This national survey is ongoing.

This is a UK-wide survey organised by the BTO for the winter of 2025/26. The time period for the first visit finished at the end of October but data from the later visits are still welcome. Ideally there are three further visits, one each in December, January and February with at least four weeks between visits. The surveys are based on the randomly selected Breeding Bird Survey squares. Surveyors should be able to identify by sight and sound the species that might be expected within the county in the winter. If you would like to contribute please contact Martin Ketcher martinketcher@gmail.com or the BTO at https://www.bto.org/get-involved/volunteer/projects/winter-bird-survey.
