Note: Starlings are well known for mimicry, rarely do two Starlings sound exactly the same.
Distribution:
Found right across Europe being resident through central areas and a summer visitor to Northern areas. In the UK Starlings are resident breeders however numbers are dramatically increased in winter by migrants from the North of Europe. The Starling is considered a red list species due to dwindling numbers in the UK.
Habitat:
A bird of farmland, parks, gardens and woodland. In winter the Starling feeds in large flocks on areas of very short grass often near cattle and sheep.
Notes:
A beautiful bird to see close up the Starling looks simply black from a distance. It is one of the only birds to probe the soil with it's bill open looking for it's primary food source which is crane fly larvae also known as leather jackets.
Starling nest in holes situated in trees or buildings.

In winter Starlings roost in flocks sometimes numbering thousands, they provide a wonderful spectacle as the move in murmurations across the sky in early evening.
