Data entry, survey maps & recording forms

In order to help us understand where your sightings or where breeding activity occurred it is really important that you submit your records. Please submit all records by the 31st August 2022 to allow us the time to input and analyse the data.

All submitted records will be compiled and stored securely by the project team, recognising the sensitive nature of some breeding locations. Without the exact locations of territories or nest sites (6-figure grid references) we will not be able to produce comprehensive and precise estimates of population size or distribution. Site-location information will be kept under lock and key for hard-copy form and/or in password-protected electronic form.

If you use printed maps and forms in during your field surveys these forms and maps can be submitted by:

  1. Hard-copy data can be returned by post to one of the below addresses:
        Dr Marc Ruddock (GET): 12 Ely Place, Dublin 2, Co. Dublin marcruddock@goldeneagle.ie
