Do any birds fly in a straight line?

Yes, some birds can fly in a straight line, particularly when migrating or traveling to a specific destination. Species like geese and swans often fly in a V formation, which helps them conserve energy, but they generally maintain a straight path toward their destination. However, their flight paths may vary due to wind patterns, obstacles, or the need to adjust for food sources. Overall, while many birds can fly in straight lines, their flight patterns are often influenced by environmental factors.
