How Do The Parrots Protect Themselves?

They fly away

The parrot has one of the best defenses of any bird, that is his beak. Their beak
can tear through skin and cause a lot of damage

There very powerful beaks.

Parrots, with their hooked bills, are pretty adept at
using those beaks for defense.  A macaw has the most powerful beak in
the bird kingdom and when they need to, they can break more than palm
nuts (a Hyacinth's favorite food).

Their feet have an iron grip and sharp claws/talons.  Once they
have a firm hold on something and the determination to teach it a
lesson, the offending animal ends up with some severe injuries and a
reason to run.

Many animals don't bother approaching a parrot though.  The
screech that pierces your eardrum also serves to frighten off even the
biggest predators.  For anyone who has cats or dogs sharing the same
home as a parrot, they've seen the way the animal bolts out of the room
when the bird lets a scream go.

  For the most part though, a parrots defense is avoiding the
situation altogether.  They live high in the tree tops, often in pairs
or family units, as well as flocks (sort of like a family living in a
town with neighborhood watch).  An adult bird's only real potential
predator is another bird; babies/eggs; however, are open to predation
by snakes and other animals that can climb into the trees.
