A bird survey that was reported to have taken place on a managed grouse moor in the Pennines has been widely quoted in the media this week. The report arising suggested that 800 pairs of Lapwing, 400 pairs of Curlew and 100 pairs of Golden Plover were present, and that 89 species of bird were seen. These results have been used as evidence that moorland managed for grouse shooting is good for birds.
These figures have been attributed to the British Trust for Ornithology (BTO), but this claim is erroneous. This fieldwork was not carried out by the BTO and did not use the rigorous statistical methods employed by BTO in order to produce accurate estimates of this type.
