Irish Wetland Bird Survey

Monitoring wintering waterbirds in Ireland

 

International Swan Census 2020

11th/12th January 2020

Each winter over 400 skilled volunteers, NPWS Rangers and BirdWatch Ireland staff monitor wintering waterbird populations at their wetland sites across the Republic of Ireland. The Irish Wetland Bird Survey (I-WeBS) is coordinated by BirdWatch Ireland and funded by the National Parks and Wildlife Service.

What’s involved?

I-WeBS counters record waterbirds at wetland sites across the country during the winter ‘non-breeding’ season (September to March). The type of wetlands surveyed range from wet grasslands to large complex estuaries that hold thousands of birds, and everything in between. We’re always in need of new counters, so if you have a telescope and would like to get involved to help monitor your local waterbirds, see ‘Get involved in I-WeBS’ below.

Why do we count waterbirds?

Hundreds of thousands of migratory waterbirds spend the winter in Ireland, relying on our wetlands to feed and rest. Most of these birds spend the summer nesting in arctic regions (e.g. Greenland, Iceland, Scandinavia, Siberia) but fly south in the autumn as their breeding grounds freeze over. As Irish wetlands are so important for their survival, these wild birds and the habitats they rely on are protected by national and EU legislation. And so, I-WeBS exists to keep track of how these birds are faring. With this knowledge, informed conservation action can be taken.
