Conservationists in the United Kingdom have been striving to prevent the extinction of a rare bird species known as the Montagu’s harrier. Recent efforts to safeguard the British population of these birds have been notably successful, largely due to the exceptional breeding abilities of a male bird described as “absolutely prolific” by conservationist Mark Thomas.
The male bird, named AU after the chemical symbol for gold, has fathered a total of 16 offspring, with 10 of them being born in the past two years alone. Thomas, who serves as the species lead for the Royal Society for the Protection of Birds (RSPB), emphasized AU’s crucial role in sustaining the species within the U.K.
Montagu’s harriers are migratory birds that spend their winters in Africa and parts of Asia, returning to Europe each spring for breeding. Despite being classified as a species of least concern on the International Union for Conservation of Nature’s Red List, the global population of Montagu’s harriers is dwindling.
In the U.K., the RSPB has observed a rapid decline in the already scarce bird population, with numbers dropping from around 30 breeding pairs in the 1950s to zero in the 1970s. The population saw a slight recovery to 13 pairs in the mid-2000s before plummeting again to zero between 2000 and 2003.
Thomas expressed the urgency of conserving the existing bird population, emphasizing the significance of recent successes in breeding efforts, particularly attributed to AU’s contributions. AU, also known as the “golden boy,” successfully raised six chicks this year, with the offspring evenly distributed between two nests located on a British farm.
To protect the nests and ensure the survival of the hatchlings, conservationists have implemented security measures, including constructing barriers to shield the birds from predators and other threats. The RSPB’s collaboration with farmers plays a crucial role in safeguarding the chicks and supporting the growth of the Montagu’s harrier population in the U.K.
In a new initiative, the RSPB has equipped two juvenile harriers with satellite trackers for the first time. These trackers will enable researchers to monitor the birds’ migration patterns and potential return to the U.K. for breeding in the future. Thomas expressed excitement about this tracking initiative, highlighting the valuable insights it may provide for the conservation efforts of the Montagu’s harriers.
