Hi folks
 
I have raised this before, but following up John Cumming's "cool pictures" I wish to re-publish a borrowed photo (with the permission of the photographer "Booshkie", a regular contributer to the Birds in Backyards Forum).
 
It is by way of a challenge to the photographers and the mathematically minded amongst you, to see if we can work out how fast birds like the Sparrow and this Spotted Pardalote male can shake their heads.
 
The Pardalote conveniently has spots, which might possible be useful in working it out.
 
"Booshkie" has advised me that the camera shutter speed was set on 1/160th of a second.
 
A very nice ultra-close-up shot is also attached, for reference.
 
Cheers
