Summary of autumn migration

Printer-friendly version

We started autumn migration on migration map with 23 birds presented and of those 7 were juveniles. Biggest is the juveniles percentage among Cranes. At the same time we know well, that due the natural selection big proportion of juveniles do not reach wintering grounds. So we can see on wintering grounds only two Cranes, Ahja2 and Juula2. Both of them winter in Tunisia, though Ahja2 spent last winter in Turkey. Changes of wintering areas are possible to see also among Finnish Cranes.

Migration map is available here.

One of five Ospreys, Ilze form Latvia, got perished in Calabria, southern Italy. Probably she was shot, injured and of that Ilze did not recover. Unfortunately the transmitter was not found, though two times our Italian colleagues tried to. Second Latvian Osprey, Eriks, we lost in Gabon in October. We hope he is out of network area and will be visible if starts spring migration. Estonian Ospreys winter in Africa, Ilmar in SW Angola, Piret and Erika in Sudan. Piret was also out of network area for 40 days, if she went 200km northwards to winter. With Piret there was interesting about 1200km long back migration from Sahara, border area between Egypt and Sudan. She turned suddenly back in morning of  9th of September. At the moment there is no data what happened with weather there, but something induced so long extra trip. Back way to Nile Delta seemed to be not easy because of dominant north winds.

The Black Storks winter in the same places as they did usually, Raivo near fish ponds in Jordan Valley, Priidu in Sudan and Central African Republic, Pirsu in Chad and Cameroon.

The juvenile White-tailed Eagles Sillu and Meelis did not migrate much (probably), but the transmitters on them are not well working at least in winter  time , and we don’t know about their last movements. Last positions we know from November about Sillu in Kaliningrad region, Russia and about Meelis at Russian coast of Pskov Lake. But the batteries are empty and in spring we hope to see the birds again moving.

Among Greater Spotted Eagles probably the most interesting is juvenile Tore, we expect to be brother of Tõnn. We lost him in Switzerland, being long time observed near Lake Constance by local bird watchers. As the bird seemed behave well, we suppose the problems with transmitter, maybe shortage of sun light. Tõnn and Iti are wintering in usual sites. Sander is known first GSE from Estonia and wintering in Africa. The wintering site of Osprey Piret is situated only some 200 km SE of Sander.

Lesser Spotted Eagles Karin and Magnus migrated typically to the species and made it up to southern Africa. The wintering area is large, including several countries (Zambia, Zimbabwe, Botswana, Namibia, South-African Republic). The hybrid Spotted Eagle Luule fall in marine troubles in December trying to cross Ionian Sea form Greece to Sicily and most probably drowned.
