- It's no secret that most birds have outstanding vision, that far surpasses the ability of humans. Most are able to see 4 light spectrums: red, green, blue, and ultraviolet, compared to just red, green and blue for us. They have 2 fovea in each eye to give them sharp vision and excellent depth perception, whereas we only have one fovea in each eye.

Highly interesting and appreciated information.
Glad you enjoyed it!
Wouldn't it be great if we had glasses that allowed us to see the world in colour as they do, including UV.
Yes it would! That would be quite the experience.
Great research and presentation! Really enjoyed the video. 👍♥
Thanks so much!
I wonder if anybody has ever done a study on penguin underwater sight acuity.
That's a fascinating topic. Making a note of it!
Very informative video! Awesome work.
Funny how all thes superlative birbs are well-known.
Great video, thanks! I'd love to see how birds see, even for just a minute. It's kind of hard to imagine, but the imagining is part of the fun. (Have you read Ed Yong's AN IMMENSE WORLD? It's a great book about how other animals sense things and what their sensory worlds might be like, including seeing UV vision but also stuff like electrochemical sensing and sensing magnetism.)
Yes, I have thought that too! I just looked up that book and it looks really good. Thanks for the suggestion!
Do you know if there are any birds with a polarizing capability to reduce reflections on water for hunting?
