I think this is part of the issue of feral cats---they eat robins and other birds. I saw something like this in mexico. Heard a lady got bit by a rabid fox in 'doing it after dark rock creek park' (donald byrd song ) today---they say this shows wildlife coming back---well, i know 2 fox dens and watch the babies playing around.
friend left a message on my machine with the spring peepers.
