vesikÿkseen

Vesikyykseen is a Finnish term that translates to "water dive" or "diving into water." It commonly refers to the act of a bird, particularly a seabird, plunging into water to catch prey. This behavior is characteristic of several species, including various types of loons (also known as divers) and some grebes. These birds are highly adapted for aquatic life, possessing streamlined bodies, powerful legs set far back on their bodies for efficient swimming, and dense bones that aid in diving.

The hunting technique involves the bird spotting a fish or other aquatic organism from the surface. Upon sighting its prey, the bird executes a swift and decisive dive, propelling itself underwater with its feet. The duration and depth of these dives vary depending on the species and the prey being sought. Some species are known for their deep and prolonged dives, showcasing remarkable underwater agility. The vesikyykseen is a crucial foraging strategy that allows these birds to access a rich food source unavailable to aerial predators. Their success in this hunting method is directly linked to their specialized anatomy and keen eyesight, both above and below the water's surface.
