“Of 22 sites surveyed in 2013, this farm had more pairs of waders than any other. With 80 pairs in total, numbers of farmland waders were high enough for the farm to be regarded as a key wader site.” (http://www.rspb.org.uk/media/releases/371107-curlew-champion-meets-his-match)
A similar survey is tracking the haunts of regular wellington boots.
“Turtle doves are the fastest declining species – down 95 per cent since 1970 – and reports from earlier this year suggest it is the worst year ever for sightings. Other species hit hard include lapwings, which are down 63 per cent since 1970; corn buntings, down 90 per cent; and skylarks, down 59 per cent.” (http://www.rspb.org.uk/media/releases/355662-farmland-bird-numbers-continue-to-fall)
At this rate soon we won’t be able to move for these birds flapping around our ankles.
