Migration Map News


On the current migration map the autumn season started in mid-July. Our new Osprey named Tiiu has surprise us all as no previous Estonian Osprey has gone to western Africa. Seems Tiiu wants to stay in Cote d'Ivoire. 

The hybrid Spotted Eagle (mix between Greater and Lesser Spotted Eagles) Tunne started in July and used quite a different migration route to last year, flying first northwards, from Russian Kaliningrad oblast to Latvia and then stopping near the Bosporus in Turkey. Last year he wintered 750km westward, in Montenegro.


Our Black Stork, Raivo, was rather late with breeding this year and therefore started his journey south quite late too.  He made good time with his travels however and arrived at his wintering grounds in Near East, Jordan Valley by 15th September.  A new Black Stork on the map is from Slovenia, his name is Francek. Francek started to migrate in 8th August and took quite a dangerous route over southern Italy and Sicily. According to the data Francek stopped over in the Rosmarino River mouth in northern Sicily. Probably that was caused by stormy weather there, but after awhile Francek continued his journey. He is in now in northern Tunisia.

Our famous Crane Ahja 4, began migration on 24th Sept and moved from Estonia to Belorussia. It will be interesting to see where he winters this year as last winter he spent wintered in Ethiopia together with its parents.

Lesser Spotted Eagles (LSE) are migrating quite close to each other and the distance between individuals has shortened during migration to just two-three days. There are more LSEs on the map than earlier as satellite tags were being used to collect data about their home range and the migration data is extra information. For LSEs it is typical that they avoid crossing even short expanses of water and will ganerally prefer an overland route even if it is longer.  For example they don't like crodssing the Suez Gulf even thought he width is only 20-40 km, but fly round it, whereas Black Storks do not avoid Suez Gulf, but choose better weather and wind to make the crossing.

The Greater Spotted Eagle Iti started slowly migration nn 3rd October. There is still no data about Tõnn, probably our most famous bird during the years...
