Rough, tough world: A sparrow clings on as a bully barges him out of the way at the feeder before pushing him away with his leg
A series of high-speed animal flight videos are producing an amazing glimpse aerial world most of us have never seen before.
Amateurs videographers, with a bit of luck, can use inexpensive digital cameras to turn blurred images into clear illustrations of animal and insect behaviour.
A Dutch programme named Vilegkunstenaars asked videographers and animal lovers around the world to capture nature in flight, digg.com reports.
They sent high speed video tools to amateurs and the results that came back were stunning.

Experimental zoologist David Lentink, of Wageningen University, said: 'Research into fruit flies has shown that when trying to escape, they first jump and then topple into flight before eventually gaining control.
'This film illustrates the same behavior in a larger fly, the main difference being that [this] fly is exceptionally quick in getting the whole maneuver under control.'
