Hi, Welcome to OpenStreetMap.

I think these paths ways are actually paths and should be tagged as such as per OSM guidelines. If they are not open to the public then the correct thing to do is add the tag access=private which indicates that there is no public access whatever, no other restriction tags are necessary. 

The ways should not have a description in the name tag, these tags should be changed to description=?  Lastly I wonder if you meant the description to indicate bird ringing, rather than bird riging.

Regards Bernard.
