Study links huge decline in European birds to farming and habitat loss

Bird populations across Europe have experienced a sharp decline over the past 30 years due to modern farming methods and the loss of habitats, according to a new study that brought together data on 144 species from thousands of scientific surveys in 25 countries. The study, published in the journal "Ecology Letters", suggest that bird populations have dropped by 421 million across Europe since 1980, with 90% of the losses from the 36 most common bird species, including sparrows, skylarks and starlings. Dr Richard Inger, an ecologist at the University of Exeter who led the study, said: “It is very worrying that the most common species of bird are declining rapidly because it is these groups of birds that people benefit from the most.” Birds provide key ecosystem services. They help to control agricultural pests and play a vital role in decomposition, pollination and seed dispersal. The authors say the decline in bird populations can be linked to agricultural intensification, deterioration of the quality of the environment and habitat fragmentation, which has reduced areas that birds need for feeding and nesting. According to the study, conservation efforts tend to be focused on rarer species, such as white storks, whose populations are now increasing. However, measures should also address issues affecting common birds, for example those traditionally associated with farmland, since they exist in higher numbers and play a bigger role in maintaining the ecosystem. The authors stress the need for greater funding and efforts to protect common bird species, such as changing farming practices, implementing effective agri-environment schemes and increasing green spaces in urban areas.
