You don't have to travel far to shoot decent wildlife photos. Other than spending some time practicing at the zoo or with your pets, why not take your camera to a nearby park or hiking trail? Birds and squirrels and lizards and the like may not be as charismatic as zebras or pandas, but they make for interesting…

In Southwestern France, a group of European catfish — which can get between 1 and 1.5 meters long — have taught themselves the art of fowl hunting to satisfy their discerning paletes.

It turns out crows aren't the only birds with fiendishly powerful memories. Pigeons are also capable of spontaneously remembering which humans mistreated them, and even an attempt to disguise the identity of their one-time abuser can't fool them.

It might not be immediately obvious just how birds could evolve something as complex as the wings needed for flight. But that's just it: flight was basically incidental to the real adaptation. The secret is a little something called flap-running.
