What Bird Lays Pink Eggs? A Look At Nature’S Rosy Ovals
While white and brown eggs may be the norm, some bird species lay eggs in shades of pink, rose, and even red. But what birds naturally produce these colorful oval gems? In this article, we’ll crack into the science of pink eggs and highlight the unique birds that lay them.
If you’re short on time, here’s the quick answer: The main birds that lay pink eggs include various finches, terns, owls, flamingos, and ducks.
What Causes Pink Eggs?
Have you ever wondered what causes some birds to lay pink eggs? The color of bird eggs is determined by a variety of factors, including genetics and environmental conditions. In the case of pink eggs, there are two main reasons why some birds produce these rosy ovals: pigments and camouflage.
Pigments
One of the primary reasons for the pink coloration of bird eggs is the presence of pigments. Pigments are chemical compounds that absorb certain wavelengths of light and reflect others, giving objects their color. In the case of pink eggs, the pigments responsible for this hue are called porphyrins.
These pigments are commonly found in the shells of birds like flamingos and certain species of gulls.
Flamingos, for example, lay pink eggs due to the high concentration of porphyrins in their shells. These pigments are obtained from the flamingo’s diet, which consists mainly of small crustaceans that contain these pink compounds.
As the female flamingo digests the crustaceans, the porphyrins are absorbed into her bloodstream and deposited in the developing eggs, resulting in their distinctive pink coloration.
Camouflage
Another reason why some birds lay pink eggs is for camouflage purposes. Camouflage is a crucial survival strategy in the animal kingdom, allowing individuals to blend into their surroundings and avoid detection by predators.
In certain environments where pink hues are prevalent, such as marshes or sandy areas, birds that lay pink eggs have an advantage.
By laying pink eggs, these birds are able to create a visual illusion that helps them blend in with their surroundings. This camouflage makes it more difficult for predators to spot the eggs, increasing the chances of survival for both the eggs and the offspring.
This adaptation can be observed in various bird species, such as the killdeer, a ground-nesting bird that lays pinkish-brown eggs with dark blotches, providing excellent camouflage in their natural habitats.
Finches with Pink Eggs
When it comes to colorful eggs, finches are a fascinating group of birds to explore. While most bird species lay eggs in various shades of white, brown, or speckled patterns, there are a few exceptions that stand out with their pink ovals.
Let’s take a closer look at two finch species known for their unique and eye-catching eggs.
Gouldian Finch
The Gouldian Finch, also known as the Rainbow Finch, is a small and brightly colored bird native to northern Australia. What sets this finch apart is not only its vibrant plumage but also its ability to lay pink eggs.
The female Gouldian Finch typically lays four to eight eggs in a clutch, and these eggs have a distinctive pink hue that is truly remarkable. The reason behind the pink color is still a subject of scientific research, but it is believed to be due to a pigment called protoporphyrin.
The Gouldian Finch is a popular bird among aviculture enthusiasts due to its stunning appearance and unique breeding behaviors. However, it is important to note that this species is currently listed as endangered in the wild, primarily due to habitat loss and changes in the landscape.
Efforts are being made to protect and conserve their natural habitats to ensure the survival of this beautiful bird.
Zebra Finch
The Zebra Finch is another species that surprises us with its pink eggs. Native to Australia, this small finch is known for its distinctive black and white striped plumage, hence its name. The female Zebra Finch lays an average of four to six eggs per clutch, and these eggs have a pale pink coloration.
While the exact reason for the pink coloration of Zebra Finch eggs is not fully understood, it is believed to be related to the diet and genetics of the bird. The pigments present in the food the female consumes, such as carotenoids, can influence the color of the eggs.
Additionally, genetic factors may also play a role in determining the shade of pink.
It’s important to mention that not all finch species lay pink eggs. Most finches, including popular pet species like the Society Finch and the Canary, lay eggs in the typical white or pale color range.
The pink eggs of the Gouldian Finch and Zebra Finch are special and unique characteristics that make these birds even more intriguing.

Terns That Lay Pink Eggs
Roseate Tern
The Roseate Tern is a beautiful seabird known for its pinkish eggs. These elegant creatures can be found in coastal areas around the world, including North America, Europe, and Africa. With their long, slender wings and distinctive forked tail, they are a delight to observe in flight.
What makes the Roseate Tern truly unique is its ability to lay eggs with a pink hue. The color of their eggs is believed to be a result of their diet, which primarily consists of small fish, shrimp, and other crustaceans.
The pigments from these marine organisms are then deposited in the shells of the eggs, giving them their rosy coloration. It’s nature’s way of adding a touch of pink to the world.
If you’re lucky enough to catch a glimpse of a Roseate Tern nest, you’ll be greeted with a sight that is both fascinating and adorable. The parents take turns incubating the eggs, with both the male and female sharing the responsibility.
This cooperative breeding behavior is just one of the many fascinating aspects of these remarkable birds.
Common Tern
Another member of the tern family that lays pink eggs is the Common Tern. As its name suggests, this species is more widespread and can be found in various habitats, including coastal areas, lakes, and rivers. Common Terns are known for their graceful flight and distinctive black cap on their heads.
Similar to the Roseate Tern, the pink color of the Common Tern’s eggs is a result of their diet. These birds primarily feed on small fish and invertebrates, which contain pigments that are transferred to the eggshells during the laying process.
The pink eggs of the Common Tern provide a visual treat for birdwatchers and nature enthusiasts alike.
It’s interesting to note that not all tern species lay pink eggs. Some lay eggs that are speckled or spotted, while others have eggs that are plain in color. Each species has its own unique reproductive strategy, and the color of their eggs is just one fascinating aspect of their biology.
