Cranes preparing for the night

In September before the big migration cranes get together for every night on a big swamp in Isosuo-Puurijärvi National Park. They come in smaller or bigger groups. After some hours they start to fly into Puurijärvi bird lake to spend the night. The first cranes again in small groups and then the others in accelerating tempo and size the whole happening climaxing when the sun goes down. That is really fantastic sight.
