Ancient etched hummingbirds on the Nazca Plain of Peru

The huge hummingbirds etched into the silt on the Nazca Plain of Peru back in 200BC -600AD are still a mystery.

The lines are meaningless at ground level, but from the sky, the Incan tribe designs can be seen easily.

Many of the geoglyphs are constructed using a continuous line which has led many scientists to believe that the people of these ancient cultures "walked" the lines to perform some ritual.
