“It probably happens in the winter because their is power in numbers in terms of avoiding predators. “The crazy swirling effort by thousands at dusk is likely a way to confuse any nearby predators such as hawks and owls.”

Birds, including starlings, mostly fly in flocks as a defence against birds of prey. The more individuals in a flock, the less risk for each bird of being the unlucky one who gets taken out by a hawk or another raptor. But starling flocks also fly in such formations when no predators are around, according to Dale.
