Montagu's Harrier (Circus pygargus) lives in open grasslands across Europe, Asia, Africa. It feeds on small mammals insects. Its conservation status is Least Concern.
Fascinating facts about the Montagu's Harrier
- Montagu's harrier looks larger than it is because its wings spread 97-115 cm (38-45 in) while its body measures only 43-47 cm (17-19 in) and weighs just 265 g in males and 345 g in females. This huge wing surface relative to a tiny mass lets it glide effortlessly over fields, a design that lets the raptor conserve energy while scanning for prey across vast open landscapes.
- Up to 70 % of the European Montagu's harrier population now nests in artificial habitats like cereal fields, making the species extremely vulnerable to early harvesting. When farms are the only option, the birds choose grasslands and crops such as wheat, barley, oats and colza, and a single nest can be lost if the field is cut before fledging. This dependence on farmland ties their survival directly to modern agricultural practices.
- Montagu's harriers are long-distance migrants: birds from Eurasia winter in sub-Saharan Africa, while eastern populations travel to the Indian subcontinent. In Europe the first birds depart in early August and most have left by mid-October, crossing the Mediterranean at many points. Some western birds stop at the Gulf of Guinea, but eastern individuals can journey as far as South Africa.
- While hunting, Montagu's harriers fly low at about 30 km/h (19 mph) along fixed routes. Males may travel up to 12 km (7.5 mi) from the nest to find food, whereas females stay within 1 km (0.62 mi). This division of labor lets the pair feed the young 7-10 times a day once the chicks hatch.
- A global meta-analysis of 104 bird species found that large, migratory birds like Montagu's harrier have suffered a drop in offspring production over the past 50 years as temperatures rose about 1 °C. The study highlighted Montagu's harrier as one of the few large-bodied species showing a clear decline, warning that warming climates could further reduce their breeding success and ripple through ecosystems that rely on their predation.
