Can Birds Eat Oatmeal? Raw Oats Yes, Cooked No

The short answer

• Dry, plain rolled oats are safe for birds. The RSPB lists dry porridge among kitchen scraps that suit garden birds and cooked porridge oats among foods to avoid.
• Old-fashioned and quick oats are the same food: USDA gives them one entry, at 379 kcal, 6.52 g fat and 13.15 g protein per 100 g. Flavored instant packets are a no, at 30.28 g sugar and 505 mg sodium per 100 g.
• Per pound, oats carry about 29.6 g of fat. Black oil sunflower carries about 173 g and white proso millet about 15 g. Oats are a grain, not a winter fat food.
• Few North American feeder birds want oats. In the 1980 Fish and Wildlife Service feeder study, hulled oats drew 0.002 times the visits of white proso millet. Starlings liked them; mourning doves and house sparrows took them.
• Put out a small handful on a tray or the ground, only what is gone by dusk, and never in rain. Wet oats turn to paste and mold.

Yes, birds can eat oatmeal if it is dry, plain and uncooked, but cooked oatmeal is a no. The RSPB, the UK bird charity, lists dry porridge among the kitchen scraps that suit garden birds, and it lists cooked porridge oats among the foods to avoid. Flavored instant packets are a no as well, because of their sugar and salt.

Safe is not the same as useful, though. Few North American feeder birds want oats, and a pound of them carries little fat.

What "oatmeal" means here#

In the US, oatmeal names two different things. One is the dry flakes in the canister, and the other is the hot cereal you cook from them, which the British call porridge. That double meaning is why the question seems to have two answers that clash.

The Whole Grains Council sets out how the dry kinds are made:

• Groats are whole oat kernels with the hard outer husk (the hull) taken off.
• Steel-cut oats are groats cut into two or three pieces with a blade.
• Rolled oats, also sold as old-fashioned oats, are groats that are steamed and then rolled into flakes.
• Quick oats and instant oats are flakes rolled thinner or steamed longer.

All of these are the same kernel. Whether a bird should eat it turns on two things: whether it was cooked in water, and what was added to it.

Which kinds of oats are safe#

Cooked oatmeal. The RSPB lists "cooked porridge oats" as a food to avoid, alongside dried coconut, milk and salted food. The Woodland Trust says the same thing: no cooked porridge, though porridge oats are fine. Many sites add a reason, which is that cooked oats turn sticky and can harden around a bird's beak. That line is widely credited to the RSPB, but we did not find it on the two RSPB pages we read, and neither page gives any reason at all. No study we found has measured it either, so treat the beak warning as cautious guidance rather than a tested result.

There is a plainer problem with cooked oats. USDA puts cooked oatmeal at 83.61 g of water per 100 g, so a pound of dry oats turns into about 5 lb of porridge. That much water sitting on an open tray spoils fast.

Instant packets. USDA's maple and brown sugar packet holds 30.28 g of sugar and 505 mg of sodium per 100 g. Plain rolled oats hold 0.99 g of sugar and 6 mg of sodium. That gives the packet about 30 times the sugar and 84 times the salt. Even plain instant oats carry 220 mg of sodium per 100 g. Salt is a dose problem for a bird that weighs about an ounce, as what not to feed birds explains.

Quick against old-fashioned. USDA gives them one entry, so as food they are the same. The thinner flake soaks up water faster, which is why quick oats cook faster, and on a tray it goes soft sooner in damp air. If you have both, put out the old-fashioned kind.

Oats against sunflower and millet, per pound#

This is the comparison the other pages on this question leave out. The oat row comes from USDA FoodData Central. The two seed rows use this site's own bird food nutrition figures, worked out per pound as you buy it, with the hull counted as weight that feeds nothing.

The seed rows multiply the site's kernel figures by its kernel yields, which are 75% for black oil and 82% for millet. The oat row is USDA's 379 kcal, 6.52 g fat and 13.15 g protein per 100 g, times 4.536.

Three things come out of that table.

Oats are not a winter fat food. Pound for pound, black oil sunflower has about six times the fat of oats. On a cold night fat is what a small bird burns, which is why winter bird feeding leans on sunflower and suet.

Oats beat millet on paper. Kernel for kernel, oats and millet carry about the same energy, at 379 kcal and 378 kcal per 100 g. Oats come with no hull, so a pound bought gives more food, and they have about twice the fat and half again the protein.

Paper is not the feeder. A food only counts if birds eat it, and that is where oats fall down.

Which feeder birds actually eat oats#

The best North American evidence is a feeder study by A. D. Geis, published by the U.S. Fish and Wildlife Service in 1980. It ran feeding tables in Maryland and counted both the visits to each food and how much of it was eaten. It tested hulled oats (groats), not rolled flakes. Here is what it found:

• Starlings "showed a striking preference for peanut hearts and hulled oats."
• Mourning doves found hulled oats attractive, among several other foods.
• House sparrows "ate almost everything except flax and rape seed."
• Whole oats, still in the husk, were "attractive only to starlings."

