Polar Bears

Postby Event Horizon on December 27th, 2018, 8:19 pm 

I was pondering on these magnificent creatures, and it occured to me that I don't know how they navigate. Especially as they can swim up to 60 miles at a stretch.

The landscape is no good, it keeps changing. I don't think there is much sun, and the stars would, I think, be frequently obscured.

But they travel long distances. Do we know how they navigate?

Good question. It seems like it would be pretty challenging navigating a dense forest though too where you really can't see the horizon and path of the sun but at least in a forest you could leave your scent I guess. Half of the year there would be a lot of sunlight while the other half darkness.

One thought would be they just wonder following food sources.
Another thought is they got used to traversing the same routes that they were taught growing up.

Here you can follow them.

Maybe you can email them on that website form and ask. Would be neat to see their answer posted on the research page.

I pasted and copied my whole post exactly as it is here. I'm not sure I could frame it any better I think. Have E-mailed as suggested, and will keep an eye out for a reply. I will post whatever they send.

Cool (pun intended). I hope you get a response.
I have always wondered how radio collars interfere with attractiveness and courtship behaviors of animals such as the polar bears on that tracking website.

Maybe its just a bit of bear bling! No reply yet.

They might be puzzled as well now!

I now have the answer. We still don't know.
Good topic for a thesis perhaps.
