There are new birds on migration map. As Buzzard year is ongoing in Estonia, we start with those. Additionally to known Villu we can follow another Common Buzzard named as Kordian. He was caught about 20km westward of Villus territory. Kordian is born this season and flew around nearly three months before trapping. We don't know where exactly he hatched, but probably not very far of trapping place. Name Kordian is dedicated to our Polish colleague Kordian Bartoszuk from AQUILA-IT company, who replaced the old data logger used last year to new one. Where Kordian winters, that we can see in coming months, if everything goes well.
Second male Osprey we added to follow it, he is named as Markus. That is dedicated to our helper during the field works and during trapping of Ospreys, the guy form Austria, but living in Munich. Osprey Markus breeds in northern Estonia, Lahemaa National Park. There was two chicks in nest and mate wearing the Finnish ring. Today we have no ringing data, yet. If Osprey Kalle is stopping over in Ukraine Black Sea coast, then Markus stops also in Ukraine on Dnestir river, in Podilski Tovtry National Park.
The Lesser Spotted Eagles (LSE) are on migration in the same numbers and individuals as last year. Last started Jaan, Max and Mait at noon 26th of September.
Additionally to Common Buzzards the migration have not started two Greater Spotted Eagles (GSE), but it will take probably not long time to see them on a way south.
White Storks of Slovenian colleagues are both in Chad wintering, but the GSM network is there weak to get data regularly.
18.09.2015 Black Stork Eedi and others
The Black Stork named Eedi got logger in 1st of September in southern Estonia, Karula National Park and started autumn migration in 9th of September. By now Eedi is in Ukraine or even further - we get saved information of transmitter after every five days. At least this year Eedi is quite late migrant, but it could be caused by late breeding. The trapping images of Eedi are in his gallery.
LSE Haage stops over also in Ukraine, probably waits for other LSEs to migrate together ahead. Other LSEs still in breeding sites, but soon they leave. According the information from German colleagues there also first LSEs started. We can see some movement with hybrid spotted eagle Tunne who will go to the third autumn migration. This morning Tunne woke up in Lithuania, near Utena.
The Cranes both started migration together, but in Latvia appeared in different flocks. So Savimäe stays in Latvia and Ahja4 flew further to Belorussia.
09.09.2015 First LSE started to migrate
Female Lesser Spotted Eagle (LSE) named Haage started the autumn migration in morning 8th of September. She did not have chicks to rear this season. During first day she covered at least 250 km - direct distance between breeding site in Estonia and overnight place in southern Latvia. Successfully bred LSEs still train the juveniles for independent life.
07.09.2015 Autumn migration 2015
This season the migrants were quicker as data processor. With help of Slovenian colleagues there is new species on migration map, the White Stork, which migration we can follow since 10th of August. Both juvenile storks Fortuna and Zuri flew in one flock up to Bulgaria, but later in different groups up to Chad. The Slovenian Black Stork did not send any information since winter in Nigeria.
There are two male Ospreys tagged in Estonia during the summer 2015, and logger of female Tiiu removed same time. One of those males Kalle is a mate of Tiiu and he started to migrate recently in a morning of 4th of September. They were quite early breeders. Second male Osprey will be added to the map if starts to migrate.
We can follow already tenth autumn migration of Black Stork Raivo, but he arrived to wintering area in 28th of August after 11 days of migration. That is second quickest migration during those years, in 2013 he covered that in 9 days, but in some years it takes a month. We tagged also second adult Black Stork, but we wait for migration data there. That stork trapping was really difficult and therefore so late start of migration map occur. Also we were happy to remove not functional transmitter form another Black Stork Valdur, tagged in 2008.
The Common Cranes Ahja 4 and Savimäe are in the same area, probably also in the same flock and feed themselves before migration.
White-tailed Eagles Meelis and A531 did not breed this year. The age of Meelis did not allow breeding, yet, but A531 still searches for nest site and hopefully founds a mate since next season.
