Do you know your Bird Eggs? [QUIZ 2]
Looking at each egg will make you wonder what advantages or disadvantages it might have. Take for example cliff nesting birds who building their nest on large ledges. Maybe those eggs which are more pointed are less likely to roll off the ledge because they will instead roll in a tight arch?? Why are birds eggs colored differently?? Maybe from a predator’s vantage those green or blue eggs could look like a hole in the vegetation?? Those birds with white eggs might not need to be camouflage because both parents take turns incubating the eggs while protecting the white coloring from predators?? Maybe cavity nesting birds require that white coloring so that the parents don’t accidently break the egg while in the darkness of the cavity?? Are duck eggs oilier than normal eggs to help keep them more waterproof? So many questions that are being looked at by ornithologist today and their findings are helping us understand the unique features in the development of these eggs.

By posting these two birdQUIZs, I am hoping you will also look closer at each egg and try thinking why each egg looks the way that it does. This exercise will help you finding the proper owner of the broken or hatched egg shell that you find laying on the ground. Good Luck with the quiz!! (more…)
