On Tuesday, spring begins – daytime temperatures on the plus side across the country – Domestic

The slowed spring migration of birds is intensifying as the weather warms up.

Next week, the weather will look much springier this week, and the day’s maximum temperatures will be on the plus side for practically the entire country for several days, according to the Finnish Meteorological Institute.

– Spring starts on Tuesday. The westward flow begins and we get warmer air. It is clearly the conditions of spring, says the meteorologist on duty Juha Jantunen From the Finnish Meteorological Institute.

Usually at this time the maximum temperatures in the south are around five plus degrees, but next week in the west and south the meter may show 7-8 degrees.

– Clearly the weather type will change, Jantunen says.

Skiing is still possible in many places, as there is snow in much of the country. The snow-free areas are mainly only the southern part of Satakunta and Southwest Finland.

– Even in Uusimaa, there is still more than 20 cents of snow in general, in some places more than 30 cents, Jantunen says.

The greatest depth of snow was on Saturday morning measurements in Kainuu, Paljakka, Poland. There was exactly a meter of snow.

– It is one of the places where the snow melts away almost last, even though it is not even in Lapland, Jantunen says.

The rapid migration of birds has slowed down

Spring migration of birds began rapidly at the end of February, but slowed down over the past couple of weeks, says Birdlife Finland’s spokesperson Jan Södersved.

– There is no need to go further inland when there are still very few signs of spring, he says.

Indeed, spring migration of birds has not progressed far beyond the south and west coasts.

The migration thus began rapidly at the end of February, when a very warm southwesterly airflow blew. According to Södersved, among the earliest returnees were, among others, swans, tentacles and great bustards, which are usually the first returnees. When they don’t go far from Finland for the winter.

We have also received small numbers of migratory birds flying over the sea.

– Among the first ones, a few hundred arrived at the turn of February-March. Most of them probably stayed here, Södersved says.

There were also some feather jumps, and there have been at most a few dozen in the best places, especially in Southwest Finland.

– Forest geese have come to Western Finland, so that there have been up to thousands of them in some places in Satakunta and Southwest Finland.

Climate change has brought forward the spring migration of birds

This year, spring migration of birds is on a fairly normal schedule, looking at the 21st century. In contrast, compared to older periods, the move is significantly ahead.

– In a few decades, migration has clearly advanced, especially in the early spring. It shows climate change, he says.

“Plenty of new migratory birds to arrive next week”

According to Södersved, spring migration is triggered by the weather in the birds’ starting areas. When there is a warm and good headwind, then the birds set off.

– It was then that at the end of February it was almost 20 degrees warm in southern Sweden, and it certainly got thoughts for spring with the first migratory birds.

In Finland, spring migration is now concentrated in coastal areas, because most of the country still has a good time to go inland.

– If there are very snowy landscapes in front, then the birds will apply for the places without passing very far, Södersved says.

Better weather for the birds is expected next week, so an increase in migration is expected.

– If the weather is not completely different from what the current forecasts look like, it can be said with great confidence that there will be a lot of new migratory birds next week, above all more migrants in early spring. And their migration will be able to move further inland.
