What Other Colors Can a Bird’s Eggs Be?

Author Note: As you might expect, the typical colors of bird eggs are neutral. Generally, the default color of all eggshells is white, and this is because it’s made up of calcium carbonate. The white can be different tones of white, from a more honeyed cream color to a more stark finish.

You may have even seen the commercial paint that is sold as ‘eggshell white.’ But there are more colors to an eggshell than white. In fact, eggshells can come in a variety of beautiful colors. However, no matter how varied the colors, the appearance is rooted in two pigments.

One is green, and the other reddish-brown and together with the underlying calcium carbonate can give rise to beautiful colors ranging from a dark deep blue to rich brown to an emerald greenish-white. The colors of eggshells form the underrated artworks of the natural kingdom.

Everything in nature has a purpose, so what purpose do the colors of an eggshell have?

Color for Camouflage

Aside from incubating new life in the form of developing embryos, eggs make a nutritious meal for many animals- even other birds. For this reason, eggs need to have an extra defense. This is where their color for camouflage comes in.

Bird eggs are a vital source of food for many creatures, including snakes, amphibians, and even other birds. Camouflage is extremely important when trying to protect one’s vulnerable offspring, and birds take full advantage of this.

Eggs that have neutral tones blend easily into the environment as they have similar colors to that of the nest material and therefore can even be laid on the ground and in open spaces (known as scrape nests.)To provide an extra layer of protection, birds will also decorate their nests with natural materials such as seashells or branches.

How Do the Colors Protect the Eggs from the Sun?

Sunlight can be extremely harmful to a bird egg, and the color can, and does, offer protection. The heat and radiation that is given off from the sun can damage the egg and can influence the incubation period as well as the development of the young, unborn chick.

When the heat from the sun affects the incubation period, and the development of the chicks is rushed, there are higher fatalities and a greater number of mutations. UV radiation (ultraviolet) will have less effect on a dark-colored egg, but a light neutral colored egg may be more at risk of overheating.

The heat from direct sunlight will greatly affect a darker colored egg, while a lighter colored egg is able to deflect some of that heat and stay cooler.

The geographic range of birds plays a major role in determining the coloring of their eggs. Generally, birds that live in an open and exposed environment that sees more sunlight will have lighter colored eggs. Birds that live in environments that are concealed and aren’t exposed to much sunlight will have darker colored eggs.

They have evolved over many generations to find the perfect balance between the best environment to lay their eggs in and the safest color. Birds in the same genus might have slightly different colored eggs because their demographics and habitat preferences differ.

Clues in Eggshell Colors

Eggs that are bright are a great indication that both parents and chicks are in good health; it indicates that the mother bird has a nutritious diet and that the hatchlings should grow up healthy and strong.

Nest Care Habits

Generally, you will find that parents who regularly leave their nests to forage and regularly leave their nests unattended will have eggs that are greatly camouflaged. In contrast, parents who rarely leave their nests will have eggs that are plain in color with little or no camouflage.

Mismatched Siblings

Eggs in the same nest that look dramatically different (shape, color, or/and size) could indicate a brood parasite. These birds, such as cuckoos and Brown-headed Cowbirds, allow other species to raise their chicks for them by laying eggs in their nests without them knowing.

The unsuspecting moms will raise them as foster chicks.

Why are Robin’s Eggs Blue?

The American Robin (Turdus migratorius) are actually a species of thrush. When the female is laying her eggs, she deposits a pigment called biliverdin onto the eggshells, and this is why an American Robin’s eggs are blue. Evidence suggests that the higher the biliverdin levels are, the healthier the female is, and the color of the eggs will be brighter.

Next time you are wandering in the garden and spot a robin, try to be quiet and calm and see if you can spot the robin’s blue eggs.

  1. A robin has laid her eggs in a nest she built on my porch light. I was trying to remove the nest when I saw the blue egg. I read it’s a federal law not to remove a nest with eggs so I left it. While sitting on her nest she has become accustomed to us opening the door and going in/out of our house. One day a robin scared me when he swooped at me as I was on the porch. This must have been the male being protective as the female just flies away a little distance away and watches us.

  2. We have 3 blue eggs in a nest the birds made in our bbq. The nest is very big. We have been watching the birds daily as they built it. 2 days ago we opened the lid and saw the eggs. Now we won’t open it until babbies are gone. The birds are definitely not Robins. They are speckled on their backs with black tails. Yellow beaks.

    1. Wow, are you me? I just opened up my bbq and saw the same thing. The nest they built takes up almost the entire inside of our bbq. I really hope they hatch and move out soon, as we are moving to a new house at the end of the month.

  3. I saw a nest under my deck and was in the process of moving it when I noticed 3 blue eggs. I just push the nest back in place.

  4. I’ve got a real doozy of a nest location. We recently found two blue speckled eggs in nest in a wreath on our front door. Then to our surprise another egg appeared yesterday to close out the hat trick!!!

    1. Are you serious? I have an old wreath by my front door and this is the second year I have eggs in the nest from last year. That funny.

  5. I noticed a downed nest in my yard today after seeing two large crows walking around. I looked at the nest and there are a couple of shelf fragments in it that are a pretty blue color. It was extremely windy here yesterday and I’m sure that’s probably why the nest came down out of my tree but I’m questioning, did the crows eat what was in the nest or were they maybe just looking?

  6. we found a nest in our boat where we keep our life jackets saw 1 egg the next week there were 3 blue aggs and a tiny baby bird we take the boat out but the nest is in a very sturdy place

  7. On August 2, I was trimming a small deciduous shrub and discovered a nest with 3 solid blue eggs. Is it a little late for birds to still be nesting?
