Wader population trends on the UK's open coast
Newly published research from BTO underlines the importance of the UK’s rocky shores and sandy beaches for waterbird species.

Living fast: using ringing data to look at survival of British Peregrines
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.
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.
Pheasants and Red-legged Partridges for commercial shoots may be boosting numbers of the avian predators and scavengers.

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.
