What Do Chipmunks Drink? Mostly Water They Never Find
Chipmunks get most of their moisture from food — fruit, fungi, insects and green shoots — and drink free water only when it is easy to reach.

Water — when it is easy to reach. But most of a chipmunk’s moisture comes from what it eats: fruit, fungi, insects, earthworms and green shoots are largely water. A well-fed chipmunk needs very little on top.
Where the water actually comes from
| Source | Share of intake |
|---|---|
| Moist food — berries, fruit, fungi, insects, worms | Most of it |
| Dew on leaves and grass | Significant, early morning |
| Puddles, pond margins, damp ground | Opportunistic |
| Bird baths, dripping taps | Opportunistic |
| Metabolic water from burning fat and carbohydrate | Small but real, and matters in winter |
Winter
Chipmunks do not truly hibernate. They enter bouts of torpor in the burrow and wake periodically to eat from a cached store.
- Metabolic rate drops enormously, and water demand drops with it
- Burrow air is humid, so losses through breathing are low
- Cached seeds and nuts plus metabolic water cover the rest
That is why you do not see chipmunks hunting for water in January.
If you want to put water out
Make it shallow, or put stones in it
Small mammals drown in steep-sided water containers far more often than people expect. A shallow dish, or a deeper one with stones piled so an animal can climb out, removes the risk entirely.
Do it because you want to watch them, not because they need it. They range widely enough to find dew, puddles and damp ground on their own.
What not to give them
Nothing but plain fresh water. Like most adult mammals chipmunks are lactose intolerant, so milk causes digestive upset. No juice, no sugar water, no milk.
If you want fewer chipmunks, remove seed, not water
Moisture is replaceable from a dozen natural sources. A reliable pile of spilled sunflower seed under a feeder is not. Food is the draw; water barely registers.
An honest note on “how long without water”
You will find confident numbers online. There is no reliable published figure for chipmunks, and anyone quoting a specific number of days is guessing. What is true: small mammals with high metabolic rates dehydrate quickly, and a trapped chipmunk with no food or water is in trouble within a day.
