Yes, it's a good point - it just looks awful so I suppose it registers. High levels of road-kill also indicate that there is enough of a species to become road-kill on a frequent basis. The wet Spring a few years ago caused a significant decline in some bird species, Barn Owls being among them. Biologists knew this because they were finding fewer road-killed owls. So anyway, that's part of the reason I said he "underplays" the road-kill effect, rather than using it as a way to outright dismiss his arguments.
