Lovat River
Studies on the behavioural ecology of free ranging polecat–mink hybrids in the upper reaches of the Lovat River indicate that hybrids will stray from aquatic habitats more readily than pure minks, and will tolerate both parent species entering their territories, though the hybrid's larger size (especially the males') may deter intrusion. During the summer period, the diet of wild polecat–mink hybrids is more similar to that of the mink than to the polecat, as they feed predominantly on frogs. During the winter, their diet overlaps more with that of the polecat, and they eat a larger proportion of rodents than in the summer, although they still rely heavily on frogs and rarely scavenge off ungulate carcasses as the polecat does.
