Why do birds make shapes in the sky?
Predators are more likely to catch the nearest prey, so the swirling of a murmuration could happen as individual birds try to move toward the safer middle of the crowd. Scientists call this the selfish herd effect. Of course, the more birds in a flock, the more eyes and ears to detect the predator before it’s too late.
Why do birds do murmuration?

Where is the best place to see a murmuration?
They mainly choose to roost in places which are sheltered from harsh weather and predators, such as woodlands, but reedbeds, cliffs, buildings and industrial structures are also used.

“The birds may also flock as a way to find food in the winter, sort of a cooperative effort, but that is speculative,” he said. The birds all end up gathering in the same area as the sun goes down, a process called “roosting,” picking an isolated patch of trees where they’ll spend the night.
How is flocking made?
WHAT IS FLOCKING? The flocking process involves applying short monofilament fibres, usually nylon, rayon or polyester, directly on to a substrate that has been previously coated with an adhesive. The diameter of the individual flock strand is only a few thousandths of a centimeter and ranges in length from 0.25 – 5 mm.
Why do birds flock?
Flocking helps birds notice and defend against predators, as they can all look in different directions to see threats. In addition, if a predator should come upon a flock, it can be distracted and confused by the swirling bodies and have a more difficult time picking out a single prey bird to target.
What material is used for flocking?
Flock can be made from natural or synthetic materials such as cotton, rayon, nylon and polyester. There are two types of flock – milled and cut. Milled flock is produced from cotton or synthetic textile waste material.
