Providing an annual overview of the status of the UK’s breeding and non-breeding bird species in the UK, this year’s report highlights the continuing poor fortunes of the UK’s woodland birds, and the huge efforts of BTO volunteers collecting data.

Audit of local studies of breeding Curlew and other waders in Britain and Ireland

The Eurasian Curlew is widely considered to be one of the highest bird conservation priorities in the UK and Ireland. A number of other breeding waders have also showed marked declines during a similar time frame, and a multitude of field initiatives across Britain and Ireland have been established, or tailored, to support conservation of these wader species. This audit aimed to collate information from as many of these breeding wader projects as possible, to allow BTO to assess how best it might assist local to national initiatives through partnership working in future.

Breeding Peregrines on the up thanks to growth of lowland populations

The return of breeding Peregrines to former haunts, and the colonisation of urban sites such as industrial buildings and cathedrals, has not gone unnoticed by birdwatchers. It is only now, however, with the publication of the results from the latest national Peregrine survey, that we can put figures on the changing fortunes of this stunning bird of prey.
