Scientists have been trying to track the movements (no pun intended) of t
he emperor penguins down south on the antarctic ice sheets. A very simple way was just figured out to locate these tuxedo wearing birds. The penguins will usually cluster together in large colonies on the ice, I guess for protection, squak at each other, and do whatever it is they do other than standing around. These colonies could be seen from space, but since they would appear black, they could easily blend in with the background or shadows on
the ice. Easy answer? Just spot their brown smear of leavings on the ice! That reminds, me I have 3 cats I need to go deal with.....
