Common Starling
Sturnus vulgaris

The Common Starling was introduced to Australia from Europe in the 1850s in order to reduce crop pests. However, much like the Common Myna, they quickly became pests themselves and spread out of control rapidly. They now occupy much of the country and can cause serious problems with displacing native species through competing for nesting sites and consuming all the food in the area. They form flocks that can truly massive and can quickly strip a field of crops. They are attractively coloured with irredescent plumage and are medium-sized at 20-22 cm in length. Due to their status as an agricultural pest, they are heavily hunted to prevent them from moving into Western Australia and annual culls occur all along the border.
