively try to catch birds,??? says company owner Gillian Radcliffe.Some 100 red-tailed hawks have been relocated from Sea Island over the years to areas such as Chilliwack.
