Denmark lost nearly 3 million farmland birds in the last 4 decades

Nearly three million birds have disappeared from Denmark's farmlands in the space of four decades, according to a report. 15 of 22 species of bird connected to farmland habitats have shrunk in population size, while seven species have increased, reports the Fugle & Nature (Birds and Nature) magazine. Counts by the Danish Ornithological Society (DOF) over the last 40 years have shown significant reductions - in some cases well over 50 percent - in populations of species such as the northern lapwing (Vanellus vanellus), grey partridge (Perdix perdix) and skylark (Alauda arvensis) over that time.

DOF expert Niels Andersen found an overall loss in arable land populations of 2,950,000 birds after comparing figures with overall population estimates recorded by DOF in 2011. The result of the analysis shows a dramatic decrease in bird populations in farmland areas, Andersen said.

"This shows that we have lost a lot of everyday nature over the last 40 years. A few generations ago, many of us grew up in the country and had the lapwing's screech imprinted on our brains, or grew up listening to the skylark's song," he said.

Other species to be affected by the fall in populations include the yellowhammer, common linnet and swallow.

"The advance of agricultural production has had a price for biological diversity. The small biotopes where farmland birds could find a habitat are gone," Andersen said.

DOF chairperson Egon Østergaard said there was no quick fix to the problem. "This is caused by a changed in agricultural methods, and that animals now live in stables. We could appeal to farmers to not remove the last natural areas out there. But it is economic factors that determine how farmers must work their land," Østergaard said. Farmers who prioritise natural habitats should be more highly rewarded, he added. The DOF chairperson said he hoped changes to the EU's agricultural support policies in 2020 could bring potential improvements to the situation.
