The group is legislated to be nationally invasive alien species (National list of alien species)

The group of alien crows and jays is included in the national list of invasive alien species.

The group refers to the species that are not native to Finland but occur in Finland outside their natural range. The crows and jays which are nesting in Finland or stray here during migration journey are not invasive alien species.

Alien species refer to species that humans have inadvertently or intentionally introduced outside the species natural range. Species that naturally spread to Finland, for example as a result of warmer climate, are invasive species, and the provisions on invasive alien species do not concern them.

Invasive alien species may not be released into the wild, imported into Finland from outside the EU or from other EU countries, transported, transferred, bred or cultivated, disposed of, passed on, sold, marketed, or otherwise handed over.
