Stage 1 — Discovery, Identification & Reunification

Woodchucks are the common lowland eastern North American marmot, but western and northern regions have other Marmota species. Photograph the animal and habitat, record the exact location and compare against the local species directory before using woodchuck-specific ages or release rules.

1. Use gloves. Do not hold a woodchuck against your body or let children handle it.
2. Keep the baby at the exact find location. Do not relocate it to another burrow or park.
3. For a known disturbance such as landscaping, construction or a dog digging at the den, place the baby in an open shoebox or low secure container near the original den area.
4. Place gentle supplemental warmth under only part of the setup; the heat source must not directly contact the animal.
5. Keep people and pets completely away. Watch from a building, vehicle or long distance.
6. Try during daylight and allow roughly 1–3 quiet hours when weather and safety permit.
7. If the mother does not return, the animal worsens, or no den disturbance explains why the baby is out, contain it and continue to Stage 2.

• Exact map pin and den/burrow location
• Species guess and clear photographs
• Date, time, temperature and weather
• Whether excavation, flooding, mowing, trapping or a dog disturbed the burrow
• Any bite, scratch, saliva or pet exposure involving people or domestic animals
• Initial weight in grams when safe to obtain
• Anything already fed, given or applied

Woodchuck-specific measurements are kept separate from broader marmot guidance because age, social structure, climate and release timing vary across Marmota species.
