 Common starlings prefer urban or suburban areas where artificial structures and trees provide adequate nesting and roosting sites . <unk> are also favoured for roosting and the birds commonly feed in grassy areas such as farmland , grazing pastures , playing fields , golf courses and airfields where short grass makes foraging easy . They occasionally inhabit open forests and woodlands and are sometimes found in shrubby areas such as Australian <unk> . Common starlings rarely inhabit dense , wet forests ( i.e. rainforests or wet <unk> forests ) but are found in coastal areas , where they nest and roost on cliffs and forage amongst seaweed . Their ability to adapt to a large variety of habitats has allowed them to disperse and establish themselves in diverse locations around the world resulting in a habitat range from coastal wetlands to alpine forests , from sea cliffs to mountain ranges 1 @,@ 900 m ( 6 @,@ 200 ft ) above sea level .
