Because too many comments are now contributing little new about wildlife, etc., that is, there is little information, analysis, or reasonable discussion. There are too many personal attacks. This is becoming a moderated forum, at least for a while.
If you send a comment, I will have to approve it before it appears. That might be quickly or take several days because I do enjoy the outdoors and I am involved with two conservation organizations.
I am also thinking of some other devices WordPress allows that might return the blog to a more reasoned discussion of these matters.
