The barn owl has the most developed sense of hearing of all birds.
Barn owls are very effective hunters thanks to a combination of forward-facing
eyes, ten times the light sensitivity of humans, great depth perception,
and a neck that can rotate up to 270 degrees. Serrated feather tips muffle
the sounds of flapping wings during flight, allowing the owls to swoop
down on unsuspecting prey. Camouflage coloring protects the owls from
predators during the daytime. Barn owls do not construct nests, instead
surrounding their eggs with pellets made of the regurgitated bone and
fur fragments of their meals.
