The common starling is an omnivore; during summer, it consumes many insects and earthworms, while in autumn and winter, it switches to berries, fruits, and seeds. The species obtains food on the ground or catches insects in flight, feeding on insects, earthworms, berries, fruits, seeds, coniferous cones, plants, beetles, flies, membranous-winged insects, butterflies, bedbugs, straight-winged insects, dragonflies, mayflies, and net-winged insects. The active hunting strategy involves searching for and obtaining food, with a daily food requirement ranging from 30 grams to 60 grams. Eagles prey on the species.
