Later in the afternoon I noticed the crow chasing Ilmar aggressively from the tree and then Irma in the air. It was a crow, I heard it.

What an amazing amount of bird sounds - I never heard such before, even if I have visited several bird lakes, a magnificent night experience, I recommend with full volume this time of the day!

In North Finland at the Osprey nest we still have light (even if still not the midnight sun): http://kotinetti.suomi.net/saaksi/index.php
