kekojärjestäminen

Kekojärjestäminen, a Finnish term, translates directly to "nest arranging" or "hollow organizing." It refers to a practice observed in some seabird colonies, particularly those of the Arctic tern (Sterna paradisaea). This behavior involves the birds systematically clearing and arranging small depressions or shallow hollows in the ground, often in gravelly or sandy areas. These arranged hollows serve as the nesting sites for the birds.

The process of kekojärjestäminen is thought to be a collective effort within the colony. Birds may spend considerable time and energy in selecting suitable locations and then modifying them. The precise function of the arrangement is not fully understood, but it is theorized to provide a stable and protected environment for their eggs and chicks. The shallow nature of the hollows might offer some protection from wind and predators, while also helping to retain warmth.

This organized nesting behavior is a fascinating example of cooperative behavior and site fidelity in birds. While it has been documented in certain Arctic tern populations, its prevalence and specific ecological drivers are still subjects of ongoing research. The term itself highlights the intentionality and structured nature of the nesting site preparation undertaken by these birds.
