Head of Ringing & Nest Recording Team
Dave is responsible for managing the Nest Record Scheme, the Barn Owl Monitoring Programme, and the Constant Effort Scheme and Retrapping Adults for Survival ringing projects.
Interests & Responsibilities
- Responsible for overseeing the four BTO volunteer demographic monitoring schemes: Nest Record Scheme (NRS), Barn Owl Monitoring Programme (BOMP), Constant Effort Site (CES) ringing scheme and the Retrapping Adults for Survival (RAS) ringing scheme.
- NRS and BOMP focus on the collection of productivity data at the level of the individual breeding attempt, while RAS collects survival data on species poorly covered by more general ringing. CES collects information on survival and per-season productivity. All these schemes feed demographic data into the BTO’s Integrated Population Monitoring programme.
- Involved in development of novel monitoring schemes to collect avian productivity data, e.g. Nesting Neighbours.
- Responsible for managing the Nest Records Organiser and the CES/RAS Organiser.
- Involved in analysis of avian productivity data and author on over 30 refereed scientific papers, reports and reviews. Specific research interests include the effect of weather and climate change on breeding success and the role of nest predation in determining reproductive success.
- Nest recorder, with experience of monitoring large nest box populations and finding nests of open-nesting species, and licensed bid ringer, currently holding a C Permit
