Why do starlings do this?
The science behind murmurations

If you ever see a cloud of starlings moving together in swirling patterns in the sky, this phenomenon has a name... a murmuration. Here's more on why starlings form these incredible patterns in the sky.

Starlings are small-to-medium-sized birds found in the United Kingdom and in the United States. Scientists theorize that starlings form murmurations for several reasons. Primarily, these aerial displays are thought to serve as protection against predators. When starlings gather in large groups and move together in these intricate formations, it confuses predators such as hawks or falcons, making it harder for them to target a single bird.

Scientists also believe that murmurations might aid in communication and information sharing among the flock. They could convey information about food sources and navigation, or strengthen social bonds within the group.

Cooler temperatures may also play a role in these incredible displays. One hypothesis centers on body heat. A murmuration can attract other starlings in the area to one central roosting site. During the colder months, more starlings create a warmer roosting spot.

Scientists are still exploring the exact reasons behind murmurations, as the phenomenon involves complex interactions between individual birds and their environment. The synchronized movements are stunning to watch and show the remarkable coordination and collective behavior of these birds.
