Do birds usually migrate in groups?
Most birds are gregarious during migration, even those that are usually solitary at other times such as insectivores and birds of prey. Birds, such as shorebirds and waterfowl, with similar habits often migrate together. Migrating flocks will often show remarkable cohesion. Traveling in large groups provides safety for individual birds by confusing predators and making it difficult to pick out a specific victim. A characteristic migratory formation is the ‘V’ of geese, ducks, pelicans, and cranes with the point turned in the direction of flight.
