A starling is an indigenous bird in almost every place between the Arctic Circle and the Equator. They don't live in the driest deserts.
Flocking starlings are one of nature’s most extraordinary sights. Just a few hundred birds moving as one is enough to convey a sense of suspended reality. Below is a video of a flock of a starling murmuration, which is just another word for flock as it relates to starlings.
Nature is amazing!
