Pigments color eggs as they pass through the female bird’s oviducts. Bird age affects color density. As birds age, their eggs grow.

Bigger eggs have less pigment. Even egg-laying strain affects color. Blue birds hide. The color of freshly deposited blue eggs stays after brushing.

Why Are Bluebird Eggs Blue

Robin’s eggs, Blue Bird Eggs, and other Blue Eggs are that color for a reason. Biliverdin, a bile pigment, is crucial. This pigment makes bird Blue Eggs.

During shell production in the shell gland, pigments are added; they give the eggshell its final color. The oviduct, which serves as a bird’s uterus, ends at the shell gland.

The egg’s color depends on bile pigments. Bluebird eggs have powdered blue collars due to coloration. A bluish-green, brilliant cobalt blue, or bluish-white egg is also conceivable.

Here are some additional facts about blue bird eggs:

  • Blue birds typically lay between 3-7 eggs per clutch, depending on the species.
  • The female blue bird is responsible for incubating the eggs for about 12-14 days, while the male provides food and defends the nest.
  • Blue bird eggs are typically oval or elliptical in shape, with one end being slightly more pointed than the other.
  • The color of blue bird eggs serves as a form of camouflage, helping to protect them from predators. The eggs blend in with the surrounding environment, such as the grass or leaves in the nest.
  • Blue bird eggs are relatively small compared to the size of the adult birds. This is because the eggs need to be small enough for the female to lay and incubate them, while also being large enough to contain the developing embryo and provide nutrients.
