A pair of Montagu\u2019s harriers have raised four chicks in an English wheat field, the first success for Britain\u2019s rarest breeding bird since 2019.<\/p>\n
The fledglings took their maiden flights this week after being closely monitored by the RSPB and the local farmer, with a protective wire-mesh fence installed around the nest to repel predators such as foxes.<\/p>\n
The location is being kept secret because it is private farmland, but also to enable the young birds to feed up and grow in strength without disturbance from over-enthusiastic birders.<\/p>\n
The Montagu\u2019s harrier has long been a rare species in Britain but after a recent high of nine successful nests in 2011 its population has dwindled, with no fledging successes for six summers.<\/p>\n
The migratory raptor overwinters in sub-Saharan Africa before heading north to nest in Europe, often in arable fields. In recent decades its nests have been accidentally destroyed by agricultural intensification, such as mechanised harvesting and crop-spraying, as well as breeding birds struggling in wetter summers.<\/p>\n
In its remaining strongholds, such as France and Spain, many nests in cereal fields are protected from ground-nesting predators by installing temporary small metal fences around them.<\/p>\n
The pair were first spotted in May and closely monitored by a local volunteer and the RSPB, with a drone being used under licence to locate the nest. Once the youngsters hatched, the nest was protected with fencing earlier this month.<\/p>\n
Mark Thomas, the species lead for Montagu\u2019s harriers at the RSPB and an expert in protecting vulnerable birds of prey, said: \u201cWe are overjoyed that a pair have returned, they managed to find each other and through the close protection of a dedicated farmer and the RSPB have managed to raise four youngsters.\u201d<\/p>\n
The farmer, who is not named to protect the location, said: \u201cIt\u2019s fantastic to have these amazing birds on the farm and a just reward for the extensive conservation work we have been undertaking for decades.\u201d<\/p>\n
Adult harriers are often site-faithful, raising hopes they may return to the same spot next summer.<\/p>\n
Rings on the parent birds have revealed that the male is a long-lived bird from a British nest in 2015, while the female fledged from a French nest in 2023.<\/p>\n
Thomas added: \u201cThis Anglo-French alliance could just be the springboard needed to save this species in Britain.\u201d<\/p>\n
