2025 Mute Swan RAS (Census)

 Mute Swan RAS

Each year I do a Re-trapping Adults for Survival (RAS) project on the Swans of Dublin, East Kildare and North Wicklow.  The project boundaries are the same as the Richard Collins extensive research in the 1980's.  Instread of re catching Swans to identify them, they are fitted with coloured rings so they are all easily identified at a distance.

As part of the project nesting and cygnet numbers (Productivity) is recorded.  2024 was a really poor year, hopefully 2025 will be better.
