The week in wildlife

Populations crashed in the second half of the last century, largely as a result of intensive agriculture. There were 118 known pairs in 1989. But with the help of wildlife-friendly farming in the area where they are still found, a reintroduction programme and a dedicated RSPB nature reserve, there were 862 breeding pairs last year. The number of pairs is a 25% increase on 2003 levels, the conservation organisations said.
