Wow, this is great! Trivia, mmmmmmm....
Magik, that is quite right about birds sleeping. Studies have shown that ducks generally choose to sleep in a row, side by side. The highest ranking ducks sleep in the middle, and both sides of their brain sleep. The lower ranking ducks take the outside, and sleep with only one half of their brain, the other half keeps an eye open for predators. My parrot will sleep with one eye open if I leave the curtains open, because he is nervous about pigeons flying past.
Dundee Slaytern - there is still a big difference. What you are referring to in humans, is sleeping lightly, which people often do if in situations of danger. Unlike birds, which are physiologically very different to humans, there is no physical way that a human can sleep with the right or left side of the brain and not the other.
Charean - according to my eyebrows, I am a man. And women have sharper elbows so they can wake a guy up when he rolls over and goes to sleep
Some trivia of my own:
The collective noun for a group of Parrots is Pandemonium.
Feral rats potentially carry 2 diseases transmissable to humans, pigeons carry more than 10.
Birds can see ultraviolet light, and so they see other birds as fluorescent. A budgie's cheek patches are particularly reflective, and another budgie would see this as a flash of light. Similarly with Sulphur Crested Cockatoos - they are ground feeders, and when the 'guards' spot a predator they raise their yellow crest - the resulting flash of light is seen by the rest of the flock and looks like the light from a flare.