Pooled across every bird, hulled oats drew 0.002 times the visits of white proso millet, which is about one visit to oats for every 500 to millet. By weight, birds ate about 3% as much oats as millet. Geis called adding hulled oats to mixes "ill-advised."

So expect the ground crowd. Mourning doves, house sparrows and starlings are the likely takers. A tray of grain can pull in a whole flock of starlings, and starlings at feeders covers what to do then. Don't expect chickadees or finches. No source we found ranks rolled flakes by species, so this page does not claim juncos or native sparrows. The UK advice sounds more upbeat because it is written for British garden birds, which are a different cast.

This is also why oats appear on this site as filler. In a hanging feeder, birds rake them out to reach the sunflower, and the full case is in birdseed mixes.

A cold morning, worked through#

Take a hard frost and a canister of old-fashioned oats, and suppose you scoop half a cup onto a tray. USDA weighs a cup at 81 g, so half a cup is about 40 g.

1. Energy. At 379 kcal per 100 g, 40 g of oats is about 154 kcal.
2. Fat. At 6.52 g per 100 g, that same 40 g holds about 2.6 g of fat.
3. The same weight of black oil sunflower holds about 15 g of fat: 40 g, times 75% kernel, times 51% fat.
4. Now cook those oats. At 71 kcal per 100 g of porridge, the same 154 kcal comes as about 215 g of wet cereal. About 175 g of that is water, and it is the form the RSPB says to avoid.

So the half cup of dry oats is a fine extra for the doves, but it is not a swap for the sunflower feeder.

How to put oats out without mold#

Damp grain grows mold, and of everything on our do-not-feed list, mold is the most likely to kill a bird. The details are in moldy seed.

• Use a tray or the ground. A platform or tray feeder with a mesh floor drains best, and a ground feeder suits doves.
• Start with a small handful. Add more only if it is gone by dusk, and bring in whatever is left so nothing sits out in the dew.
• Skip wet days. Flakes soak up water, and oats that clump or smell sour go in the trash.
• Mix with millet if you like. In the 1980 study, doves and house sparrows took both.
• Store them dry. Keep the canister sealed and cool, as in storing birdseed.

A pile of grain left out overnight also feeds mice. If that is a worry where you live, see rats and mice.

What this answer does not cover#

The RSPB and Woodland Trust pages are British advice written for British birds. The feeder study comes from Maryland more than 40 years ago, and it tested hulled oats rather than rolled flakes. Its numbers pool every bird that visited, so a single species may behave differently. No source we found measured how much rolled oat any wild bird eats. The nutrition figures are USDA values for oats sold as human food, and bulk oats or groats sold as birdseed may differ. Nothing here applies to pet birds, whose diets are a matter for an avian vet. For the wider list of kitchen scraps to keep off the tray, start with what not to feed birds. For a cheap ground food that birds actually want, white proso millet is the seed the same study called the best for small seed-eating birds.

Frequently asked questions#

Can birds eat uncooked oatmeal?

Yes, if it is plain. Dry rolled oats, old-fashioned or quick, are on the RSPB's list of kitchen scraps that suit garden birds, where it calls them dry porridge. Put a small handful on a tray or on the ground, and only as much as the birds clear before dusk. Plain means the ingredient list says oats and nothing else.

Why can't birds eat cooked oatmeal?

The RSPB lists cooked porridge oats among the foods to avoid, and the Woodland Trust says not to put out cooked porridge. Neither page gives a reason. The reason you will see on many sites is that cooked oats turn sticky and set hard around a bird's beak. That wording is widely credited to the RSPB, but we did not find it on the RSPB pages we read, and no study we found has measured it. It is advice, not a test result. Cooked oats are also about 84% water, so they spoil fast on a tray.

Can birds eat quick oats?

Yes. Quick oats are rolled oats pressed thinner or steamed longer, according to the Whole Grains Council, and USDA gives regular and quick oats one nutrition entry. The thinner flake soaks up water faster, which is why it cooks faster, so it also goes soft sooner on a damp tray. Old-fashioned flakes hold together better on a tray, so pick those if you have the choice.

Can I give birds instant oatmeal packets?

No. A maple and brown sugar packet is 30.28 g sugar and 505 mg sodium per 100 g in USDA's data. Plain rolled oats are 0.99 g sugar and 6 mg sodium. Even plain instant oats carry 220 mg sodium per 100 g. Salt is a dose problem for a bird that weighs an ounce, which is why it is on our list of what not to feed birds.

Which birds eat oats?

In North America, not many. The largest feeder study we found, run by the U.S. Fish and Wildlife Service in Maryland and published in 1980, tested hulled oats. Starlings showed a striking preference for them. Mourning doves found them attractive, and house sparrows ate almost everything on offer. Across all birds, oats drew 0.002 times the visits of white proso millet. No source we found ranks rolled oats by species, so this page does not.

Can I put oats in homemade suet?

Yes. Rolled oats are a common dry ingredient in suet cakes, where fat binds them and keeps water out. That is a different case from a pile of loose oats on a tray. Proportions are in homemade suet recipes.
