"The breeding home ranges of eight colour-marked Shoveler (Anas clypeata) pairs which utilized irrigated grassland habitat near Strathmore, Alberta, each contained a "core area", a nest site, and several (3 to 13) "peripheral" ponds. Home ranges were between 20 and 128 acres in size, with a mean of 76 acres. Each core area was occupied 60 to 90 per cent of the time on the home range, and it appeared to supply basic requirements of food, loafing area and pair isolation"--Abstract, p. 5.
