BTO House Martin Appeal
House Martins are thought to have declined by 16% in the UK in the last ten years. Worryingly in England there have been declines of 65% longer term which has led to the House Martin being amber listed as a species of conservation concern.
We want to stop House Martins from slipping on to the red list for Birds of Conservation Concern, reserved for species which have seen declines of more than 50% over a 25 year period. But to do this we need to learn more about them here in the UK.
House Martin Survey
We hope to run a new, specially designed survey, comprising of two parts to gather vital information to help us understand more;
- A national survey in 2015 to gather information on the House Martin population, local distribution and their habitat preferences.
- A nest monitoring study in 2016 to learn about breeding success, timings and location of nests.
How you can help
Your gift will help us to establish population estimates, providing a baseline against which future change can be measured, and understand more about the reasons for the steep decline in England. Could it be that the mud they use to build nests is harder to find due to climate change or drought? Have changes in local land-use affected insect numbers and led to a food shortage or is there a lack of suitable nest sites?
Once we have further information we can use this evidence to inform policy and practice to give House Martins a better chance in the future.
