question about bird flight patterns
For any ornithologists/bird enthusiasts here: I'm curious to know if there is a behavioral explanation for starlings and pigeons flying in patterns as a group. Sometimes they do it in huge numbers, sometimes a couple break off from the larger group and fly in smaller groups alongside the others, and when I see it happen, it last a couple of seconds at a time. When viewed in large enough numbers from a distance, they look like fabric blowing in the wind and I think it's fun to watch them. But why do they do it?
