- Hearing
- The hearing
of barn owls is extremely good because:
- The external
openings to the ears which are positioned on the
margins of the facial disk are of slightly
different size and one ear is slightly higher tan
the other.
- There is a
stiff line of feathers that forms the edge the
facial disk and these reflect sound towards the
ears
- The ear
openings are protected by adjustable flaps which
combined with the other features allow the barn
owl to judge the source of rustless and squeaks
on the ground with a high degree of accuracy.
Experiments have
shown that a barn owls hearing is an essential complement
to its vision when it comes to its nocturnal lifestyle
and when hunting in particular as it can locate its prey
in complete darkness by sound alone.
