Rough-Legged Hawk (Buteo lagopus) lives in arctic tundra across Arctic and Subarctic regions of North America and Eurasia. Its conservation status is Least Concern.
Fascinating facts about the Rough-Legged Hawk
- When daylight stretches from a short 7.2 hours to a full 24, these buzzards expand their daily activity from 13.1 hours to nearly 19 hours. The longer daylight lets them spread their energy over more hours, lowering the hourly cost of living while still meeting the 80-120 g of food they need each day.
- Rough-legged buzzards feast on small mammals for 62-98 % of their meals, with lemmings and voles alone making up 80-90 % when they're abundant. This reliance means forcing them to switch to birds, hares or even rabbits. Their diet's tight link to lemming cycles highlights how climate-driven rodent crashes could ripple through the whole Arctic food web.
- If a rough-legged buzzard survives its first year, it can reach 19 years in the wild, but most never make it past two. The average lifespan is just about 2 years, reflecting high juvenile mortality from starvation, freezing, predators and human hazards.
- At 46-68 cm long with a 120-153 cm wingspan, the rough-legged buzzard can tip the scales from a feather-light 600 g to a hefty 1,660 g. Adult males average 822 g in summer, swelling to 1,027 g by winter, while females grow from 1,080 g to 1,278 g.
- During autumn migration the buzzard's "foxtrot" pattern sends it sprinting 1,500 km in about two weeks, roughly 100 km each day, across forested regions, then slowing to a crawl of 10 km per day as it drifts over open fields for another 1,000 km.
