In the Race
Now, here, you see, it takes all the blogging I can do to keep in the same place.

You see, I'm in

If you ever find yourself lost in a field or in the woods…and don’t have a compass, moss on a tree or your new GPS…don’t fear…
Look to the animals to point you in the correct direction...they are able to sense magnetic fields.
This is a pretty cool article…
Have you ever noticed that herds of grazing animals all face the same way?
Images from Google Earth have confirmed that cattle tend to align their bodies in a north-south direction. Wild deer also display this behaviour - a phenomenon that has apparently gone unnoticed by herdsmen and hunters for thousands of years. In the Proceedings for the National Academy of Sciences, scientists say the Earth's magnetic fields may influence the behaviour of these animals. The Earth can be viewed as a huge magnet, with magnetic north and south situated close to the geographical poles. Many species - including birds and salmon - are known to use the Earth's magnetic fields in migration, rather like a natural GPS. A few studies have shown that some mammals - including bats - also use a "magnetic compass" to help their sense of direction.
