Birds' vision

Postby alan refail » Mon Oct 08, 2018 1:27 pm

It has always puzzled me how hens and ducks are so aware of what is directly in front of them, not just feed but the tiniest tasty insects, even thought their eyes are on each side of the head. After a little research I came across this very informative article, which goes some way to enlightening me.

Why do birds differ in how they can see through glass? Twitch an eyebrow and a member of the crow family will fly away but you can move about and point at most of the small birds like tits, robins and sparrows. We had a goldcrest last Winter that spent ages pecking round our front door that you could watch from two feet away.

Birds came from raptors so I expect this is one of the adaptions that made the dinosaurs so successful in their time!

Chickens also have the ability to sleep with one eye open and the other closed. During this form of sleep, unihemispheric slow-wave sleep (‘USWS’), half of the brain gets a rest whilst the other remains awake and alert for predators.

A chicken’s brain is divided into two hemispheres. Each eye is attached to the opposite hemisphere, i.e. the left eye is attached to the right hemisphere and the right eye is attached to the left hemisphere. Chickens can be asleep and awake at the same time!

Geoff, I think the goldcrest you were watching was so intent on getting rid of a rival which it saw in your window reflection that nothing else mattered. We have had a goldcrest doing that on the wing mirror of the car and stood next to it, in touching distance, and it has continued pecking at this supposed rival.

You guys are all so knowledgeable - might not be many on here but what there are can generally answer any question asked - shame so few are brave enough to ask though! But I for one am getting an education that is so diverse! Cheers with the duck & chicken vision - amazing!
