Wings

These birds have adapted to use their wings to fly and get food somewhere else far off. They are strong and are used to get food as well as attack invading cardinals.

Beaks

These beaks have some special features that make cracking easier: The edges of the lower beak fit into special grooves in the upper beak. A bird with this type of specialized beak will use its tongue to maneuver seeds into the groove. When the bird closes its beak, the sharp lower beak crushes the seed's shell so the bird can eat the seed inside.

Cardinals feathers (like all other birds) help them to fly and there distinct red color comes from all the berries they eat.

Cardinal feet have 2 front facing toes and one backward facing toe to help it perch.

Cardinal Tails help them lift off the ground when they start to fly.

Behavioral

Cardinals cover themselves with ants to ward off lice and sometimes squash them and smear the goop on like sunscreen.

Despite cardinals being very protective birds they sometimes flock together to help keep on the lookout for predators.

Cardinals usually stay in one place all year round to protect the female and baby chick.

Psychological

Cardinals do not need much sleep, so it can watch out for danger at night. It will dive from bush to bush, diving at attackers.
