What Kind of Birds Eggs are Blue

The bluebird is a medium-sized songbird with blue feathers. The eggs of the bluebird are pale blue. The eggs are about 1.5 inches in diameter and have smooth, glossy surfaces.

There are usually three to five eggs in a clutch.

There are a few different types of birds whose eggs are blue. The best-known blue-egg laying bird is probably the robin, but other common blue-egg layers include jays, kinglets, and waxwings. While the robin’s eggs are a uniform blue color, the eggs of other blue-egg-laying birds can vary from pale blue to deep blue.

The reason that some bird eggs are blue has to do with pigments in the shells. Birds that lay white or pale-colored eggs generally don’t have any pigment in their shells at all. Birds that lay brown or greenish-colored eggs usually have a pigment called biliverdin which gives the shell its color.

And finally, those particular few birds that lay blue eggs have a pigment called protoporphyrin IX. So why do different birds have different eggshell colors? Well, eggshell color can be important for camouflage.

White or pale-colored eggs are often easier for predators to spot, so they tend to be found in nests that are well hidden or difficult for predators to get to. Brown or greenish-colored eggs provide better camouflage against vegetation and dirt, so they’re more likely to be found in open nests on the ground. Blue eggshells provide good camouflage against sky and foliage, so they tend to be found in nests somewhere in between – not too hidden and exposed.

Whatever the reason for their color, bluebird Eggs make a beautiful addition to any nest!

What Kind of Birds Eggs are Blue

Many different species of birds lay blue eggs. Some examples include Bluebird, Blue Jay, and Indigo Bunting. The blueness of the eggshell is produced by a pigment called biliverdin.

Biliverdin is a byproduct of the breakdown of hemoglobin in the body and is excreted through the bile ducts into the intestines. It is then reabsorbed into the bloodstream and deposited in the eggshell during calcium carbonate deposition.

Robin Eggs

If you’re lucky enough to find a robin’s nest, you may also be lucky enough to find some blue eggs inside it! These small, delicate eggs are a beautiful sight, and such tiny things can grow into magnificent creatures. Robins typically lay between 3 and 5 eggs at a time, and they incubate for about 12-14 days before the chicks hatch.

The female does most of the incubating, while the male brings her food. Once the chicks hatch, both parents help feed them. The diet of newly hatched robins consists mainly of insects, which the parents catch and bring to them.

As they get older and more independent, they gradually start eating more fruits and berries. By autumn, their diet is mostly fruit. If you find a robin’s nest with eggs, enjoy the view but leave them alone!

It’s against the law to remove eggs from a wild bird’s nest, and disturbing a nesting bird can also be harmful to its health and future reproductive success. So admire from afar and let nature take its course.

Birds That Lay Blue Eggs on the Ground

There are a variety of birds that lay blue eggs on the ground. The following is a list of some common species: 

  • American robin.
  • European robin 
  • House wren 
  • Tree swallow
  • Western bluebird 

Mountain bluebird Some other, less frequently seen examples include the following:

  • Rufous nightingale thrush 
  • Indigo bunting
  • Blue grosbeak

All of these birds typically nest in trees. However, some will also build nests on the ground if no suitable tree is nearby. Most of these species are found in North America, except the European robin, which is found throughout Europe and parts of Asia.

What Bird Lays Green Eggs

The Green-Winged Teal is a small dabbling duck found across North America. This bird gets its name from the distinctive green stripe that runs down its wing. The Green-Winged Teal is a famous game bird, and many hunters pursue this species yearly.

This duck lays its eggs in small clutches of around six eggs. The female will incubate the eggs for about three weeks before they hatch. Once the ducklings hatch, they can fly within two months.

The diet of the Green-Winged Teal consists mainly of aquatic insects and plants. These ducks will also eat some small fish and crustaceans. This bird uses its bill to filter food from the water as it swims.

The Green-Winged Teal is one of the most widespread ducks in North America, and it can be found in various habitats, including marshes, ponds, and lakes. This species typically nests close to the water so the young ducklings can easily make their way into the water once they hatch.

What Kind of Bird Lays Blue Eggs With Brown Speckles

Many different kinds of birds lay blue eggs with brown speckles. These include the American robin, the common eider, and the king penguin. The bluebird is another type that often lays eggs with this coloring.

The blue egg coloration is created by a pigment called biliverdin. This same pigment is also responsible for the green coloration of some bird eggs. When biliverdin mixes with calcium carbonate, it creates a beautiful blue hue in many bird eggs.

The brown speckles on these eggs are typically caused by a protein called protoporphyrin IX, which gives them their characteristic rusty appearance. Birds that lay blue eggs with brown speckles generally do so because they live in environments with a lot of vegetation. The green color of biliverdin helps to camouflage these birds’ Eggs from predators, while the brown spots provide additional camouflage when the Eggs are lying on the ground amid dead leaves or other debris.

Blue Eggs Chicken

What’s the big deal with blue eggs? For starters, they’re gorgeous. The blue-green hue is eye-catching and unique, adding a whimsy touch to your egg collection.

But beyond their good looks, blue eggs also have a few other things going for them. They’re said to be richer in flavor than your average white or brown egg. This is likely due in part to the fact that blue chickens tend to be free-range birds that are allowed to forage for their food, resulting in a more robust diet (and, therefore, tastier eggs).

Blue eggs are also higher in omega-3 fatty acids than other eggs. This means that they’re delicious and nutritious – a true win-win!


Most bird eggs are white or light blue, but there are a few exceptions. For example, the eggs of the American robin are blue with brown spots. The eggs of the common cuckoo are pale blue with dark spots.

The eggs of the kingfisher are bright blue. Why are some bird eggs blue? The color may help camouflage them from predators.

The color may also help to keep the egg warm by absorbing more heat from the sun.
