2025 Mute Swan productivity

02/06/2025 14:15 Swan Nesting Census 2025

The Swan nesting census is nearly finished for 2025.  My boundaries are the greater Dublin area which includes East Kildare and North Wicklow.   2024 was very poor and below what is needed to maintain the population.  We only had 116 cygnets hatch and many of them did not survive the first 12 weeks.

The following is the outstanding nests / data .

Baldoyle Estuary. New nest site.  Still nesting.  Neither Swan identified.
