Huge declines in woodland birds

The nightingale has effectively vanished from woodlands across the UK.

A 30-year survey of British woodland birds has found that its population has fallen by more than 95%.

Seventeen other bird species have also declined significantly, many of which overwinter in tropical west Africa where their habitat is being destroyed.

Numbers of starling, linnet, bullfinch and willow warbler all crashed, while 12 species, including the blackcap, magpie and collared dove, increased.

These startling trends in the populations of some of the UK's best known woodland birds comes from the British Trust for Ornithology's (BTO) Common Bird Census, which gathered data on 49 species between 1967 and 1999.
