Bird migration decline noted in southern Finland this autumn

This autumn, southern Finland is experiencing an unusual quiet in terms of migratory birds, with arctic species notably absent. According to Antto Mäkinen, vice president of the Kymenlaakso Ornithological Society, there have been very few sightings of arctic geese along the southern coast, which is surprising for this time of year. The warm weather and predominant southerly winds are believed to be significant contributing factors to this stillness. Mäkinen points out that northern Finland has not experienced many cold snaps that typically prompt birds, which have spent the summer in the north, to start migrating south for the winter.

As of this period, approximately 50,000 white-fronted geese have arrived in Finland, a notably low number when compared to the hundreds of thousands usually seen in the East and Southeast regions by this time in autumn.

The migration spectacle is typically vibrant in the fall, particularly since many fledglings join the migration alongside adult birds. Mäkinen suggests that many birds will remain in the north as long as suitable conditions prevail. The birdlife is often calmer in the north compared to the busier southern areas filled with people and habitation.

While some smaller birds have begun their journey south, larger migrations, like that of the cranes, are expected soon. Moreover, the impact of a milder autumn on wildlife varies—while some species may struggle, many migratory birds follow an instinctive calendar for their migration rather than reacting solely to weather changes. Adaptable species like arctic geese modify their journey as needed, while smaller birds benefit from abundant food sources currently available.
