The direction of the light in a shot can make all the difference. From one side these birds looked almost black but from the other side, with the sun on their feathers you could see the metallic green and purple on their chest and the spots on the tips of their feathers.
The common starling was introduced to Australia in the 1850s to consume insect pests of farm crops. It was believed that they were also important for the pollination of flax. By the 1880s, established populations were present in the southeast of the country and by the 1920s, common starlings were widespread throughout Victoria, Queensland and New South Wales, but by then they were considered to be pests.
