Death on the roads

.

SAFETY FIRST

Dead hedgehogs lying in the road cause much concern among hedgehog-lovers - and much controversy too.

Either it means that hedgehog numbers are being depleted by these casualties, or that the population must be vigorous to provide a continuous supply of victims.

It has also been suggested that hedgehogs are gradually learning not to roll up in front of cars, but to run for it, and that the 'runners' survive and pass on their genes to future generations. But the 'runners' are just as likely to be squashed as the 'rollers-up', as they will probably find themselves in the path of one of the car's tyres.

Hedgehogs can run quite fast, but not fast enough to avoid a car; and rolling up is no defense against four wheels.

In any case, there has been too little time, in evolutionary terms, for the hedgehog to adapt its way of life to the presence of the internal combustion engine, I think!
