Every organism has specific characteristics that make it ideal for living in the certain environment that it resides. For example, owls are birds that have adapted to hunting at night. They have many adaptations that allow them to be successful night hunters. One adaptation that the owl ...view middle of the document...

Another special characteristic of the owl that makes them excellent night hunters is their acute hearing abilities. Owls have very large ear openings and cochlea that are covered by feathers. One ear is even higher than the other so that the owl can turn its head to make a sound’s intensity equal and thus hone in on where the sound is coming from. Even their feathers have adapted to assist in the hearing of their prey! An owls wing, leg, and body feathers are extremely soft so there is no rustling sound from their movements to interfere with the noises their prey makes.
The owls’ digestive adaptations are also fascinating. Owls’ do not actually chew their food and instead swallow them whole or rip them into pieces using their talons and beak. Different from other birds, owls do not have a crop which is a loose sac in the throat that can store food for later consumption. The owl can also produce pellets to rid themselves of the indigestible parts of their prey. An owl’s pellets differ from other birds of prey because they contain a greater proportion of food residue. This happens because the owl’s digestive juices happen to be less acidic than in the other birds.
Owls are fascinating creatures and have adapted extremely well to their environments. From head to toe and even the stuff on the inside, an owl is well adjusted to survival in its environment.
