Bird populations across Europe have experienced sharp declines over the past 30 years, with the majority of losses from the most common species, say the University of Exeter, the RSPB and the Pan-European Common Bird Monitoring Scheme (PECBMS) in a new study. However, numbers of some less common birds have risen.
The study, published today in the journal
Ecology Letters, reveals a decrease of 421 million individual birds over 30 years. Around 90 percent of these losses were from the 36 most common and widespread species, including house sparrows, skylarks, grey partridges and starlings, highlighting the need for greater efforts to halt the continent-wide declines of our most familiar countryside birds.
Richard Inger from the University of Exeter said: "It is very worrying that the most common species of bird are declining rapidly because it is this group of birds that people benefit from the most."
"It is becoming increasingly clear that interaction with the natural world and wildlife is central to human wellbeing and significant loss of common birds could be quite detrimental to human society."
