Abstract

This study, conducted near Cambridge, Ontario, associated selected characteristics of ponds with pond use by Mallard Anas platyrhynchos from April through September 1977-78. Use by Mallard pairs was positively related to pond size; however, the spacing of pairs on ponds suggested that pond use was probably regulated by behavioural mechanisms. Mallard broods frequented ponds with some surface cover; abundance of food appeared less important. Post-breeding Mallard used ponds supporting an abundant and accessible variety of plant foods. Autumn pre-migratory Mallard used ponds with numerous loafing sites and close to grain fields.
