Hoot-hoot. Have you ever paid attention to the flute-like sound at night in the mountains near the suburbs? Look closely into the dark, and you may come across a night scops owl perching in a tree with their watchful yellow eyes wide open, waiting for the right moment to make a move. These small, camouflaged raptors feed on insects, lizards, and smaller birds. Long evolution and adaptation have made them one of the most efficient predators in the dark.
