Online resources: Summary: Breeding and non-breeding ducks commonly respond to terrestrial predators or novel moving objects by approaching or following sucn stimuli (Hochbaum 1955) This behaviour, called tolling (Hochbaum 1955) has been exploited to capture ducks for consumption or reserarch (McCabe & Mulder 1961. Kear 1990, Owen & Block 1990, Karelse 1994) The adaptive significance of tolling in waterfowl is unknowl1 but may be a curiosity (Hochbaum 1955) or mobbing response (Kear 1990, Owen & Blacll 1990) To our knowledge, there are no publisfled reports of tolling by geese on Arctic breeding grounds (but see Abraham 1980), We report observations of tolling in Ross's Chen rossii and Lesser Snow geese Chen caerulescens caerulesce11s I/iereafter Snow Geese) and consider the potential adaptive basis for this behaviour.
