Starlings begin to roost in September but their numbers increase as November passes. The RSPB says:
They mainly choose to roost in places which are sheltered from harsh weather and predators, such as woodlands, but reed beds, cliffs, buildings and industrial structures are also used. During the day, however, they form daytime roosts at exposed places such as treetops, where the birds have good all-round visibility.
RSPB Website
Starling numbers have been declining because of ‘loss of permanent pasture, increased use of farm chemicals and a shortage of food and nesting sites in many parts of the UK.’ The Starling was the most popular bird reported in gardens, it has now fallen to fourth. Prior to the year 2000, the starling was regularly the most numerous species recorded in the survey. This year it is behind the house sparrow, the blue tit and the wood pigeon.
Murmurations
Early evening, up to 100,000 birds will rise above their roosts wheeling and turning in tight formations. Research suggests that they achieve this not by following leaders but by, each bird, making small adjustments in accord with the birds immediately around them. Scientists have been able to construct algorithms that mimic the movement of a murmuration. These will allow flocks of drones to be easily controlled on mass with implications for agriculture, aerial displays and warfare. (https://www.bbc.co.uk/news/science-environment)
Sacred Birds
Starlings were sacred to the Celts and were used for divination by the Romans. Their augurs scrutinised the geometric patterns made by the murmurations to interpret the will of the Gods. In the Welsh Mabinogian a starling appears in the story of Bran, God-King of prehistoric Britain and his sister, Branwen, who was married to the King of Ireland.
To cut a long story short, (a version of which you can read on my February 18th’s blog post here), Branwen was banished to the scullery. So she trained a starling to send a message to her brother. He took an army over the Irish Sea to restore her to her rightful state, but Bran was mortally wounded in the battle that followed. He told his companions to cut off his head and take it back to the White Hill, London. His head was as good a companion on the way back as it was on the way out, but the journey home took 90 years. At last, they got to London and his head was buried on the White Hill, near the Tower of London, and as long as it were there Britain was safe from invasion. This was one of the Three Fortunate Concealments and is found in ‘the Triads of the Island of Britain.’

Shakespeare and Starlings
Shakespeare in Henry IV Part 1 has Hotspur, annoyed with Bolinbroke say:
I’ll have a starling shall be taught to speak nothing but ‘ Mortimer,’ and give it him
Now if you think the idea of a talking starling is nonsense, have a look at this video.
