The purpose of the survey was to map the distribution of all bird species, generate information on patterns of relative abundance, quantify distribution changes, inform conservation priorities, and engage a new generation of recorders.
Two fieldwork methods were used. As part of the Roving Records, bird record from every 10-km square were collected, which were used to describe the distribution range. The Timed Tetrad Visits (TTVs) method gathered records from tetrads (2 x 2-km squares) and were used to generate information on relative abundance of a species within a 10-km square. The data were used to produce the BTO/SOC/IWC Bird Atlas 2007-11 (Balmer, D., Gillings, S., Caffrey, B., Swann, B., Downie, I. & Fuller, R. Bird Atals 2007-11: The breeding and wintering birds of Britain & Ireland. BTO Books, Thetford).
The survey covered both Britain and Ireland, but only the Republic of Ireland subset of data are displayed.
Four winters and four summers from November 2007 to July 2011.
Hiqh quality. All data underwent rigourous data verification and validation.
Complete, except for records of some of Ireland's rarest birds.Sighting of red-necked phalarope, white-tailed eagle, golden eagle, black-tailed godwit, marsh harrier and little ringed plover during the breeding season, and golden eagle in winter, are not mapped in order to safeguard these species from possible disturbance.
