01.06.2016 Birds are breeding, but results will be known later
Birds we can follow, started to breed and results will be along we check those nests. Different species will be checked in different time, depending on development of chicks. At the moment is White-tailed Eagles survey ongoing, but will be followed near the end of June by Black Storks, afterwards Ospreys and then Lesser and Greater Spotted Eagles in July.
There are nesting White-tailed Eagles A531 (in Latvia), Pomo and Kirilla (in Russia), also both Black Storks, Greater Spotted Eagles and Ospreys. Of LSEs there are more connected to nest sites Karin, Magnus, Jaan, Vahur and Mait. Other LSEs might be stopped nesting (here is probably not good food year for LSEs).
There are also immature birds not nesting, yet. Those are Crane Savimäe, Black Vulture Mikho, White Stork Fortuna, White-tailed Eagle Meelis and Common Buzzard Kordian. Movements of these birds we upload to the migration map according the data received.
We do not have new data of White Stork Zuri, hybrid Spotted Eagle Tunne and crane Ahja 4. Of those we know perishment of Ahja 4. With others it could be problem with transmitter, hopefully.
05.04.2016 Black Storks arrived to breeding sites
Like in last years we observed, among first arrived Black Stork Raivo. He reached nest site in evening 29th of March and probably restores the nest now. Soon, in 1st of April crossed Estonian border second Black Stork named Eedi. Eedi did not fly directly to nest site, but more westward and after a day directed to Karula National Park, we suspect him to breed. He did not stay in Karula, but returned to Latvia for 80 km.
First among Lesser Spotted Eagles ( and all spotted eagles) is Aadu, he could reach nest site in two days. The row of Lesser Spotted Eagles dragged for long, finished with females Karin and Haage. Last birds still in Africa.
Osprey Kalle wintered in no network area, but started migration in morning 22nd of March from the lower Congo river and will be soon over Mediterranean sea. Into network he appeared only in Algeria and sent then all previous locations. OspreyMarkus started much earlier, in 9th of March, but disappeared from network by evening same day. We don't know if everything is fine with this bird.
Common Crane of fourth calendar year Ahja 4 perished in Sudan, New Halfa region. It is known that the cranes are hunted in this region on crop fields and probably Ahja 4 is shot. In Sudan we have good collaborator Moez, who tries to find transmitter there. Moez helped us also previously to find perished birds and their transmitters in Sudan. With other craneSavimäe it seems everything good, but he is not breeding probably, yet.
White-tailed Eagle (WtE) Pomo data are not updated anymore, because she started to visit possible nest site. Probably she did not lay eggs this season, what could be caused by lead poisoning this bird suffered. Another WtE Kirilla flew far NE (more as 1200 km) and since 1st of April is out of network.
Common Buzzard Villu arrived to the breeding site, but his transmitter is not working. Logger of Kordian awoke in the end of March, he is almost in same area in mid Poland, as at the turn of the year when Kordian disappeared.
17.03.2016 Spring migration is progressing, South Africa empties
Spring is developing in Estonia and also in migration routes of our birds. Usual earlier migrants, like Black Storks are in southern Europe and there is not so much to fly to breeding sites for them. So Black Stork Raivo stopped in Bulgaria and just started to fly ahead. Eedi only arrived to stopover place, but we will see for how long. Common Cranes probably were awaited to start earlier, because both could start to breed this year, but they know better.
Lesser Spotted Eagles (LSE) left by now southern Africa and hurry to breeding sites. Females are clearly lagging behind. Aadu and Max, the neighbors in breeding sites compete for first position, as in previous years. Hybrid Spotted Eagle Sander has flown few thousand kilometers less, so he has advantage. Greater Spotted Eagle (GSE) Iti started quite early this year, but most likely she will make a stop over in Bulgaria. Hybrid Tunne gave us last data in February and after that it is silence. The reason is not known. Broadcast of Osprey Kalle stopped in early February, Osprey Markus started spring migration, but during a week there is also no data available. White-tailed Eagle (WtE) Pomo is probably not breeding, yet and Kirilla flies northwards along Kama river in Russia. Also there is no logger data of Buzzards since late autumn.
01.03.2016 Spring migration 2016 started
It is not easy to say, when exactly started the spring migration. Among typical migratory birds first stared Black Stork Raivo. We can follow him already ten years. Worn transmitter of Raivo woke up of hibernation in 13th of February and in 17th we can notice Raivo starting the migration form Beit Shean Valley of Jordan river. Since today Raivo has covered about 1800 km and stops in central Bulgaria, known place for Raivo.
Also White-tailed Eagle (WtE) Kirilla moves northwards, but she started alraedy in 4th of February and does not hurry much. We will see where Kirilla goes. WtE Pomo stops in Baltic sea shore in Kurgolvo peninsula. If she starts to nest, we stop public following of Pomo - like with all stricktly protected species. In general WtEs are not listed as migratory species.
Lesser Spotted Eagles (LSE) also move northwards, but it is still difficult to say if that is really migration. Though males seem to be more interested in spring duties. LSEs have to fly longest distances of our birds we can follow here.
Not all birds are on map, because not all of them sent data since mid February, when we turned page in migration map. But in general during the migration there will be more often new data available and relevantly migration map will be updated.
14.02.2016 Autumn season terminates
In the mid of February the autumn season on current migration map will end and we start with spring migration season. Therefore on default map, there may not occur all birds at once, but according the data we receive. Part of birds send us data after every ten days only. But there are some news for to complete autumn season.
