European Starlings were first introduced into the country in Central Park in 1890. Fiftly years later they had mulitplied and spread to cover all of the United States and the Southern part of Canada. They are a gregarious and very aggressive bird. I have seen them chase all the other birds from the feeders, then just get into it and scatter the seed all over the ground!!
Starlings normally feed in flocks, and they will eat almost anything, from seed to insects to fruit on the bushes. Because they eat almost any kind of insect and larvae, they can be very beneficial to the farmer and gardner.
They live the year round in the continental United States.
