Song thrush  (Turdus philomelos)

After the mid-1970s there was a steady decline in song thrush numbers; since then a decline of 73% has occurred in farmland and 49% in woodland habitats (3). Although the reasons for this decline are not yet understood, it is thought that the widespread changes in agricultural practices have been involved; removal of hedgerows has caused a loss of nesting sites, and the increased use of pesticides and the loss of winter stubbles have reduced the food supply. Predation by crows and foxes and competition with blackbirds may also be important (3).

The severity of the song thrush decline was recognised fairly recently, so very little conservation work has focused on this species to date. The RSPB is promoting environmentally sensitive farming practices as a means to conserve the song thrush and other threatened farmland birds. Research into the ecology of this species and the causes of the decline is ongoing. Gardens are important habitats for this species; certain measures can be taken to make a garden more attractive to wildlife (2). The song thrush is a priority species under the UK Biodiversity Action Plan (UK BAP), and a Species Action Plan has been produced to coordinate its conservation (3).
