What makes birds flock




















As far as we can tell, yes--it's still called a murmuration. Hopefully this article from the Audubon Society gives you extra information!

Thank you for sharing your experience with us, Stephen! We bet it was a pretty cool thing to watch! Hello, Mark Gillett! They do follow the starlings around them and scientists are still confused about how they know to follow the birds far away on the other side, especially since it seams to happen almost simultaneously. This would be a great topic to research more at your library. Hi, Robin. Thanks for your feedback. The quiz for this Wonder of the Day appears to have the correct answers programmed in, so we're unsure which questions you're meaning.

Could you email hello wonderopolis. Thank you, Wonder Friend! Thanks for letting us know what you thought of the video, Morgan! Hey there, Wonder Friend K Hobbs! Thank you for telling us how much you enjoyed our Wonder in flight!

We hope to see you again soon! WOW, that's an awesome question, Louise! We love the connection you made between schools of fish and murmurations! We hope you'll do some WONDERful research of your own about this cool formation-- we bet the library is a great place to start! Please let us know what you find! We're excited to Wonder with you!

It must be a very cool, and organized, thing to watch! We are so glad you shared your comment with us! Have we got a Wonder for you, Mrs.

Foster's Class! It's so cool to see in action, Kimberly! We bet it was very cool to see a murmuration while you were vacationing-- thanks for telling us all about it! We can't wait to find out what the next Wonder will be Hi there, Ayden! We appreciate your concern about the app-- we are working on making it better for all our Wonder Friends! We hope it will be better soon! Hi there, Berkleigh! Thanks for joining us on our Wonder adventure today, Blakeleigh! We Wonder if you have ever seen a murmuration?

See them often right in the sky above and behind our house, which is backed by woods. If they come too close the sheer number of them creates a LOT of dirt! I do love watching a murmuration though. Thanks, so much for your comment, Julia! We learned something new today. Steer clear of starlings if you don't want to get dirty! We are undergoing some spring clearing site maintenance and need to temporarily disable the commenting feature.

Have you ever seen a murmuration in real life? If not, don't worry. They're fairly rare. Don't worry, though. Some people have managed to capture some murmurations on video. Enjoy A Bird Ballet and marvel at the sight of a magnificent murmuration! Up for a challenge? Ready to give flight to your imagination? Now that you know what a murmuration is…and how little modern scientists understand them, we want to know what you think goes on between the thousands of starlings in flight. How do they keep from bumping into one another?

Do they all know each other's names? Do they talk to each other in flight? Or can they communicate with their thoughts? Do the starlings decide in advance what patterns they will form? Or do they make it up as they go along? Answer these questions as creatively as you can by writing a short story about a murmuration from a single starling's point of view. Tell your readers who you are and where you live. Describe what it's like to fly with thousands of other starlings that look just like you.

When you're finished, share your story with your Wonder Friends by posting it on Facebook. We can't wait to read what you write! Did you get it? Test your knowledge. When a falcon or another predator is close, the starlings congregate in the murmuration to put distance between themselves and the predator. How these murmurations move in such concise, synchronized movements has been the subject of much research through the years.

These groupings of birds and their movements involve a complex and not often observed scientific phenomenon called scale-free correlation, the Cornell Lab reports.

Basically, the birds in the murmuration move as one unit because each bird is influenced by the movement of all the others around it. Unlike birds flying in a V formation, which have an obvious leader, the starlings in a murmuration respond — almost instantaneously — to the birds around them, according to the Cornell Lab. If one bird moves to change course or speed, so do the other hundreds or even thousands of birds. The large-scale result of these correlated movements are the visual displays in which they bird appear to move as one.

By turning rapidly or simply tilting a bit on their axis, dunlins are able to shift the appearance of their plumage from dark their upperparts to light their underparts , creating a swift flashing effect that might startle or confuse predators. Falcons do go after tightly packed crowds of dunlins and other shorebirds, but those hunts are most likely to succeed when the attack causes a solo bird to stray.

Safety in numbers, in other words: Birds that stay together tend to survive together. Each member of a flock, he wrote, acts out of simple self-interest. When a predator approaches a flock, all the individuals in the group move toward the safest place—namely, the middle of the group—in order to reduce the chances of being captured. Observations of juvenile shorebirds have hinted that it may take them a while to get the hang of this, because they learn to form cohesive congregations only over time.

As they do, natural selection dictates that the birds least able to hang with the group are most likely to be caught by predators. Self-interest by itself may explain many of the observed dynamics of flock motion, such as density.

How, then, can they possibly know what direction to move in to avoid it? One clue came from studies of fish. In the s a Russian biologist, Dmitrii Radakov, tested schools and found that they can successfully avoid predators, as a whole, if each fish simply coordinates its movements with those of its neighbors.

Unlike linear flocks of geese, which do have a clear leader, clusters are democratic. They function from the grassroots; any member can initiate a movement that others will follow. It turns out that only three simple rules suffice to form tightly cohesive groups. Each animal needs to avoid colliding with its immediate neighbors, to be generally attracted to others of its kind, and to move in the same direction as the rest of the group.

They change density, alter their shape, and turn on a dime—just as real-world birds do. The makers of movies, from The Lion King to Finding Nemo, have used similar software to depict realistic-looking movements in large groups—whether stampeding wildebeest or drifting jellyfish.

By making movies of their flocks and analyzing, frame by frame, how each individual bird moved, he was able to show that a turn ripples through a flock just as a cheerleading wave passes through sports fans at a stadium.

This finding put to rest the old telepathy idea. Every year flocks of many thousands of starlings winter at large roosts in Rome. Thousands coalesce and form dense spheres, ellipses, columns, and undulating lines, sequentially changing the shape of their flocks within moments.

They exasperate many residents, who tire of the droppings they leave behind. Others love their elaborate displays. Some researchers had previously used high-speed stereoscopic photography to analyze the structure of the whole, but they were able to do so only with relatively small groups. Once a flock exceeded 20 to 30 birds, its structure became impossible to tease apart.

By using software borrowed from the field of statistical mechanics, which explains properties of materials by examining their molecular structure, Cavagna and other physicists have now been able to match up to 2, starlings in different photographs with one another. That allows them to map the three-dimensional structure of flocks much more precisely than has ever been possible before.

Onscreen, they can take what appears to the human eye as a solid, rounded mass of birds and learn whether it is in fact a ball or rather some other more complicated shape, such as a pancake, a column, or an open cup.
