UFO Sighting in Oakhurst, California on 2017-06-06 15:07:00 – Rapid flight across my video

The following exert is an eye witness statement. Please read into it what you will. This has been reported to mufon who I am sure are investigating:

I was taking video of water falls in yosemite national park. i first notice the object in my video when i viewed it that evening. i thought i had accidentally caught a ufo on my video. it is high in the right side of the video and when i play the video it streaks across the top right corner of the video instantaneously from left to right! i was ecstatic when i saw it! it streaks so quickly out of view i figured it had to be a ufo! but my suspicion is that it is a bird at just the right angle and speed to look suspicious??

please view it and tell me your findings?

thank you for your time!
