This scat may be up to five times longer than it is wide and it may contain undigested insect parts. You can find it in western North America, near lakes or ponds. It is getting less common, however; ICUN Red List reports this species is probably in significant decline due to diseases such as chytridiomycosis.

This scat can vary widely in color but is most often black. You might find scat from more than one individual in a pile. But you would not want to touch or even smell this scat, particularly because it may contain a deadly parasite.

This scat changes depending on the time of year. It consists of many pellets, which may scatter or, when moist, may stick together. It can be found in forested areas on the Pacific Coast.
