liikukausi

Liikukausi is a Finnish term that translates to "move season" or "movement season." It refers to a period, often during the transition from winter to spring, where there is a noticeable increase in the activity and movement of animals. This is a biological phenomenon driven by changing environmental conditions such as longer daylight hours, warming temperatures, and the availability of food resources.

During liikukausi, many species emerge from hibernation or their winter dormancy. For example, bears and hedgehogs become more active, seeking food after a period of fasting. Birds that have migrated south often begin their return journeys north as conditions become favorable for nesting and foraging. The increased movement is also evident in insect populations, with many species emerging from their larval or pupal stages.

The timing of liikukausi can vary depending on the specific region and the prevailing weather patterns of that year. Early springs can trigger an earlier onset of this active period, while colder or prolonged winters may delay it. This seasonal surge in animal activity is crucial for the ecological balance, as it plays a vital role in pollination, seed dispersal, and the predator-prey dynamics within ecosystems. Observing liikukausi provides valuable insights into the natural cycles and the health of the environment.
