Myth-Busting Monday: Your Budgie Doesn’t Need Grit
The myth: “Birds need grit to digest their seeds, so every budgie or cockatiel cage should have a grit cup.”
The truth: parrots, including budgies, cockatiels, lovebirds, and the big hookbills, don’t need grit. The Merck Veterinary Manual lists it among the myths of parrot nutrition that research has “debunked.”
Where the myth comes from
It started with a real fact about other birds. Pigeons and doves swallow seeds whole, hull and all. Birds have a two-part stomach, and the muscular second part (the gizzard) grinds food. Seed swallowers keep small stones there to do the grinding. Merck says grit is needed by pigeons, doves, and “some passerines” that eat seeds whole.
Parrots work differently. Watch a budgie at the seed dish and you’ll see it crack each seed with its beak and drop the empty husk. It swallows only the kernel, so its gizzard has no hulls to grind. Merck describes parrots in general this way. Even wild budgies, which live mostly on grass seed, hull their food first.
The habit hangs on, though. In a 2026 survey of 433 Italian parakeet keepers, grit was still “frequently provided”, especially by breeders. If you have a grit cup, you’re in good company.
Why “it can’t hurt” isn’t quite right
Most birds ignore grit or peck at a little. The concern is the bird that doesn’t stop. VCA Animal Hospitals notes that some birds eat too much grit when it’s offered and develop digestive blockages that can be serious. Their advice for cockatiels is not to offer grit or gravel at all. Since the benefit is zero and the risk isn’t, the cup isn’t worth keeping.
One honest caveat: avian vets do sometimes give grit on purpose. In a 2009 budgerigar study, grit helped tiny metal objects pass out of the gizzard faster. That’s a treatment your vet chooses for a specific problem, not a daily supplement.
Grit isn’t the same as calcium
Some products sold as “grit” are really calcium sources, like crushed oyster shell. Cuttlebone is a calcium source too. Those are separate questions from the grinding-stone myth. VCA notes that birds eating mostly pellets generally don’t need supplements, while egg-laying hens may need extra calcium. Ask your avian vet what fits your bird.

What to do
- Parrot of any size? You can retire the grit cup. Put the effort into the diet instead. Merck calls all-seed diets “suboptimal” for parrots, whatever you add to them.
- Finch, canary, pigeon, or dove? Their needs differ by species, so ask an avian vet rather than assuming either way.
- Bird has had grit and seems off? If it’s fluffed up, eating less, or its droppings have changed, call an avian vet. Don’t wait to see whether it passes.
Taking the grit cup away isn’t a correction of anything you did wrong. The advice changed, and now you know. For more on setting up a cage, see our cockatiel cage guide.
