I love when my cams see multiple mountain lions at the same time. In this video, a mother mountain lion checks out an area with scrapes left by male lions. As she's checking it out, she gives a bird-like chirp to call her kitten (at about 1:07). The kitten is big - almost full grown but he comes when called. What a gift to get to see them!
The video is short. Please check it out if you have time.
