It is when I read something like this that I have to wonder what the heck people doing research are thinking. Is this type of information really useful to anyone? Maybe it is, maybe it isn't. Who knows maybe Primos is going to come out with power lines you put on your property to help you find deer. I can see the commercials now.
The research probably can't be directly used for anything but it does give biologists/animal researchers more insight on how all animals use the earths magnetic field to navigate.
