The new pair of swans on the Wells Bishop's Palace moat are now incubating 4 eggs on their nest. They only arrived at the beginning of May https://365project.org/julienne1/365/2019-05-10 but have obviously decided that this is a suitable home to bring up cygnets. I have to say it's a beautiful spot to raise a family. They are even being monitored on a webcam https://bishopspalace.org.uk/attractions/swans/
