Conservationist Mark Thomas recently highlighted the significant role played by a male Montagu’s harrier in maintaining the British population of this rare bird species. Known as AU, the male bird has been incredibly successful in siring offspring, with a total of 16 juveniles, including 10 in the past two years. Thomas, who leads the species conservation efforts at the Royal Society for the Protection of Birds (RSPB), emphasized the crucial contribution of AU in supporting the species within the U.K.
Montagu’s harriers are migratory birds that breed in Europe after spending their winters in Africa and parts of Asia. Despite being classified as a species of least concern globally, their population has been dwindling, particularly in the U.K. where they have faced a rapid decline. The species, which once had around 30 breeding pairs in the 1950s, plummeted to zero in the ’70s before seeing a slight resurgence to 13 pairs in the mid-2000s. However, another decline followed, with zero breeding pairs reported between 2000 and 2003.
The recent success in safeguarding the Montagu’s harriers in the U.K. can be largely attributed to AU’s breeding prowess. His acrobatic mating displays have attracted several females, leading to successful nestings and the birth of six chicks this year. Conservationists are optimistic about the future, especially with the introduction of satellite trackers on two juvenile harriers to monitor their migration patterns and potential return for breeding. This innovative approach marks a significant step in ensuring the continued survival of this rare bird species.
