Animal Factoid

I was reading something the other day about three magnificent raptors – the barn owl, osprey and peregrine falcon. 

These hunters are quite adaptable, capable of flying vast distances and are specialized hunters.  The peregrine falcon preys-upon small birds.  The osprey fetches fish from the lakes and river it calls its habitat and the secretive barn owl subsists almost exclusively on rodents.   

All three of these birds can be found throughout the world - a testament to their adaptability.  Nevertheless, a successfully adaptable as these birds are they are not to be found on the continent of Antarctica.  Evidence that there are limits on adaptability.

Coincidentally, you will find ants and dung beetles on every continent as well.  With the exception of Antarctica.
