A survey of bird distribution, in summer and winter, over the four year period between 2007 and 2011.Purpose
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.
Sampling Description
Quality Control
Hiqh quality. All data underwent rigourous data verification and validation.Method steps
- 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).
