I’m a little suspect of that last study the more I think about it. If you aren’t able to identify 66% of the mortality that you’re trying to count then the potential for bias is ripe in the 33% that you’re reporting on. I don’t know this to be the case but lets just say that maybe its easy to pick out coon mortality but much, much tougher to definitely say ones been killed by an avian predator. If that were the case then the numbers being reported would be heavily skewed. It could be that the vast majority of that unidentified 66% is avian mortality.
