Conservation efforts in the United Kingdom to preserve a rare bird species have received a significant boost from the remarkable breeding success of a male bird known as AU. Mark Thomas, a conservationist, credits AU for significantly contributing to the protection of the Montagu’s harrier population in the UK. AU, a 10-year-old bird, has fathered 16 offspring, with 10 born in the last two years alone, earning him the title of an “absolutely prolific” male.
The Montagu’s harriers, migratory birds of prey, face a declining global population and are classified as a species of least concern on the International Union for Conservation of Nature’s Red List. In the UK, the Royal Society for the Protection of Birds (RSPB) has been working tirelessly to prevent the extinction of these rare birds. The UK population of Montagu’s harriers, which dwindled from 30 breeding pairs in the 1950s to zero in the ’70s, has shown signs of recovery, thanks in part to AU’s breeding success.
AU’s acrobatic mating displays have attracted the attention of female harriers, leading to successful nesting and the birth of six chicks this year. Conservationists are hopeful that AU’s offspring, especially his male descendants, will return to the UK to breed in the future. To protect the newly hatched chicks, researchers have set up barriers around their nests in undisclosed locations on British farms.
In a groundbreaking move, the RSPB has equipped two juvenile harriers with satellite trackers for the first time. This technology will enable researchers to monitor the birds’ migration patterns and potentially locate their nests upon their return to the UK. Thomas and his team are eager to analyze the data from these trackers, as it provides valuable insights into the behavior and movements of young Montagu’s harriers.
