Can Birds Drink Milk?

Milk and birdseed seem to go hand-in-hand as classic staples people associate with feeding and caring for birds. But is milk actually a healthy drink choice for our feathered friends? Or is the dairy beverage better left for human consumption? Let’s analyze the nutrition, risks, benefits, and best practices for offering milk to birds.

Nutritional Value of Milk for Birds

Milk contains the following key nutrients:

  • Protein – Milk proteins provide amino acids for building muscle and tissues.
  • Fat – A source of concentrated calories and energy.
  • Calcium – Critical for bone health and egg shell strength.
  • Vitamin D – Needed for calcium absorption and immunity.
  • Vitamin A – Supports vision, skin, feathers, and mucous membranes.

So milk does offer a nutritional package that could theoretically benefit birds in some ways. But risks still exist.

Potential Benefits of Milk for Birds

Possible benefits of milk for bird health include:

  • Stronger bones – The calcium and vitamin D in milk promotes bone density and prevents fractures and deformities.
  • Improved feather quality – Keratin proteins in milk may contribute to fuller, healthier plumage.
  • Aiding egg development – Calcium and vitamin D are especially important for breeding hens producing eggs.
  • Supporting growth – Milk protein provides amino acids for muscle development in nestlings.
  • Healthier skin and eyes – Vitamin A in milk helps with vision and keeps skin and mucous membranes in good condition.

Potential Risks of Feeding Milk to Birds

However, there are also some notable risks with offering milk:

  • Digestive upset – Most adult birds lack the lactase enzyme to properly digest the lactose in milk. Can cause cramps and diarrhea.
  • Allergies – Dairy allergies and intolerances are possible. May cause skin reactions, sinus congestion, or anaphylaxis.
  • Bacterial contamination – Milk spoils easily and can harbor harmful pathogens like salmonella and E. coli.
  • Obesity – The high fat content of milk conflicts with the low-fat diet most birds naturally require. Excess calories.
  • Reduced appetite – Milk may fill birds up without providing complete nutrition, reducing their appetite for more suitable foods.

Overall, the risks seem to outweigh potential benefits for most birds.

Best Practices for Offering Milk

If trying milk for certain bird species, follow these guidelines:

  • Give only as an occasional treat, not a daily drink.
  • Choose plain full-fat milk, not low-fat or flavored milks.
  • Ensure milk is well chilled prior to serving.
  • Pour into a shallow dish, not a deep vessel birds may drown in.
  • Remove any uneaten milk within 1-2 hours to prevent spoiling.
  • Monitor closely for signs of digestive upset or allergic reaction.
  • For young nestlings, provide milk-soaked bread in tiny portions.

Even when following precautions, many birds still should not have milk at all.

Suitable Bird Species for Milk

Only certain birds may potentially benefit from a small amount of milk. These include:

  • Young nestlings – Requires natural enzymes to digest.
  • Pigeons – Naturally drink a milk-like substance called crop milk to feed young.
  • Sparrows – Have shown ability to process lactose.
  • Crows – Can scavenge dairy without issue.

All other birds are best avoided giving milk. Their digestive systems just can’t handle it.

Healthy Alternatives to Milk for Birds

Instead of milk, provide birds with:

  • Fresh clean water – The ideal bird beverage for hydration!
  • Calcium-fortified bird pellets or powder – Better absorbed source of calcium and D3.
  • Chopped hard boiled eggs – Provide protein and biotin for feather health.
  • Multivitamin spray for birds – Boosts overall nutrition.
  • Greens like kale, spinach and broccoli – Calcium without dairy.

A varied diet will supply all the nutrition birds need without milk.

Can Powdered Milk be Used?

Powdered milk is sometimes used for baby birds. However, it has more potential downsides:

  • Higher bacterial contamination risk from preparation.
  • Over-concentration of nutrients when mixing.
  • Oxidation from heat and processing that damages vitamins.
  • Caking that obstructs crop and digestion.

The nutrients may not properly absorb. Stick to natural whole food sources as much as possible.


While milk may seem appealing for its protein and calcium content, it poses substantial digestive and health risks for most species of adult birds. The best approach is avoiding milk altogether and instead focusing their diet on quality seeds, produce, sprouted grains, and bird pellets to meet nutritional needs. For temporary supplementation of orphaned babies, small amounts of milk-soaked bread may provide some sustenance but is still not an ideal long-term diet replacement. Understanding the limitations birds face in processing dairy can help ensure we offer them a safe, healthy diet.


Can baby birds drink milk from a bowl?

Newly hatched nestlings should only have parental crop milk. Once weaned, shallow dishes of milk can provide trial nutrition but easily spoil.

Do bird parents ever feed milk to babies?

Pigeon parents produce a nutritious crop milk substance high in fat and protein. Other adult birds do not naturally feed actual milk to offspring.

Is it okay to give milk in very small amounts?

Tiny portions may reduce risk of digestive upset but lactose and allergy challenges would still remain. Best to avoid entirely.

Can finches and canaries drink milk?

Finches and canaries lack the enzymes to digest lactose and are very prone to cramping and diarrhea from milk. Do not offer them any.

Why do some birds bathe in milk?

Birds may bathe in milk for hydration, to soften feathers, or out of curiosity. But the risks of spoilage and infection outweigh any benefits.

Is condensed milk safer for birds than regular milk?

No, the added sugar in condensed and sweetened condensed milk makes it even more problematic for bird digestion and pancreas function.

Can bird parents produce milk for babies?

No bird species except pigeons actually produce true milk. Parent birds regurgitate food they swallow to feed young.

Is powdered milk a better choice than liquid?

No, powdered milk also contains lactose, may concentrate nutrients excessively, and lacks the fresh enzymes of liquid milk.

What milk alternatives can I offer birds?

Some safe calcium-rich options are dark leafy greens, calcium blocks, cuttlebone, bone meal powder, boiled egg shells, or mineral supplements.
