Abstract

This project examined whether zebra finches habituate to road noise when presented with continuous playback of road traffic noise versus intermittent noise playback as they learned novel foraging tasks. Anthropogenic noise pollution levels are increasing in natural communities with numerous impacts on the behavior of animals, including recent studies demonstrating that noise negatively affects cognitive performance in birds. We used a battery of foraging tasks that measured different aspects of cognition, including inhibitory control, motor learning, color association, and spatial memory. Data available include cognitive performance data for birds undergoing different types of noise playback while learning to solve these tasks. Results indicate that birds presented with continuous noise exposure had higher performance scores in the motor learning and spatial memory tasks, but we did not observe differences between treatments for inhibitory control or color association tasks. Animal research was approved by the Pacific University Animal Care and Use Committee and conforms to the Animal Behavior Society Guidelines for the treatment of animals in behavioural research and teaching.
