The purpose of this study was to determine hummingbird preference between protein and higher sugar concentrations, and how any preference affects competition and memory. We hung three sets of three feeders in triangular patterns and observed hummingbird visits and interactions. We also, noted solitary feedings on the days directly following both site establishment and feeder rotation. Our results showed that there was an overall preference for the feeder with higher sugar concentration, that larger species and newcomers were generally dominant and that birds did not take longer to learn the values of established leaders that had been rotated than feeders whose contents were unknown. We concluded that larger, more aggressive birds had a stro...
