Robins use a technique where they rub ants or millipedes on their feathers to act as a natural insecticide.

Before the kettle boils on Mothering Sunday, a robin is already at work. Spring is its busiest season, and parenting is in full swing. This bird may look small, but it runs a tight family operation. The female selects the nest site and builds a cup of moss and leaves. She incubates the eggs, staying put while life develops beneath her. Meanwhile, the male plays provider, delivering insects to keep her fuelled. Once the chicks hatch, both parents feed them every few minutes. No snooze button, no packed lunches—just beaks full of worms.
