Red-tailed hawks also communicate through body language. In an aggressive posture, the body and head of the red-tailed hawk are held upright and its feathers are standing up. In submission, the hawk's head is lower to the ground and the feathers are smooth. Red-tailed hawks also display many aerial behaviors. In the talon-drop, during courtship, they swoop down trying to touch one another with their talons. Undulating-flight is an up and down movement that is mainly used in territorial display. Finally, in the dive-display the bird performs a steep dive. This is also a territorial display.
Red-tailed hawks have extraordinarily keen vision, which allows them to detect prey movements at great distances. Enjoy!!!
