Many buzzard species do migrate, but the answer ranges from “barely at all” to “thousands of kilometers across continents and oceans” depending on which buzzard you are talking about. The genus Buteo alone contains dozens of species spread across every continent except Antarctica, and their migratory habits vary from fully sedentary to epic trans-Saharan journeys. Add in the honey buzzards, the grey-faced buzzard, and the rough-legged buzzard, and the picture gets even more varied. Whether a given buzzard population moves at all, how far it travels, and when it departs are shaped by geography, climate, food supply, and even the individual bird’s age.
The Common Buzzard Is a Partial Migrant
The common buzzard (Buteo buteo) is the species most people in Europe picture when they hear the word “buzzard,” and its migration story is one of the more nuanced in the raptor world. Populations in western and southern Europe tend to stay put year-round. A buzzard breeding in the United Kingdom, France, or Spain has little reason to leave; winters are mild enough that prey remains accessible. But as you move north and east across Europe, the picture shifts. Birds breeding in Scandinavia, the Baltic states, Poland, and Russia face harsh winters that freeze the ground and bury prey under snow, so those populations head south in autumn.
Where exactly they go depends on what geographic barriers sit in their path. Research on common buzzards wintering in eastern Europe found that populations on either side of the Carpathian Mountains followed different patterns, with weather oscillations in the North Atlantic and the Arctic influencing how many birds settled in a given wintering area each year.1PubMed Central. Common Buzzards wintering strategies as an effect of weather conditions and geographic barriers In milder winters, some common buzzards barely move at all; in severe ones, the same population might push hundreds of kilometers further south. This flexibility makes the common buzzard a textbook partial migrant, where the decision to move is not hardwired but responsive to conditions on the ground.
The Steppe Buzzard Goes the Distance
The steppe buzzard (Buteo buteo vulpinus) is a subspecies of the common buzzard, but its lifestyle is dramatically different. Breeding across the steppe and forest-steppe zones from eastern Europe through Central Asia, steppe buzzards are obligate long-distance migrants. They head to sub-Saharan Africa and southern Asia for the winter, covering thousands of kilometers each way. Because they rely on thermal updrafts to gain altitude and then glide long distances between thermals, they concentrate at geographic bottlenecks like the Bosporus Strait and the Jordan Valley, where huge flocks can be observed spiraling upward in columns of rising air.
Studies tracking steppe buzzard flight behavior found that these birds actively adjust their gliding speed in response to how fast they were climbing in the last thermal. When a strong thermal had lifted them quickly, they glided faster between thermals, trading altitude for speed and maximizing their cross-country pace.2Oxford Academic (Behavioral Ecology). Optimal flight behavior of soaring migrants: a case study of migrating steppe buzzards, Buteo buteo vulpinus This kind of real-time optimization is part of what makes soaring migration so efficient: the birds burn very little energy compared to species that flap their way across continents.
Honey Buzzards and the Trans-Saharan Journey
European honey buzzards (Pernis apivorus) are not closely related to “true” buzzards in the genus Buteo, despite the shared name. They breed across much of Europe and migrate to tropical West and Central Africa for the winter, making them among the longest-distance migrants of any raptor in the Western Palearctic. Satellite tracking has shown that adult honey buzzards cross the Mediterranean at the Strait of Gibraltar and continue across the Sahara to wintering grounds stretching from Sierra Leone to Cameroon.3Oikos. Age‐dependent migration strategy in honey buzzards Pernis apivorus tracked by satellite
One tracked individual breeding in northern Hungary returned to the same wintering area in northern Cameroon year after year, using a large-scale loop migration. Its spring route was consistently shorter and faster than its autumn route, with the bird willing to make longer open-water crossings in spring when the urgency to reach the breeding grounds was highest.4Avocetta. Repeated large scale loop migrations of an adult European Honey Buzzard This loop pattern, where outbound and return routes differ substantially, is common among soaring migrants and reflects differences in prevailing winds and thermal availability between seasons.
Why Open Water Is a Problem for Soaring Birds
If you have ever wondered why migrating raptors funnel through narrow straits rather than flying straight across the sea, the answer comes down to energy. Soaring birds like buzzards ride columns of warm rising air over land, gaining altitude for free and then gliding forward. Over open water, that free lift largely disappears because the sea surface heats unevenly and produces much weaker thermals than land does. A buzzard caught over open water with no updrafts has to switch to energy-expensive flapping flight or lose altitude rapidly.
