Starlings are not everyone’s favourites, especially in the USA, but I like them. They are gregarious birds, and while in the summer they live in small loose groups, during the winter months they join thousands of others into communal night time roosts, which can number several thousand birds, and then spend the day feeding in smaller flocks. The sudden disappearance of the starlings in the winter is caused by summer roosting sites becoming unavailable which forces them to relocate, resulting in the temporary abandonment of some feeding areas.
