Migratory birds arrive unusually early across Finland, breaking local records

Migratory birds are arriving in Finland in record-breaking early numbers this spring, following an abrupt shift from severe winter cold to warm early spring conditions, reports Yle.

Across the country, multiple species have set new regional arrival records. In Pirkanmaa, birdwatchers have spotted the earliest-ever marsh harrier (ruskosuohaukka) on March 13—nearly two weeks ahead of its typical arrival. Other species, such as the meadow pipit (niittykirvinen) in Hämeenkyrö and the osprey (sinisuohaukka) in South Karelia, have also been observed earlier than ever before.

The sudden warmth has accelerated migration, with birds that usually arrive later in spring—such as cranes and lapwings—already appearing in central and northern regions. In Siikalatva, Northern Ostrobothnia, a crane was spotted on March 8, possibly the earliest sighting ever recorded there.

Despite the local records, no national arrival records have been broken yet. Aki Arkiomaa of BirdLife Finland notes that while the transition from extreme cold was unusually rapid, Finland has experienced warm early springs in previous years.

However, the early arrivals face risks. A late cold snap could still bring snow, threatening birds that have migrated prematurely. Birdwatchers like Niklas Paulaniemi of the Pirkanmaa Ornithological Society advise keeping bird feeders stocked in case of sudden weather changes.

The mild conditions have also dispersed birds more widely, as melting snow has opened up feeding areas across fields. But with spring only just beginning, experts warn that late frosts remain a possibility.
