Short Description of your Research or Creative Project (700 characters or less)

Urban environments provide wildlife with food from human waste, which generalist species exploit, increasing interspecific competition. American crows (Corvus brachyrhynchos), common ravens (Corvus corax), and gulls (Larus spp.) frequent these sources, yet their competitive outcomes remain understudied. This study explores food competition between these species in Arcata and Eureka, California. I hypothesize that crow competitive success increases with group size. Understanding how social behavior impacts these outcomes will contribute to a deeper knowledge of urban ecology.
