Rob and others, The Tengmalms/Boreal Owls (Aegfun) wer enot heard by Janne but by a couple of other people. One of them is close to the North end of the gulf of Bothnia. The Tengmalm call is by description the same as what I call (somewhat incorrectly the Whip call - I'll try to get it uploaded to www.tarsiger.com later tonite).
As for the three crakes Janne heard (of course on different nights), he mentions that they gave calls similar to normal territorialal calls, so that there was no question about the id. Maybe this answers partailly at least your question about spotted's call type in flight. Regards Harry ------------------------------------------------- Harry J Lehto, Ph.D., Adj.
