I saw swans on the canal this morning (as I always do) and what a beautiful site. But this morning a couple of them were thrashing the water with their wings (swans still floating in water and wings still folded, just slightly open). They thrashed really hard. Then they almost stood up in the water, spread out their wings (like a crucifix) and floated along like that. I'm wondering why they did this. The obvious answer is that they were washing and then drying their wings, but is that right? They are fabulous creatures.
