Causes of a detached retina. Retinal detachment usually begins with a retinal tear, or hole in the retina. When a small hole or tear occurs, fluid from the eye can seep into the space between the retina and the back of the eye, which peels the retina away further.

True parrots have a beak with a characteristic curved shape, the jaw with a mobility slightly higher than where it connects with the skull, and a generally upright position.
Parrots are found in all the worldâs tropical rain forests. Those same forests are also home to creatures that eat parrots. The main predators, or natural enemies, of parrots are birds of prey, such as hawks, owls and eagles, and large snakes such as pythons and boa constrictors. Snakes grab parrots when they are resting on tree branches, while birds of prey attack them when they are flying as well as when they are at rest.
