David – Coyotes probably have the biggest impact on smaller mammals such as mice and voles – the red fox niche – but I’m sure they put a hurtin’ on rabbits, too (forgive the technical eco-jargon there). As a matter of fact, our cottontail population here on the mountain has dwindled to almost nothing here in the last couple of years, but I have no idea whether that’s related to coyote population trends. I will say that neither the abundant woodchucks nor the resident feral cat seem to be having any trouble.
Actually, you know what’s really supposed to prey on rabbits? Bobcats. Which we’ve only been seeing here with any regularity in the last three years. Hmmm.
