Colonial nesting is a behavior observed in certain bird species where multiple pairs nest in close proximity to one another. This social structure provides various benefits, such as increased protection from predators and improved foraging efficiency. Birds that engage in colonial nesting often rely on the safety of numbers to deter threats. Species like seabirds, herons, and starlings are known for this nesting behavior. They typically choose locations that offer safety and resources, such as cliffs, islands, or dense vegetation. By nesting together, these birds can also share information about food sources and environmental conditions.
