Birds Eggs

Birds eggs
If you find an egg you want to identify, you should consider the size, shape, color, and sheen (glossy or matte) of the egg itself. But you should also note the habitat that you find it in, the kind of nest they were found in, and the clutch size (number of eggs in the nest), in order to make the best identification.

How are bird eggs made?
Building the Egg An egg's story begins in a female bird's single ovary. When an ovum is released into the oviduct and fertilized, it is just a protein-packed yolk. The albumen—the gelatinous egg white—is added next. The blobby mass then gets plumped up with water and encased in soft, stretchy membrane layers.
