Together with the usual midwinter waterfowl count in January 2010 there will also be an international swan count. It is arranged by the Swan Study Group of Wetlands International every five years, to estimate the number of swans and to map their wintering areas.
The previous count was in 2005; then we were estimated to have 4000-4500 mute swans, 600-650 whooper swans and about 10-15 tundra swans wintering here.

This time the time period for the midwinter waterfowl count, and so also for the swan count, is January 9 – 24, but we ask you to have the counting trips as near January 16-17 as possible; these are the central days of the count, and it will help to avoid double counting of birds.

Our aim this year is to have observers to cover all of Estonia’s ice-free coasts and inland water bodies. Since swans are easily determined species, counting them suits even beginner bird friends, and all are welcome to help.

Of course all are also welcome to the counting of other wintering waterfowl. No more is needed than that the other species are recorded too, besides the swans. Material for the count (observation forms, info on counting sectors) are to be found on the Estonian Ornithological Society’s web site, under the project heading "Kesktalvine veelinnuloendus (Midwinter waterfowl count)”. http://www.eoy.ee/projektid/tvl/IWCDec09.pdf.

 
From the observers we need as correctly set down data as possible. The best thing is to write one’s own observations on the midwinter waterfowl count form, but it can also be given  in free form. The following data are obligatory:
-          species (if it is not possible to distinguish between whooper swan and  tundra swan, please note at least that there were „yellow-beaked” swans, or whooper / tundra swans);
-          date; time; precise observation point; number of adult and juvenile birds and the size of family groups (if it is possible, and clear how to distinguish groups);

-          ice situation; name/s of observer/s.

 
Tundra swans.
 
Please send the results of the count by post to Eesti Ornitoloogiaühing, PO Box 227, Tartu 51002 (mark envelope “luigeloendus”), or by e-mail to leho.luigujoe@emu.ee.
More information on the midwinter waterfowl count and the swan count is avaiable from Leho Luigujõe by e-mail or by telephone 507 9713.
