Description
Territorial hummingbirds often display aggressive behaviors to gain access to high-quality food sources. Previous studies have found that hummingbirds prefer to feed from feeders that have sugar concentrations that are slightly higher than regular flower nectar concentrations (20-25% sugar). However, to maximize their energy intake, hummingbirds may not always choose artificial feeders with the highest sugar concentration available to them. I used artificial feeders with varying sugar concentrations to determine if hummingbirds display more aggression and/or spend more time at feeders based on their sugar concentrations.
