The aerial ballet the birds perform while flocking is mesmerizing to watch. Birds, including starlings, mostly fly in flocks as a defence against birds of prey. Read the Norwegian version of this article at forskning.no. The starling populations have suffered setbacks and the bird is now considered to be “near threatened” on the national red list which Dale is currently working on. Peloton's hi-tech bike lets you stream live and on demand rides to your home - and it's one of the best examples of fitness technology out there - at a price. They have been known to use some harsh methods to rid themselves of the freeloaders, including attempts to blow up whole colonies with dynamite, according to Dale. Norwegian starlings tend to winter in Great Britain. Usually 4 eggs are laid and incubated by the female for 12-13 days. They spend the day feeding in smaller flocks but as dusk approaches, they fly to these communal roosts. “No, starlings are not flying like this to put on a good show for humans,” says Dale with a laugh. Do starlings fly south in the winter? But Dale says the general weakening of starling populations could be attributed to poorer access to good wintering areas in Southern Europe. A murmuration is when a bird mimics the movement of its neighbour, eventually spreading to all birds in the flock. He thinks this might have also impacted Norwegian birds. It's eye-wateringly expensive at $2,999, but Naim's Uniti Atom is a revelation, an integrated amplifier than makes it easy to stream music at a quality you've probably never heard before. The more individuals in a flock, the less risk for each bird of being the unlucky one who gets taken out by a hawk or another raptor. Is this the childhood home of Jesus Christ? A murmuration is when a bird mimics the movement of its neighbour, eventually spreading to all birds in the flock. If you are 13 years old when were you born? But starling flocks also fly in such formations when no predators are around, according to Dale. The National Geographic video above shows a flock of starlings in the Netherlands. Murmurations can last 26 minutes but some will twist and turn through the sky for up to 50 minutes, with up to 750,000 birds in a single mass. I don’t know whether it has a function at such times or they are just having trouble deciding where to land.”, “One might think there is a risk in being the first bird to touch ground, and there is a little commotion before the flock lands.”, "So this is not a case of birds engaged in an artistic performance?".

Their study indicated that the aerial formations made by the birds change constantly to give each bird an optimal view of the surroundings. Starlings build a substantial nest, mainly of grasses, in trees and buildings. There have been several possible explanations for how the starlings are able to do this.
