Golden Eagle flying above Hercules

Susana dT

Seen yesterday, Sunday 21st at 12:45 PM. I think immature Golden Eagle. I was surprised to see it flying above downtown Hercules while chased by a Red-tailed hawk. Then it flew east, over our yard, possibly to Fernandez Ranch Park. Bad video good enough for ID here (I had to use slow motion due to too much camera shaking):
