The great blue herons are not ground feeders. They like fish, frogs, turtles, snakes, small mammals, shrimp, crabs, aquatic insects like dragonflies and birds.

Perfection! Fungi and no tRump

Are these ranched mink fed a carnivorous diet or kibble?

They are looking for food or digesting food. I have a frequent visitor who spends most of the day waiting and watching before spearing a fish, swallowing it headfirst and then waiting some more.
