Once thought to provide a service by preying on garden pests such as slugs and snails, hedgehogs are now known to also prey on a wide variety of native species, including invertebrates, lizards, and the eggs and chicks of a range of native birds.

For example, 21% of hedgehog guts (each reflecting a single night’s feeding) from Macraes Flat, north Otago, contained native skink remains; a single hedgehog dropping from near Alexandra contained 10 McCann’s skink feet; and two separate studies have shown that female hedgehogs are three times more likely than males to have eaten native lizards.
