Colony nesting is a reproductive strategy in which many pairs of birds build their nests in close proximity, forming large, dense groups known as colonies. This behavior is common among several bird families, including many Pelecaniformes like pelicans and cormorants. Nesting in colonies can provide significant advantages, such as enhanced protection from predators due to the collective vigilance of many adults, increased opportunities for social interaction and information exchange about food sources, and improved reproductive success through coordinated breeding activities. However, colony nesting also comes with challenges, such as increased competition for nesting sites and resources, and a higher risk of disease transmission within the densely packed group.
- Colony nesting involves many bird pairs nesting close together in large groups.
- Common among Pelecaniformes and provides benefits like protection and social interaction.
- Challenges include competition for resources and disease risk.
Enhanced protection from predators and improved access to mates are key advantages of colony nesting.
The order Pelecaniformes is known for colony nesting.
