In 7th August 2008 he was ringed(white plastic ring 7F )and equipped with transmitter
By DNA test he was verified as pure GSE as well as his mother Iti, also well known for our forum, who was equipped with transmitter in year 2009.
In year 2010 Tõnn´s home-nest was known as only place where both, female and male were GSE. It exists till now and Iti has had several offsprings.
Tõnn started his first migration in 25th September 2008, crossed several countries and stopped for wintering in Spain, El Hondo wetlands which has been his wintering place till now.
As rare species in Estonia and other countries he excited great interest among ornithologists in countries he visited during migration. In total he has visited 15 countries. There spent winter and left his wintering grounds on April 13th and got himself moving in a northern direction. So the eagle visited also Nederlands and directed by the sea - moved towards to homeland. But Estonia was not a destination for Tõnn - he flew to Finland and spent all the summer near Vaasa (western Finland). On second fall migration Tõnn stopped also in southern Estonia, during a harvesting of crops. Afterwards moved again to Spain, crossing a Switzerland as a new country for him. Third summer Tõnn spent mostly in Sweden and used migration route directly over Danish straits.

Migration 2008 - 2014
After 2014 transmitter stopped working but we knew that Tõnn was alive and well from several places he was spotted.
In spring 2016 during the spring camp member of Eagle Club Renno Nellis found a breeding Greater Spotted Eagle in Harjumaa county and for surprise with transmitter on back. To get information about the tagged male eagle, Eagle Club members caught it in the beginning of September and it appeared to be our old fellow Tõnn. So Tõnn started to breed either in 2015 (then not in the same place, because there was nesting Lesser Spotted Eagle in 2015) or rather in 2016 and was also successful. A mate of Tõnn has no rings, therefore we don't know her origin.
Old transmitter was removed and as there wasn´t damages on the skin, new refurbished transmitter of Ecotone production was installed.
Tõnn got also new white ring with code 7X.
As Tõnn is so popular all over Europe, Eagle Club decided to install webcam on his nest this year.
He started his journey home on 22th March 2017 and arrived on the nest 4th April at 15.00.
