Owls provide another fascinating example, as some species initiate nesting in the heart of winter, taking advantage of the quiet and the availability of prey before other competitors emerge. Robins, often seen as a symbol of spring, typically begin their first nests in late winter or early spring as soon as they can secure enough worms and insects.
You may witness frantic activity near potential sites—cavity holes in trees, dense shrubs, or building eaves—as birds carry nesting material in their beaks. The subsequent incubation period requires one or both parents to keep the eggs warm until they hatch.
