The Curious Case of Red Milk in the Animal Kingdom
When we think of milk, the typical images that come to mind are those of white or creamy liquids, primarily from cows, goats, and other common dairy animals. However, there are rare instances in the animal kingdom where milk takes on a strikingly different hue—specifically, a reddish tint. This phenomenon is most notably observed in certain species of birds and mammals.
Pigeons: The Unlikely Producers of Red Milk
One of the most fascinating examples of red milk production comes from pigeons. These birds produce a substance known as “pigeon milk,” which is not milk in the traditional sense but rather a nutrient-rich secretion from the lining of their crop. This secretion is a bright yellowish-red color and is used to feed their young during the first few days of life. The color comes from carotenoids in their diet, which are pigments found in various plants and seeds. This unique adaptation allows pigeon parents to provide their chicks with essential nutrients and antibodies, ensuring their survival in the critical early stages of development.
Other Notable Mentions
While pigeons are the most recognized producers of red milk, there are other animals that can produce milk with unusual colors, though they may not be classified strictly as “red.” For instance, the greater flamingo also produces a reddish secretion to feed its young, which is similar in function to pigeon milk. This secretion is rich in carotenoids, contributing to the pink coloration of the flamingos themselves as they consume these pigments from their diet.
The Science Behind Colorful Milk
The coloration of milk in these species is primarily due to the presence of carotenoids, which are organic pigments found in many plants. These pigments not only provide color but also serve as antioxidants and play a role in the health of the young birds. The ability to produce such colorful milk is an evolutionary adaptation that enhances the nutritional value of the food provided to offspring, ensuring they receive the necessary components for growth and development.
Conclusion
In summary, while red milk is not a common occurrence in the animal kingdom, it is a remarkable feature of certain species like pigeons and flamingos. These birds have evolved unique methods of nourishing their young, showcasing the incredible diversity and adaptability of life on Earth. The vibrant colors of their milk serve not only as a nutritional boon but also as a testament to the intricate relationships between diet, environment, and survival in the animal world.

Hippos milk is bright pink. The reason is that the hippo secretes two kinds of unique acids called “Hipposudoric acid” and “Norhipposudoric acid”. The former is reddish in color and often known as “blood sweat”, although it is neither blood nor sweat. The latter is is bright orange.
Can cows make pink milk?
Today, cow #612 produced “strawberry milk.” Pink-tinged milk or “strawberry milk” occurs when red blood cells (RBCs) gain access into the lactation system.

What color is a rhino’s milk?

Which animal has green milk?
Thala-siren. Ahch-To’s thala-sirens are docile marine mammals that like to sun themselves on rocks fringing the coasts of the planet’s islands. Sea sows produce a nutritious green milk, which is harvested by the native Lanai and adventurous visitors.
Why is a Hippo’s milk pink?
Although this thick secretion comes out colorless like human sweat, it gradually turns red, pink or orange as the pigment polymerizes in the sun. After a few hours, it turns brown. This secretion could possibly then mix with the milk when a baby hippo is feeding, which could give the milk a pink hue, Lewison said.
Is there any black milk?
The female black rhinoceros or Diceros bicornis give black milk. Black milk is the slimmest milk containing very little amount of fat (0.2%) is produced by Black rhinoceros.
