When risks are present, animals consider the costs and benefits of foraging. This study investigates the preferred feeder positions when potential risks are involved in feeding hummingbirds. Two experiments were conducted in this study in order to have a better understanding of animal risk assessment. The first experiment examined whether there was a preference for high or low feeders in hummingbirds. Results showed that hummingbirds had a preference for higher feeders. Results also showed that hummingbirds have a greater preference to feed from feeders that are closer to trees (outer) than feeders farther away (inner) from trees. The second experiment showed no significant difference in the number of visits of hummingbirds when artificial ...
