House Martin Nest Study 2016-2017
Thank you to everyone who took part in the survey in 2016 or 2017 - we collected data from over 9,000 nests in total across the two years of the survey.
What did the survey involve?
Survey participants were asked to carry out an initial visit to record some simple information about the site and any existing nests. After this initial visit, they observed the nests for just a few minutes approximately once a week to record any activity seen. Detailed survey instructions can be viewed on the Resources page for the Nest Study.
