Identification via Excrement!!!!

Optional Terminology
• Feces• Excrement• Pellets• Droppings• Poop• The list could
go on and on….

An Important Mammalian ID Tool
• Mammals versus Birds….• Mammals separate waste into solid
and liquid• Birds and some reptiles void 1
substance

Full of Useful Information…• It can be smelly, gross, disease ridden…BUT!• Is filled with great ID information:1. Diet:
– Hairs, feathers, bones, insect limbs and shells, fruit skins, seeds
2. Population size/location of the species
3. DNA Information4. Health of the animal: parasites

LimitationsTremendous variety due to:
•Seasonal food availability•Age and health of animal•Other stresses on the animal

General Characteristics
• Twists:• Weasels-extremely twisted and
narrow
• Canine family-sometimes twisted
![Page 11: Mammalian Scats Identification via Excrement!!!!](https://reader035.vdocuments.mx/reader035/viewer/2022062517/56649f175503460f94c2d572/html5/thumbnails/11.jpg)
Animals without Twists…
• Cats (feline)
• Bears
• Raccoons

Segmented???
• Cats usually have segmented scats
• Canine and Weasels tend to be 1 cord

Blunt versus Tapered????
• Canines tend to have 1 or more tapered ends
• Weasels—long and thin tapered ends• Blunt ends—cats, raccoons, bears

Given those Characteristics…..GREAT VARIABILITY