Two White-tailed Eagles (WtE) are new birds on map, both most probably females - Kirilla and Pomo. The following of Kirilla is possible since end of January and since 4th of February she started moving north-east direction. Her nest site is not known, neither age and origin. Wintering area is situated eastward of Volga river on border of Uljanovsk and Samara regions. WtE with preliminary name Pomo appeared with lead poisoning in vet clinicum of Life Sciences University of Estonia and was seriously treated during nearly a month. After recover the eagle was released in 12th of February on shore of Peipsi lake. Surprisingly eagle directed eastward and flew quickly to the peninsula Kurgolovo in Russian shore of Baltic sea. It is possible that this eagle breeds in that place, because according our colleagues in Russia the area is suitable for WtE and eagles have been observed there as usual.
Pleasant surprise was caused by German colleagues who send photos and observations of Common Buzzard Villu. We lost communication with Villu in northern part of Czech Republic in 11th of December. Villu was found wintering exactly in the same field as last year. By descriptions Villu feels there like at home, photos are uploaded into Villus gallery. We need to think about removing the malfunctioning logger if Villu returns.
Unlike the past Crane Ahja4 does not winter in Sululta plains near Ethiopian capital, but returned northwards to the Tana lake, where stopover site of Ahja4 is known. The reason is drought in Ethiopia, what led the entire region close to humanitarian crisis. In usual wintering area Ahja4 did not find safe water bodies for overnight anymore and had to find other place, easiest probably was to fly in to known place.
The Lesser Spotted Eagles (LSE) used for moving on wintering area almost the same patterns as previous years, adult birds have own tracks they use during the winter, e.g. Jaan used to fly eastward (Mozambique) before spring migration, but Max northward, to have better start position to migrate into Estonia.
14.12.2015 Not all reached wintering grounds, yet
The most distant migrants, Lesser Spotted Eagles (LSE) fly around in a hudge wintering ground, but some much closer migrants did not hurry. Probably both Common Buzzards are still on a way, but we don't know about Kordian that exactly, yet. Kordian could winter in mid Poland. And the Cranes will continue the migration most probably.
There is new species on map - Black (or Cinereous) Vulture named as Mikho. Mikho got the tag in Georgia and moved up to now into border area between Iran and Pakistan. We don't know if this is his wintering place or flies he further.
Black Stork Eedi is wintering in Saudi Arabian SW corner and spends most time on a wadi, where probably some water and food inside. Raivos transmitter is ten years old. We did not get signals since end of November, but probably the feathers of black bird cover the solar panels there. Same story with White-tailed Eagles.
Osprey Kalle has been disappeared more as for one months, but now he has moved and sends the data from past situated on lower Congo river basin. This area is not good for GSM network as also other Osprey, Markus has been lost during last ten days.
Greater Spotted Eagle Tõnn, whos transmitter is not working is wintering again in El Hondo wetlands, Spain.
Part of transmitters are working on winter schedule to save energy in poor light conditions. Also not all birds are in GSM network all time. Therefore data update could be irregular on map.
14.10.2015 All birds migrate or are wintering
All the migratory birds we can follow, are migrating or wintering. Last who left breeding grounds was Common Buzzard Villu. He started in 11th of October. Immature Buzzard Kordian has got some advantage in distance, but they are not much hurry. Weather is good and there is no reason to rush.
Black Stork Eedi choose in Near East a bit different fly way as usually Black Storks do. Eedi follows Red Sea coast on Arabian peninsula. Among our birds the same path has been used before only by juvenile Black Stork Priidupoeg in 2008, but he did not finish it. Current season there is also Black Stork of Latvian colleagues of second calendar year named Kate, who uses similar migration path. It is very interesting to see how they manage and where stay for winter.
Common Crane Savimäe stops like last year in Hungary, but last year he was there for almost summer. Ahja4 stops over in northern Belorussia, but moves more around as during two previous years. Probably in ten days will be clear if he flies to Ethiopia again.
Immature White-tailed Eagle Meelis flew about 200 km westward from Russia to Estonain-Latvian border area near Baltic sea. Similarly behaved he also last year, but now we have more data as weather is more sunny and charges better the battery in transmitter.
08.10.2015 Common Buzzards started migration
Nearly all migratory birds on migration map are away from Estonia, some already in wintering sites. Common Buzzards leave last among our followed migratory birds. Of two Buzzards we can track, the youngest named as Kordian started first. In 5th of October he left familiar fields and woods in Polvamaa county and flew to south. After crossing Latvian border he justified direction a bit westward and reached Lithuania by second day of migration. There he made some stop, probably for to get personal meeting with some local rodents... Second tagged Buzzard we already know and would be surprise if he stays here in Estonia for winter. Last autumn Villu started in 4th of October, so wise is to hold eye on.
White-tailed Eagles are not typical migratory birds, but can make the surprise with long flights. Probably there will be more local the Latvian old eagle A531, but our Meelis flies more around..
Both of Ospreys left their stop over sites in Ukraine and cross the Sahara now. Destination place they know only by themselves, we can see those a bit later.
Lesser Spotted Eagles (LSE) reach just now the near East countries. First is there LSE Haage and there was counted last season over 124 000 LSEs (data of colleague Thomas Krumenacker). Our two hybrid spotted eagles among others.
27.09.2015 Migration news
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.
