What sound does an eagle make?

Eagles are popularly known for their weak long sound call, usually a series of high and soft-pitched sounds. The sound is mostly associated with the Eagle when it is ready for copulation.
The female may repeat a single soft, high-pitched note that has been described as being “unlike any other calls in nature”; it is believed that this is her signal of readiness for copulation.

Eagle also produces a low-pitched ‘kuk-kuk-kuk’ sound. 

Do eagles screech or scream?

Eagles either screech or scream.

When they’re in the trees, they make a screeching sound. Eagles sometimes scream for two purposes: to scare off predators and warning other eagles when they are in danger. Additionally, the eagle can scream as a way of asserting its dominance over a particular territory.
