Well, I sent the video to Cornell Lab of Ornithology . Below is their response:
“Hi Mila,
Thank you for contacting the Cornell Lab of Ornithology! I believe the hawk you spotted is a Swainson's Hawk. The footage you captured is beautiful!
Please let me know if you have any additional questions.
Best,
Caroline Stamm

It was filmed nearby of the first one.
