    A Voracious Grey Heron

    A grey heron, at Mikrolimni village of Mikri Prespa lake, flies away from the prying eyes carrying with his beak a big northern water vole (Arvicola terrestris). The heron is just looking for a calm spot to devour the rodent. Such a large prey requires, beyond great effort in carrying, special care in handling as its teeth can easily injure the bird. In this particular case the heron flew a few dozen metres, landed behind the reeds, and killed the vole with many sharp and powerful beak strikes. Although grey herons feed mainly on fish, they often attack other species such as rats, mice, amphibians, reptiles, small birds, even moles, which make up about 10% of their prey.
