A Raven mobs an adult Red-tailed Hawk near Ocean Beach. This Redtail seemed to have plenty of experience with aggressive Ravens and it shrugged off the challenges with aplomb. Considering the size and intelligence of Ravens, standing up to them is no small feat.
This juvenile Redtail decided to survey the beach, entering the realm of both Ravens and Gulls.
Almost instantly the chase was on, and the young RT had to take evasive action.
The Redtail flips upside down to defend itself with its talons and reveals a banded leg. Notice that while the body contorts, the head stays relatively level.
Now the Western Gull takes a turn mobbing our young friend. I love this comparison highlighting the different wing shapes and head/tail ratios of these two birds.
