Andy Musgrove


Associate Director - Monitoring


I oversee the work of our two monitoring teams – Surveys and Demography – which collectively cover almost all of the surveys and schemes where volunteers contribute their records of birds they have observed, counted, ringed or nest-recorded.

Research Interests/Responsibilities

The Surveys and Demography teams organise volunteer-based surveys to collect the data underpinning the BTO's definitive status measures of UK bird populations, including population estimates, trends, distribution, productivity, survival and movements.  We disseminate our findings to researchers, government, consultancies and the wider public.  I am particularly involved in the development of BirdTrack, and more widely interested in development of intuitive and attractive online recording approaches to data collection.  I am also interested in understanding to what extent the UK's volunteer birdwatching network can be mobilised to collect useful data on non-avian taxa.
