  • Mallard ducks use their own feathers to insulate their nests.
  • Hummingbirds lay small, white eggs approximately the size of jelly beans.
  • Swiftlets build nests out of their saliva on cave walls and cliff sides.

There are as many as 18,000 species of birds in the world with varying nesting habits. Some build their nests in the tops of trees, while others nest on the ground. Some build their homes alone, and others build nests with a mate as part of the courtship process. Some birds lay colorful or speckled eggs, and others lay eggs with plain white shells.

Mallard ducks lay around 13 eggs and sit on them for almost a month.

Robin eggs are known for their bright turquoise color.

The color comes from a pigment called biliverdin. A 2012 study at Queen's University found that the brighter the eggs are, the more careful male robins will be while caring for them.

Female robins usually build the nest, but both male and female robins feed their young.


The babies leave the nest about two weeks after they hatch.

They move into nests that have been abandoned by other species of birds like crows, ravens, or hawks.

The birds can be found in southern Africa's Kalahari region.

Sociable weavers don't migrate, and some chicks don't even leave the nest at all.

The nests can hold up to 100 families of sociable weaves. Some nests have remained in use for over a century.
