Page 35 - The Miracle Of Talking Birds

Birds’ ability to perceive sound is approximately ten
times keener than ours. Birds can discern ten different
sounds in what humans perceive as one note. Moreover,
while humans process sounds in 1/20th of a second, birds
can distinguish the same sounds in 1/200th of a second.

each of this sense’s components is created by special
design, for if any one failed to work properly, the bird
would not be able to hear anything. This point also
disproves the theory that hearing evolved or emerged
gradually, as a result of coincidental influences.
