Budgerigars, or budgies, are small, vibrant parrots native to Australia, known for flying in massive flocks that can number in the thousands. These social birds form large groups to forage for seeds and water across arid and semi-arid regions. Their synchronized flight displays, with rapid, undulating patterns, help protect them from predators and find food efficiently. These flocks create a mesmerizing spectacle as they move together, showcasing the incredible coordination and social behavior of budgerigars.
