The Nest Record Scheme
The Nest Record Scheme (NRS) gathers vital information on the breeding success of Britain's birds by asking volunteers to find and follow the progress of individual birds' nests.
In the last 75 years the NRS data has been used in scientific research and conservation work - take a look at some of our key achievements...
David Warden in 1946 - our earliest photographed nest recorder. We now have over 600 volunteers.
Yellowhammer nest records have linked the effects of pesticides showing a massive decline in nest survival rates in 1950s-60s, especially at the egg stage
Nest recorders have helped associate reduced nesting success of bird of prey such as Peregrine with harmful pesticides in the 1950s-1960s
Nest recorders have explained the decline of farmland nesting bird, Lapwing - indicating fewer chicks on upland farmland where cow and sheep rates have risen
Song Thrush numbers are falling - data from the NRS and other BTO schemes have indicated that Song Thrush is unable to bounce back from cold winter losses
We target our recording efforts to those species that have faced rapid declines and need help such as pipits, larks, chats and warblers
Celebrating 75 years
This year we’re celebrating 75 years of the NRS and we’d like to thank our dedicated volunteers who take part in the survey - without them the survey could not succeed.
- NRS participants find and monitor over 30,000 nests every year
- Over 1.35 million nest records from 232 species since 1940
- Over 600 volunteers take part each year
- We monitor how well birds are breeding to increase our knowledge of their basic breeding biology
- The fortunes of nesting birds provide valuable indicators as to the quality of the countryside
- We gather information to help determine the impact of changes in habitat and climate on the productivity of UK birds
Call for new volunteers
We’re looking for volunteers to take part in the NRS. You don’t need to be a bird expert to take part and you can start by monitoring just one nest. Read some of our volunteer stories to hear why they enjoy nest recording.
To monitor some specially protected species, it's necessary to obtain a Schedule 1 permit in addition to registering as a nest recorder.
As with all BTO surveys, the welfare of the birds comes first, and therefore all nest recorders follow the NRS Code of Conduct, a protocol designed to ensure that monitoring a nest does not influence its outcome.
The data collected for NRS are used to produce trends in breeding performance, which help us to identify species that may be declining because of problems at the nesting stage. These trends are are updated every year and published in the BirdTrends report. NRS data also allow us to measure the impacts of pressures such as climate change on bird productivity. Please see the results page for more information.

NRS mentoring launched
This spring sees the launch of the NRS Mentoring Scheme, designed to put new participants in touch with experienced mentors for guidance and training. For more details, see the mentoring web-page.
The BTO would like to thank the network of volunteers who take part in the Nest Record Scheme. Without their hard work and enthusiasm the Trust would not be able to monitor the health of the UK’s breeding birds each year.
