After reading "Causes of Color- Color Vision in Birds", the five most interesting facts that stuck out to me were
1. Some species of birds can see UV light.
2. Changes in ambient light can affect birds' reproduction and fertility.
3.Birds' retinas are far more complex then humans'.
4.The world is not exactly how humans see it, other things are left invisible due to the human eye's limited range of vision.
5.How a more complex range of vision is such an integral part of birds' lives (for example, the need for birds that live in a tropical environment to distinguish food/prey from green canopies, the ability to see excrements of prey)
