Starlings – Sturnus vulgaris. The European starling is considered a pest bird due to its ability to reproduce in great numbers and create huge flocks of thousands of individual birds. Starlings are recognized by their iridescent feathers. They tend to gather together on the ground where they methodically look for food items such as seeds, insects and worms. They have been known to rid entire lawns of insects such as fleas, caterpillars and all other insects (except for ants), when gathered in sufficient numbers and left to forage freely. They roost together at night typically in trees where they can create a great deal of noise with their calls and quite a mess with their fecal material. Limbs of trees where they gather night after night will appear white with the accumulation of feces. Deterrents are necessary to keep starlings from an area.
