Mountain Owl Declared Nationally Extinct in Sweden Amidst Rising Ecological Concerns

The mountain owl, known as fjälluggla in Sweden and famous as the inspiration for Hedwig in the Harry Potter films, has been officially classified as nationally extinct in Sweden according to the latest data from the Swedish University of Agricultural Sciences (SLU). This development comes as part of a broader update of Sweden’s red list, which SLU publishes every five years to track species at risk. The last confirmed nesting of the mountain owl was recorded in 2015, marking an alarming end to its presence in Swedish habitats.

Biologist Mikael Svensson from SLU highlighted that the decline stems primarily from the collapse of small rodent populations, a critical food source for the mountain owl. This population crash has been linked to climate change, particularly the disruption of stable snow cover that rodents depend on for underground nesting. Alongside the mountain owl, other owl species such as the tawny owl have also shown significant declines and may now be considered nationally extinct, while species like the pearl owl and hawk owl have recently been added to the red list due to deteriorating statuses.

The updated red list identifies over 200 species as nationally extinct in Sweden, including diverse insects, plants, two mammals (wild reindeer and black rat), and eight bird species. It is important to clarify that national extinction in Sweden does not equate to global extinction; for example, the mountain owl still exists in Norway, though its population there is also struggling.

This outcome reflects wider ecological challenges and underlines the urgent need for conservation efforts to address the impacts of climate change on species survival in northern Europe.
