In Norse mythology, two ravens named Huginn and Munnin — "Thought" and "Memory" — employ these faculties as Odin's emissaries, acting as the god's eyes and ears on Earth and reporting back to him about whatever they observe. Even in common ravens, problem-solving, decision-making and remembering past experiences are traits that scientists recognize as highly developed.
Now scientists have found that ravens seem to know when they're being watched by a rival that might steal from them, and then take steps to hide their food.
Previous behavior studies with scrub jays, which are raven relatives, showed that they could interpret other bird's thieving intentions — if they spied another jay watching them while they had food, they hid the food away.
