Thanks Kurt. I'm betting that fox or foxes are rabid.
Don't worry, it's not like I'm getting real close. Zoom lens & all that. I do love watching them though. It was great watching it hunt that morning. Those ears are amazingly sensitive. It was zeroing in on sounds you & I would never hear. They do the same spring up in the air arching their body & then diving on the prey as you see in this video.

I have seen this video a number of times on TV shows & such but I never knew they use the same springing/pouncing method even when there isn't snow.
