I heard that Red Tailed Hawk making its territorial call before the Kingbird even started bothering the hawk! Interestingly enough, the hawk didn't make any sounds while the Kingbird was riding it. Once it flew past its head after flying to a nearby pole, the hawk made its calls again. I'd say this is rare footage, probably never seen again by anyone.

The hawk was probably startled into silence :P