Common Buzzard Villu bred successfully and reared one chick. Lesser Spotted Eagles and breeding Greater Spotted Eagles we add to the map if they start migration.
18.05.2015 Migrants arrived and nest
In general, we do not show the breeding time movements of the tagged birds, but for bird of the year, the Common Buzzard, we made an exception - it is possible to follow Buzzard Villu, only the locations just near the nest are not visible. There is an overview about first month of Villu on breeding grounds available in website of bird of the year (in Estonian). The results of breeding of Villu we will see nearly in one month, as he seems to be later in breeding than our webcam Buzzards in first or in second nest.
All Spotted Eagles (both, LSEs and GSEs) reached their breeding grounds and the last one was LSE Jaan, who arrived in 5th of May. Usually in that time first eggs are laid... Hybrid spotted eagle Tunne stops in Russia, Pskov oblast, but we will see if he stays there or moves more northwards. Anyway, Tunnes migration route this year is unusual. Breeding results will be available in July after the nest controls.
Osprey Tiiu, whose migration we followed in last autumn, is incubating on her nest, but logger is not working. When the chicks will be big enough we try to remove that useless transmitter from the bird.
Followed Cranes are both in Estonia, but they do not breed, yet.
04.04.2015 Black Stork Raivo arrived
Black Stork Raivo reached his breeding grounds in last day of March and as usual, checked first the nest. Nest is not shown in map. It is known that black storks have been observed during last days also in other places in Estonia. The pair is in Latvian camera nest.
Common Buzzard Villu is in his breeding territory, that is the same area we caught him in autumn.
Lesser Spotted Eagles (LSE) stuck in central Africa appeared to be nothing special for our tracked individuals, but the same problem with LSEs tracked by German colleagues. Only LSE Aadu is well in average migration schedule and Max is close to that, but other individuals are far behind. Most probably that is caused by unusual weather conditions, but could be linked also to feeding conditions during the wintering. In average LSEs arrive to Estonia around 10th of April.
The hybrid Spotted Eagle Tunne has chosen surprising migration way. His last locations come from Armenia, about 2000 m.a.s.l., so Tunne probably wants to cross Caucasus Mountains. And where further...? No one our tracked Spotted Eagle, either LSE or GSE used that migration path before. Second hybrid Spotted Eagle Sander is well competing with Aadu.
Common Cranes are slightly further as their migration route shows, there is no exact locations available, yet. So Savim?eis in Hungary andAhja4 stopped for shortin Crimea Peninsula and then in Ukraine.
GSE T?nn was in March well in his wintering areas, there are new images of him in the T?nns gallery. Trapping of T?nn did not be successful this season, we need to try once more.
Unfortunately, there is nothing known about Osprey Tiiu and Black Stork Francek.
23.03.2015 Buzzard Villu seems to arrive first
Estonian Ornithological Society follows one individual of the bird of the year - Buzzard, who was named as a result of the referendum - Villu. Spring migration of Villu began after wintering in southern Germany, near Munich on 8 March. The first week was spent like for to warm up, distances per day were modest and long stops occur between those. So Villu moved cross the Czech Republic to Poland. Next the migration speed increased and Villu flew some times more than 200km per day. By afternoon 22 March was Villu reached the middle of Lithuania. If the same tempo is going on, then he will soon be in Estonia probably. Villu
bears transmitter ofECOTONE SULA type weighing 28g. This device determines
the location of the bird, four times a day, and sends the data if four locations are collected. As
sometimes there is not quickly possible to take the location of a GPS device, it will
shift in the transmission of data (compared to the previous
day). We try upload new information received from the transmitter as soon as possible to public migration map. Villu migration destination... we still do not know it. But nearly at noon 23rd of March Villu crossed border between Latvia and Estonia.
