Description

This project is a behavioral study on 4 gull species of Humboldt County. Their agonistic behavior was studied, comparing the frequency of agonistic behavior toward members of other species based on relative body-size. This value was compared with the number of birds of each relative size they had access to. I found that most gulls tended to target members of their own species disproportionately, but Western gulls disproportionately targeted members of other species that were larger and smaller in size. This may have implications on gull behavior and management.
