Field notes from an autumn walk where dropped peanut shells under a feeder had drawn the local geese in for a forage.
Updated: 2026-05-20.
The short version: yes, geese can eat most nuts in small amounts, but the rules are strict. Raw, unsalted, and chopped fine - that’s the safe form. Peanuts (botanically a legume), almonds, walnuts, pecans, hazelnuts and cashews are fine in moderation. Salted varieties are harmful because of sodium toxicity. Bitter almonds contain amygdalin (cyanogenic) and should be avoided entirely. Macadamias have undocumented toxicity for birds and are best skipped. A small handful per goose per week is the right portion.
The general rule for nuts and geese
Nuts are calorie-dense and protein-rich - useful as occasional supplements but never as a staple. The Merck Veterinary Manual’s waterfowl nutrition guidance highlights moderation and avoidance of high-fat additions to herbivore-leaning diets.
The general rules:
- Raw only. Roasted is acceptable if completely plain; salted/smoked/flavoured is not.
- Chopped fine. Whole nuts are choking hazards.
- Tiny portions. A goose’s daily nut allowance is a teaspoon at most.
- Variety. Rotate nut types rather than feeding the same one daily.
Per-nut breakdown
Peanuts (Arachis hypogaea)
Technically a legume, not a nut, but treated as one nutritionally.
- Safe? Yes, raw and unsalted.
- Form: chopped peanut pieces. Whole shelled peanuts are too large for geese to manage cleanly.
- Avoid: salted, dry-roasted, honey-roasted, smoked. The salt is the main risk; see can ducks eat peanut butter for the equivalent peanut-butter case.
Almonds (Prunus dulcis)
The sweet almond is the supermarket variety - safe.
- Safe? Yes, raw, chopped, sweet variety only.
- Form: chopped to 4-5mm pieces.
- Critical avoidance: bitter almonds (Prunus dulcis var. amara) contain amygdalin, a cyanogenic glycoside. In the EU and US, bitter almonds aren’t sold for consumption - but if you encounter them via almond extract or specialty grocers, don’t feed them. The compound metabolises to hydrogen cyanide in the gut.
For the parallel duck case, can ducks eat almonds.
Walnuts (Juglans regia)
- Safe? Yes, raw, chopped, in tiny amounts.
- Form: chopped, no shells.
- Note: very high in fat (65%). Even smaller portions than other nuts.
Pecans (Carya illinoinensis)
- Safe? Yes, raw, chopped.
- Form: chopped, no shells.
- Note: also high in fat, treat as walnuts.
Hazelnuts / Filberts (Corylus avellana)
- Safe? Yes, raw, chopped.
- Form: chopped pieces.
Cashews (Anacardium occidentale)
- Safe? Yes, raw or unsalted dry-roasted, chopped.
- Form: chopped pieces.
- Note: commercially-sold cashews are always already heat-treated to remove urushiol-related compounds in the raw kernel.
Brazil nuts (Bertholletia excelsa)
- Safe? Trace amounts only.
- Note: extremely high in selenium - a single brazil nut contains 5-10x the recommended daily selenium for a small bird. Skip these for safety.
Macadamias (Macadamia integrifolia)
- Safe? Best avoided.
- Note: documented toxicity to dogs (vomiting, weakness, ataxia). Mechanism not fully understood. Insufficient research in waterfowl, so the safe assumption is to avoid.
Pistachios (Pistacia vera)
- Safe? Only unsalted shelled. The salt in retail pistachios makes them unsuitable.
- Form: shelled and chopped.
The salt issue (the master rule)
Salt is the deciding factor in most “should I feed this nut” questions. The Open Sanctuary Project’s goose feeding guide emphasises low-sodium diets - and most retail nuts are heavily salted.
Sodium toxicity in waterfowl progression:
- Mild excess: increased thirst.
- Moderate: loose droppings, weakness.
- Severe: neurological signs, seizures, kidney failure.
A handful of salted peanuts (10g of nuts, ~150mg sodium) is enough to be a problem in a goose. Stick to plain raw.
For the broader case on salted treats, see can ducks eat pickles and can geese eat cat food.
How much, how often
The nut-treat guideline:
- Per goose per day: about a teaspoon of chopped nuts.
- Per week: 1-2 times.
- As percentage of diet: under 5% by weight.
A handful of chopped peanuts (30-40g) shared between 3-4 geese is a reasonable treat meal.
Wild geese vs. backyard flock
If you’re at a park pond, skip nuts entirely. They sit on the bank, attract rats and rodents, and aren’t a natural pondside food. Bring cracked corn or oats instead. See best food to feed ducks and geese and what can I feed ducks at the pond.
For backyard flocks, nuts are a small enrichment alongside the everyday calorie base.
The everyday treats geese should actually have
In order of usefulness:
- Pasture grass - the natural food.
- Formulated waterfowl pellets - the staple supplement.
- Cracked corn - calorie supplement.
- Chopped fresh greens - kale, lettuce, peas.
- Occasional fresh fruit - apple, berries, melon. See can geese eat mango, can geese eat kiwi, can geese eat blackberries.
- Tiny amounts of chopped raw unsalted nuts - occasional enrichment.

The bottom line
Yes to nuts for geese - raw, unsalted, chopped, in tiny amounts. Peanuts, almonds, walnuts, pecans, hazelnuts all safe in moderation. Bitter almonds and macadamias should be avoided. Salted versions of anything are a no. Treat nuts as rare enrichment alongside the everyday pasture and cracked-corn base.
