Robins ground foraging describes the foraging behavior of robins, a group of thrush species known for feeding on the ground for invertebrates and fruit. In North America, the American robin (Turdus migratorius) is a typical example; in Europe, the European robin (Erithacus rubecula) also exhibits ground-foraging habits. The behavior involves hopping or running across open ground, especially lawns, borders, and leaf litter, while the bird pecks or digs at the soil with its bill, sometimes flipping leaves with a swift flick of the head to uncover prey. A primary prey item is earthworms, which become exposed after rain when the soil is moist. In addition to worms, robins target insects, spiders, snails, and occasional fruit or berries, with diet shifting seasonally from invertebrates to fruit in autumn and winter.

Robins use acute vision and keen hearing to locate prey below the surface. They often listen for worm movement, then strike and pull prey to the surface. Ground foraging is a common daily activity and is most intense during the breeding season when chicks require protein. While robins also catch insects in the air, ground foraging constitutes a major foraging strategy in many habitats, including urban lawns and parks. The practice supports ecosystem functions by regulating soil invertebrates and recycling nutrients.

Human surroundings influence ground foraging: well-mowed lawns with sparse leaf litter reduce hiding places, while patches of mulched beds and moist soils can increase prey availability. Robins are adaptable and widespread, and ground foraging remains a defining aspect of their behavior.
