Standing on the line

The swans are here, at last. Many marks indicate that Spring has come earlier than last year. But not the swans to lake Tuusulanjärvi.
Beautiful sunny morning. I was driving to work when I saw two swans flying to lake. I turned back, went to a only place free from ice and there they were.

I think these four are just passing by. There are a couple nesting, perhaps the two flying were those. I hope so.
