Does anyone know if there is any research on the impact of gas-gun birdscarers (as favoured by some arable farmers) on the breeding/ feeding activity of ground-nesting species such as skylarks, partridges, lapwings and meadow pipits?
Or indeed on yellowhammers, whitethroats, linnets and any other hedgerow songbirds that happen to be in the vicinity?
Presumably if these scarers frighten off woodpigeons, rooks and jackdaws, they do likewise to other species. They are not selective devices.
On a explosion-related subject, is there much known about the impact on bird populations (land and sea) of wars, past and present?
Was anything registered by any of the First World War poets such as Rupert Brooke and Wilfred Owen? Were any of them ornithologists?
