Submitting records to the BTO

Ringing and nest recording data are either submitted to the BTO via Demography Online (DemOn), the online data entry system for ringers and nest recorders to input their data directly into the BTO database. Users are able to input, view and edit their data as well as export information for analyses and report production.

More information on DemOn, including links to introductory emails.

Ringers and nest recorders who have not started using DemOn yet submit records via a free desktop application called Integrated Population Monitoring Recorder (IPMR).

More information on IPMR, including download links for the application and instructions.
