Ms Oonagh Duggan:

We want to know where those are so the Deputy will have to let us know. There are a range of surveys nationally, especially on the likes of the curlew but also on other species. The breeding bird atlas was conducted and published in 2013, I think. That would have been based on the survey work done by volunteers through citizen science. They were skilled volunteers who knew what they were looking out for and could recognise the signs of breeding activity, for example. That is how it is done. I am sure there was also some population modelling included.
