This local survey is complete.
The 2022 Mute Swan Breeding Survey has now finished, with records of breeding activity received from 44 sites - these can be found on the interactive map here which also includes locations of 5 further sites just outside the county boundary. This count is down compared with the previous survey in 2002 which produced 62 breeding pairs.
A number of the nesting sites do not have a known outcome - if you are aware of cygnets hatching and how many survived, or indeed of any nests not on the map, please contact Graham Knight with details here
Colour-ring sightings: Many Mute Swans in Hertfordshire are colour-ringed, and we continue to welcome any details of ring numbers with your observations. Whether breeding or not, colour-ring sightings should also be sent to Mike Reed, who will also provide a full history of the bird on request – contact details here
Injured or distressed Mute Swans: any birds that are injured or in any sort of distress should be reported to Swan Rescue Hertfordshire – contact details here
