The climate around Spiez was not too hot yet not on the freezing side either, making it a great resting and living area for swans.
I could only imagine that the lake was full of small critters and plants for swans to feast on. During the colder winter months, I wouldn’t be surprised to see a lack of any life on this lake as swans would migrate to a warmer area. The intelligence and bond between swans is also an amazing feat as they often stay paired for life.
