The pilfering of puffins: behavioural tactics of herring gulls and Atlantic puffins during kleptoparasitic competition
Kleptoparasitism is a foraging strategy whereby an individual steals a procured food item from another individual. Individuals can optimize their kleptoparasitic foraging strategy by modifying their behaviour to expend less energy than they would by foraging independently or by attacking more profit...
