Ever wonder how birds can tell which eggs are home to their chicks? Well it all has to do with the colour of the egg. Now, I know what you may be thinking, all birds have eggs look the same! And you know what, you are right. Bird eggs all look the same…to humans.

Researchers have discovered that birds have the ability to see ultraviolet (UV) light, which humans cannot. This could explain how, when a white egg looks like every other white egg to us, birds can see distinctive markings and can tell which ones have their chicks.
