European Starling
Also known as common starlings, these birds were introduced in New York in 1890. The original 60 birds have now swelled to a population estimated at over 150 million, and these birds are a common sight across North America. Starlings can make a variety of noises from whistles and chirps to mimicking the calls of other species. They mostly feed on insects but will eat seeds, grains, fruits, and more.
