Abstract
Plastic pollution is a significant conservation issue and represents a significant threat to wildlife in marine and aquatic systems. Less understood is plastic pollution in terrestrial systems, especially those that are remote and/or protected. Here, we document the surprising discovery of the plastic bristles of a hairbrush embedded in the haypile of an American Pika (Ochotona princeps) in a remote area of Glacier National Park, Montana. We hypothesize that the bristles of the hairbrush, given their appearance, may have been perceived by the pika as herbaceous plant material that could potentially serve as a food resource during winter, when pikas rely on their haypiles as a food cache. We discuss the possible origins of the plastic materials and conservation implications for pikas and other animals living in remote protected areas.
