I think that pitch recognition is not just based on vision distance quality, but also on some aspect of vision speed. Whoever said something about synaptical development in addition to 20/10 vision was on to something IMO.
Unreal, that would mean a great deal with reading spin of a ball.
Off topic on NPR today they had an hour long special on bird vision, and what they have been able to deduce from birds are they are basically seeing
1.) more colors due to a higher frequency range in the UHF range.
2.) Magnetic fields, this was found by covering a single eye of a european robin and then subjecting it to magnetic fields.
3.) Humans have one Iras while most birds have two giving them a telefocus ability...
