My Friday noon forecast about the arriving migration wave of cranes has been confirmed. Our sat cranes from this summer, „Loode“, „Liiva“ and „Paslepa“ that were hatched at Sõrve in Saaremaa, Liiva in Muhu and Paslepa in Läänemaa respectively started their migration in the morning of October 6, and „Mustakurmu“ from Põlvamaa in the morning of October 7.

„Loode“ reached the Ventspils area in Western Latvia from the Pähkla fields in Saaremaa (distance about 115 km) in only 2 hours, „Liiva“ reached the Kalnujai area in Central Lithuania from Muraja in Saaremaa in 5 hours (distance about 350 km) and „Paslepa“ reached Kerekenava, likewise in Central Lithuania, in 8 hours (distance about 400 km). „Mustakurmu“ reached Vinskini in Setumaa directly on the Russian border in less than one hour (distance about 40 km) and then stopped there without migrating farther.

On October 7th favourable flying weather namely only lasted in the morning when there was a weak western wind and slight clouds in eastern and south-eastern Estonia and it was dry and good visibility but at midday the weather changed. The wind veered to southeast (head wind) and it started to rain. We will see when he gets on from there because the head wind and rain have lasted until now. The only one who has not started the migration is crane ”Hauka” from the Otepää area who still stays in Keeni near Sangaste.

Of this year’s sat cranes who had left Estonia already earlier Aivar“ ja „Uko“, young cranes from the same clutch, who had reached Central Lithuania went on towards south and reached the city of Chelm in eastern Poland near the Ukraine border.

According to the current migration view it seems that the Sõrve cranes „Mati“ and „Loode“ and Muhu crane „Liiva“ migrate towards Spain, the cranes „Paslepa“, „Ivar“, „Aivar“ and „Uko“ to Hungary and North Africa and „Hauka 3“, „Mustakurmu“ ja „Ahja 5“ to Ethiopia.

In addition to the sat crane migration intense crane migration was observed on October 6 and 7 in Saaremaa and West Estonia including Kihnu, and a less numerous migration in eastern and south-eastern Estonia as predicted.

A great number of barnacle geese also arrived at and migrated past Matsalu!
