Thought you might like to see this drone that visited my parents a couple of weekends ago. The owner named it MEDUSA since the blades were like the snakes on Medusa's head from mythology. He put a couple of eyes glued on at one end and seems to help keep some of the birds away. He does keep 400 ft agl or less. Here is MEDUSA flying and Here's looking at YOU. Owner is trying to be a drone ambassador so people will not fear them or get aggravated at them easily.
