WPC: Juxtaposition

I posted a clipping of this pic on former post already. Today I am showing it in all.

It is a group of wooden statues placed in a convexity of a rock face on a promenade near Sierre. I still couldn’t find out the artist or – the question that bothers me most – why she or he placed those white bird figures between them. Maybe there was a juxtaposition intended…
