There, in the clear sky above them, were two ravens — but they were doing more than merely flying. Most of the starlings in Norway have now left for warmer countries. They majority migrate out in the course of October and they usually return by the end of March. Some spend the winter in Norway, especially along the coast. The reduction in the past 30 years has been about 400 million individual birds. The decrease of starlings can be part of the greater picture, as bird populations have generally been on the decline in Europe.
In 2008, scientists in Italytook on the time-consuming job of studying the flocks and blamed our ignorance of a flock’s movement simply on a lack of data. To combat this, the team used inter-linked cameras to measure how a flock works and took data from around 500 “flocking events”. Only 50 of these worked out well enough to be used . Crowd dynamics, the study of how crowds form and operate, sheds light on the tragedies and benefits of cramming lots of human beings together in a confined place. There is something moving about seeing so many individual birds unite in the sky as one. Within the murmuration, individual birds aren’t tightly packed together.
And they do all this while flying as fast as they can. The European or common starling, like many birds, forms groups called flocks when foraging for food or migrating. This special kind of flock is named for the sound of a low murmur it makes from thousands of wingbeats and soft flight calls. Birds, including starlings, mostly fly in flocks as a defence against birds of prey. 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. But starling flocks also fly in such formations when no predators are around, according to Dale.
We’ve created a new place where questions are at the center of learning. Britannica celebrates the centennial of the Nineteenth Amendment, highlighting suffragists and history-making politicians.

From the amazing cityscapes to the magical Thames river London can sometimes feel like a special place at times. Nothing sums up the city’s hidden power like a good video and one Londoner took to Reddit to share one that seems to capture the capital at its finest. “It is worth remembering that small birds have reflexes that exceed ours by a long shot. What we experience as an ultra-fast coordination of a flock of starlings is more of an easy tempo for the individual starling,” says Dale. I can just imagine trying to get decent shots as he drops toward the ground at such high speeds.
Seeing this in person definitely goes on my bucket list. Reminds me of the courtship flight of the Nighthawks. Male harriers Sky Dance for two reasons, to advertise their occupancy of territory and to court females. These two males could have been competing for territory or courting a female that I didn’t see. I got two consecutive shots with him fully in the frame but this is the only one that was sharp.
The birds, too many to count, danced around the sky in what seemed like perfect unity. There were no stragglers, each bird maintained their direction and kept up with the flock which moved at an incredible pace. We stared up at the birds and both wondered “how on earth do they do that? ” Their movement is so precise, so without fault yet so chaotic that it seems almost impossible that there could be so many birds all moving in such a beautifully collective manner.
I love your shot, and the video took my breath away. The researchers described the work as “the first large-scale study of collective animal behavior” and it cements the basic rules for collective animal movement. Each unit simply stays aware of these three rules and raja vikramarka review using their fast reflexes the starlings’ autonomy makes them united. Instead, scientists believe movements are coordinated by starlings observing what others around them are doing. Birds in the middle can see through the flock on all sides to its edge and beyond.
High quality DPI – clean beautiful & strong colors prints. In the early days of a new employee joining, exaggerate the small wins, recognize them and make them known to be “wins”. It’s difficult to say how long the two birds Lumley witnessed have been together, of course, but behavior like this is believed to be common among old and new pairings alike.
Then they use computer programs to track the movements of individual starlings and create 3D models of the flock. The birds are starlings, and the correct collective noun for them is “murmuration.” We’ve featured a similar video and some photos of the phenomenon here in the past. “When they gather to rest at night when spending the winter in Central Europe there can be several million touching down in a single forest area.
