How to identify birds eggs? And how are humans 'like' eggs?

How do scientist or bird watchers identify bird eggs?
- by anatomical comparisons and also using molecular tools.
What does an amateur needs to identify the eggs of different bird species?
-anatomical comparisons or a careful look at the egg morphology: egg color, size, and texture.
-In addition you need to learn about the behavior of the birds, nesting habits, type of preferred habitat and so on.
-a good actualized birds egg field guide.
-a lot of practice!
Imagine that you could see just an egg and say, this is a crane, a parrot, a woodpecker, a tern,or an specific species of owl? Wouldn't it be impressive? And you may wonder what is that for? How can it help anybody?
Because several species of birds have been treatened by human ways--habitat destruction or change, pesticides, illegal trades, and yes even egg collecting, some species of birds are protected. In the United States, the Endangered Species Act is the regulation that have been brought about to protect these species and their habitats. If you like to know more about endangered species please see the UICN Red list of threatened species; or endangered species -The global list of endangered species [earth endangered species]
Collecting birds eggs is against the law for many birds. As for those that are not protected, think about it twice or as many times you need. Why would you need their eggs? It is expensive to produce eggs. It takes a lot of energy...and they do it with the hopes to pass their genes. Let those eggs where you see them. Let them become new birds, part of the food chain or rotten eggs.
If you come across one endangered species eggs, take a picture and an information about the site. Many phones allow you to save the location. Inform your local Audubon chapter and write a petition to establish protected that particular area.
