[StevenA]

I have had my v3 cameras in the same spot for a year and a half. Only once has it captured a bird flying close to it in all that time. See my video on this link from 5/16/2023. Thanks again to TomG for the Slow-Mo version below my video.

Rarely do I get to post a bird video. Let alone an action shot.
