Swan concern

   Hello all,

I have grown concerned about what I think is a maturing cygnet. Though I think this may be normal behaviour over territory, the male is becoming increasingly aggresive, and the ?cygnet hasn’t been in the water for over a week, looking to be becoming more weak as time passes. I’m not sure if it’s maybe dehydration or more tame as it’s maybe a female? It won’t leave and has been near the same spot for around a week. Can anyone advise? Is there reason to report this bird as a cause for concern? Will attach some pictures, one of the bevy in June 2023 last year and the ?cygnet in the water on 20th May this year and then a picture from today. Any advice would be greatly appreciated