Lesser Spotted Eagles (LSE) behaving slightly weird in region of Uganda, they do not want to fly ahead over there. For
example, on March 13, Magnus turned around near nothern border of Uganda and flew 1200km
south. Only on March 19 he decided to re-take the north. A
similar behavior has been reported in the case of migratory birds relatively rare in the past, but the reason is unclear. Generally, the spring migration of the LSE are less synchronized than the autumn migration. In the spring the migration of various individuals is different according the start and progression. Also arrival to breeding sites will be therefore uneven.

05.03.2015 Spring migration started
The spring brings some new species onto migration map, but some we have lost (temporarly).
As a newcomer on map the bird of the year 2015, the Common Buzzard. A tracked Buzzard is at the moment in south-east Germany, yet. That particular bird differs of others, he has no name. You could repair that, sending a name through special form. Dead line is at 15the of March.
There are lost form map the Black Stork Francek and Osprey Tiiu. Probably they are out of GSM network.
Quite a similar time started veteran Black Stork Raivo and male Lesser Spotted Eagles. The females are not hurry, Karin on place in Angola and Haage in Southern Africa.
11.01.2015 Positions in new year
Most of transmitters work during winter in saving mode. Only few locations of birds are taken in day and accordingly the data transmissions happen not often. Transmitters using Argos system, send data after every 5-14 days, depends how the program is installed during the production. GSM based loggers transmit every day, but only in case if they are situated in GSM network. Missing network means no data, till bird moves to the network area. Up to end of autumn period on map there is about one month left, from mid February we start with spring season.
Lesser Spotted Eagles (LSE) manage on large territory in the central part of southern Africa. Mainly they use Zimbabwe and Botswana, but Magnus is at the momnet in Namibia, Jaan and Haage in Mosambique. As LSEs fly a lot around, they appear time after time into GSM network and we can follow them virtually.
Greater Spotted Eagle (GSE) Iti has been quite slow this season, she reached Turkey, but seems not hurry. GSETõnn we can't see on map, but he winters in familiar place - El Hondo wetlands, Spain. That is good if we can follow Tõnn also without working transmitter. Sander and Tunne are only half GSEs (hybrids of GSE and LSE), they winter quite close on border area between Sudan and South-Sudan.
Black Stork Raivo is traditionally on fish ponds in Israel, but Slovenian Francek went out of network in November, if reached Nigeria.
Osprey Tiiu is lost time after time, but still fishes at Camoe river, Ivory Coast. Quite in the same place stopped also one juvenile Osprey from Cumbria, Great Britain in autumn 2013.
Common Cranes Ahja4 and Savimäe behave completely differently. Ahja4 uses exactly the same wintering area as last year, but Savimäe migrate in the beginning of the year from Hungary to northern Africa and still moves to the west. Last year Savimäe wintered in Hungary and after short visit to Latvia in spring also spent summer in Hungary.
Fresh data about White-tailed Eagles are missing as batteries of their loggers are empty.
17.11.2014 Wintering sites choosen
The winter in our birds nest sites is not started, but almost the followed birds are well settled on wintering grounds. Only Greater Spotted Eagle Iti still migrates and we can't say now about Crane Savimäe, yet.
By the species the wintering site term is different, in general there are two strategies of wintering among migratory birds. Osprey, Greater Spotted Eagle, Black Stork, partly also Common Crane use for wintering certain, relatively small area, what those individuals have selected in the first years of their life and they fly every autumn exactly to the same place. If the local conditions turn unfavorable (e.g. water body dries out), the spare places are used and those places are also used year after year.
Different strategy is used by Lesser Spotted Eagles (LSE). They migrate to the furthest wintering area among our birds and move around during the winter in a wide scale. The core area of wintering of LSE is about 1000x1000 km and there are wintering about 100 000 individuals of LSEs (mainly from Europe). In good days there is possible to see tens of LSEs from one observation point. Hence, in that vast area, there are very few birders who can forward that kind of information. Our information is based mainly on Dr Bernd Meyburg information.
