Population changes of some bird species in Scottish and Welsh Atlantic Oakwoods between the 1980s and 2003/4 using data from the repeat Woodland Bird Survey

Summary Atlantic Oakwoods support a unique breeding avifaunal community, characterised by redstarts, wood warblers, pied flycatchers and tree pipits. We have used a sample of data from the national Repeat Woodland Bird Survey to examine population changes in these four species within Atlantic Oakwoods over the last two decades. We used data from 29 woods in Argyll in western Scotland surveyed in 1985, and from 27 woods in Gwynedd in northwest Wales surveyed in 1983 and compare them with data from repeat surveys carried out in 2003 and 2004. In this paper, we report the population changes for these species between these two periods and examine whether changes differed between Scottish and Welsh sites.
