It's mid-winter, and a passing flock of robins suddenly drops out of the sky. A moment ago, the yard was empty of birds, but now it's full. They settle in a bush laden with fruits. When the robins pass over a fruiting shrub, those red berries signal like a neon sign on a restaurant. Time to stop for a meal!
