A few weeks ago I reported seeing some 1st year swans on our bit of the canal. Today I discovered where they came from. I had thought they were some of last year's cygnets but not so. This evening as I walked along the canal I met a lady looking for 3 cygnets. It turns out she had rescued a couple of swans several years ago and had them on a pond in her garden. Last year they produced 3 cygnets and earlier this year the male was chasing off these 1 year olds as they were breeding again. The woman decided to release the 3 onto the canal and these are the young ones we saw in April. They were in the company of a 2 year old swan.
They haven't been seen for a couple of weeks but this probably means they have moved up the canal a bit. They were certainly trying their wings when I saw them.
