Webcam with motion detection?

I gave an old Acer Aspire (5610z). I installed Ubuntu Mate. I have an *old* webcam trying to get to work to record how a squirrel is getting into our bird feeder in the back yard.

I've read about "Motion", but can't get a GUI to show up?

Have also tried Cheese and OCS. None seem to do what I need. I can access the webcam with Cheese, but I don't think it does motion detection? OCS gives me an error "Failed to initialize video: unspecified error"

Am I at least on the right track?
