Similar legends exist in Hungary, the Czech Republic,[citation needed] Poland, and Russia.
In Norse mythology, the Nachtkrapp (Swedish: Nattramnen, Norwegian: Nattravnen) is depicted with no eyes which if looked into cause death.
The origins of the Nachtkrapp legends are still unknown, but a connection possibly exists to rook infestations in Central Europe.
Already feared due to their black feathers and scavenging diet, the mass gatherings quickly became an existential threat to farmers and gave rooks and crows their place in folklore as all-devouring monsters.
In the subsequent e-picturebook Year Walk: Bedtime Stories for Awful Children (2015), the fourth chapter is devoted to the Night Raven.
