Conservationist Mark Thomas shared insights in an interview about the remarkable efforts to safeguard a rare bird species in the United Kingdom. The Montagu’s harrier population in Britain has found a lifeline in a particularly successful male bird known as AU, who has played a crucial role in breeding and raising offspring. Thomas, who leads the Royal Society for the Protection of Birds (RSPB) on this species, emphasized AU’s exceptional contribution to sustaining the species in the UK.
Montagu’s harriers are migratory raptors that breed in Europe after wintering in Africa and parts of Asia. While facing a global population decline, these birds are classified as a species of least concern on the International Union for Conservation of Nature’s Red List. In the UK, their numbers have dwindled significantly over the years, with a resurgence led by AU’s breeding success garnering attention and hope for the species’ survival.
AU’s impressive track record includes fathering multiple chicks each year, with his acrobatic displays attracting female harriers for mating. This year, AU’s courtship drew the interest of three females, resulting in successful nesting with two of them. The offspring from these nests, including six chicks, offer promise for the species’ future, with hopes that AU’s sons will return to breed in the UK.
To ensure the safety of the new hatchlings, conservationists have taken proactive measures by concealing the nest locations and implementing protective barriers. The RSPB’s monitoring efforts include attaching satellite trackers to juvenile harriers for the first time, allowing researchers to track their migration patterns and potential return to breeding grounds in the UK. This innovative approach aims to gather valuable data for the ongoing conservation and protection of the Montagu’s harrier population in the UK.
