Bird's homes

[loobie]

Hi, I'm really intrigued at how a bird knows where home is, which tree has their nest in and how they know which way they have to fly to get to it? Anyone that can shed any light on this thanks.

I think it's still unproven but i'm sure that animals such as birds and insects use the earths natural magnetic filelds to navigate....almost invisible highways. I think the position of the sun is also important. But, like our houses, all trees are different so i would think they would recognise them as well as using geographical features to find their way home.

Meanwhile they are up in the trees saying 'How do humans find their way home'!!!  Just a thought!

I agree with andyjevs. I read that someone (can't remember the name) did some reaserch on that. They put these little helmets with(I believe were magnets) on the birds and it disrupted their natural navigation system. Like when you put a magnet to a compass, if you've ever tried that, that's what it's like.
