Abstract

Hummingbirds act as important pollinator species. Without artificial feeders, hummingbirds would be forced to move around to different flowers locations to find nectar and thus be less predictable to a predator. In an urban environment, hummingbirds feed off of flowers as well as feeders placed and maintained by people. As feeders provide abundant food, hummingbirds often habitually return to the same feeder. This provides a unique opportunity to predators. If hummingbirds are not able to properly identify or respond to threats near a feeder, they are likely more susceptible to predation. This may significantly affect hummingbird demographics in urban areas and/or apply selective pressure towards behaviors that minimize predation. In this study, various predators and threats will be presented at established feeder sites by using both artificial predator decoys and vocalizations. These responses will be video recorded, analyzed and interpreted. This investigation will result in better understanding of the broader impacts of artificial hummingbird feeders within the urban environment.
