Bobcats Are Back

We have not seen a bobcat on our cameras since March. Since October 1 they are officially back in the yard. I think we have at last three or four individuals. What do you think? Please let me know in the comments section.
The last three clips are a bit of a mystery. Based on the markings and the size I was sure this was a mountain lion. However, lions have long tails. This one has tufted ears and a short tail, but boy is it big for a bob cat. Thoughts?
