Seabird colony

A seabird colony is a dense aggregation of seabirds breeding at a shared nesting site. Colonies range from scattered nests to vast, crowded assemblages on islands and cliffs.

Colonial nesting: A breeding system in which animals nest in groups at shared sites. Seabird colonies are a prominent form of colonial nesting.
Seabird monitoring: The systematic measurement of seabird populations, breeding success, or distribution over time. Colony counts reveal population trends and breeding outcomes.
Bass Rock: A volcanic island in Scotland that hosts a major northern gannet breeding colony. Its dense gannet population is a striking example of a cliff-and-island colony.
Nutrient cycling: The movement and transformation of nutrients through organisms and the environment. Guano and discarded prey move marine nutrients into terrestrial habitats.
Solitary nesting: A breeding arrangement in which individuals or pairs nest apart from others of their species. It contrasts with the close spacing typical of many seabird colonies.
Philopatry: The tendency of an animal to return to its birthplace or previous breeding site. Returning to familiar sites helps maintain colonies across breeding seasons.
Important Bird and Biodiversity Areas: Sites identified as globally important for conserving bird populations and biodiversity. Large or threatened seabird colonies can help qualify sites for recognition.
Skomer Island: An island off Wales known for breeding seabirds, including Atlantic puffins and Manx shearwaters. Its varied nesting habitats support several prominent seabird populations.
Island biogeochemistry: The chemical cycling of elements in island ecosystems and their surrounding environments. Seabird-derived nutrients can alter island soils, plants, and coastal waters.
Lek mating: A mating system in which males gather at display sites while females visit to choose mates. Leks are social aggregations for courtship, not shared breeding and nesting sites.
