Climate change and renewable energy
Climate change may have significant impacts on waterbird and seabird populations (Maclean & Rehfisch 2008, Maclean et al. 2008a, 2008b, Frederiksen et al. 2007). BTO work has documented how the wintering distributions of waders, such as Curlew, Grey Plover, Dunlin and Black-tailed Godwit, in the UK and north-west Europe have recently shifted in easterly, northerly or north-easterly directions as mean winter temperatures have increased (Austin & Rehfisch 2005, Maclean et al. 2008c).

Renewable energy such as wind, wave or tidal power is one way to reduce the amount of CO2 we produce and thus minimise the effects of climate change. However, many renewable energy technologies could potentially impact waterbird and seabird populations. BTO work to address these issues includes:
• Assessments of the potential impacts of tidal power schemes on estuarine waterbirds and other biodiversity, including leading on the waterbirds and biodiversity studies for the recent Severn Tidal Power Strategic Environmental Assessment (Burton et al. 2010, Wright & Clark 2010, Wright et al. 2010);
• Reviewing and providing guidance on survey and analytical methodologies used in Environmental Impact Assessments for offshore wind farm developments (Chamberlain et al. 2006, Maclean et al. 2006, 2007a, 2007b, 2008d, King et al. 2009, Thaxter & Burton 2009);
• Research using tagging technology and modelling to investigate the interactions of seabirds with existing and proposed offshore wind farm developments;
• Running a Secretariat to provide Strategic Ornithological Support Services to the offshore wind industry, identifying and conducting key pieces of research to improve our understanding of how birds might be affected by offshore wind farms.

Migration blog – Winter
As we get ever closer to the end of autumn the pace of migration steadily slows, and as the daylight hours shorten so does the variety of birds on the move.
