Human detection only for Alerts but not for Detection

What I want is very simple, I would like to enable human detection feature for alerts as I don’t want to get an alert every time a bird is on my backyard. But I still want the camera to record when it detects some movement as there might be some animal that breaks into my backyard, destroys something or whatever, if I have a camera I want to be able to check what happened. By now I can find a mess in the backyard but never know what happened because no human was detected.