Research on honey buzzards crossing the Mediterranean in autumn found that the main factor determining how far they were willing to fly over open sea was not wind speed or direction but the potential for uplift over the water surface. Using four decades of sea-surface temperature data, researchers mapped what they called the “energy seascape” and discovered that early-migrating adults were more likely to encounter poor soaring conditions over the sea, while juveniles departing later in autumn faced less hostile and sometimes even favorable conditions for soaring.5PubMed Central. Dynamics of the energy seascape can explain intra-specific variations in sea-crossing behaviour of soaring birds This helps explain a pattern that had puzzled researchers: adult honey buzzards tend to hug coastlines and cross at the narrowest points, while juveniles sometimes take surprisingly bold routes over open water. The juveniles are not reckless; they simply encounter better atmospheric conditions by the time they depart.
Age Matters in Migration Strategy
The honey buzzard findings point to a broader pattern seen across multiple buzzard species: adults and juveniles often migrate differently. Adults tend to follow more direct, energy-efficient routes and stick to familiar corridors they have used before. They leave earlier, arrive sooner, and show strong site fidelity to both their breeding and wintering grounds. Juveniles, migrating for the first time, lack this experience and may take longer, more meandering routes. In some species, first-year birds do not return to the breeding grounds at all during their first summer, instead lingering somewhere along the migratory route or in the wintering area.
These age-related differences are not just quirks of inexperience. As the energy seascape research showed, the timing of departure actually changes the atmospheric conditions a bird encounters, so an adult leaving in late August and a juvenile leaving in late September face genuinely different physical environments along the same route.5PubMed Central. Dynamics of the energy seascape can explain intra-specific variations in sea-crossing behaviour of soaring birds What looks like a choice is partly a consequence of circumstance.
Eastern Buzzards and the Sea of Japan Divide
On the other side of the world, the eastern buzzard (Buteo japonicus) presents a fascinating case of two subspecies with starkly different migratory programs despite overlapping in winter. GPS tracking and genetic analysis of 28 eastern buzzards in Japan revealed that the two subspecies, B. j. japonicus and B. j. burmanicus, follow completely different migration routes. The japonicus subspecies migrates within the Japanese Archipelago, moving north in spring and south in autumn without ever leaving the island chain. The burmanicus subspecies, by contrast, crosses to the Eurasian continent and flies north along the eastern coast of mainland Asia to breed.6Ibis. GPS tracking of the two subspecies of the eastern buzzard (Buteo japonicus) reveals a migratory divide along the Sea of Japan
Their breeding ranges do not overlap, which means the Sea of Japan acts as a migratory divide: a geographic line separating populations that take fundamentally different routes. Separate satellite tracking work followed 22 eastern buzzards wintering in Japan on a total of 65 northward and 55 southward migrations over several years, with many individuals routing through Sakhalin Island on their way to and from the continent.7PubMed. Satellite Tracking of Migration Routes of the Eastern Buzzard (Buteo japonicus) in Japan through Sakhalin The consistency of individual routes from year to year was striking, suggesting that once a buzzard learns a migratory path, it tends to stick with it.
Grey-Faced Buzzards and Island Hopping in the Pacific
Not all buzzard migrations follow overland routes between continents. The grey-faced buzzard (Buteo soloensis) breeds in eastern Asia and migrates south through the Philippines and into Southeast Asia, a journey that requires crossing substantial stretches of open ocean. Unlike the honey buzzard’s Mediterranean crossing, the grey-faced buzzard’s route involves hopping between islands in an archipelago, and each hop poses a risk.
Modeling of grey-faced buzzard migration through the Philippines found that the birds’ optimal strategy was to find the shortest route to an exit point that offered the greatest access to stopover habitats and the fewest open-water crossings under wind resistance.8Journal of Engineering, Environment and Agriculture Research. GIS-Modeling of Island Hopping Through the Philippines Demonstrates Trade-Offs Migrant Grey-Faced Buzzards During Oceanic Crossings In other words, the birds are not just minimizing total distance; they are balancing distance against the availability of places to rest and feed along the way. Similarly, Oriental honey buzzards tracked through Indonesia used stopover habitats heavily influenced by food availability, with suitable stopover areas covering most of the landscape in places like East Belitung.9Procedia Environmental Sciences. Spatial Distribution Model of Stopover Habitats Used by Oriental Honey Buzzards in East Belitung Based on Satellite-tracking Data Stopover sites are not just rest breaks; they are refueling stations, and their quality can determine whether a bird completes its migration successfully.
Rough-Legged Buzzards and Arctic Snowmelt
The rough-legged buzzard (Buteo lagopus) breeds on the Arctic tundra across both the Old and New Worlds and migrates south in winter to temperate grasslands and farmland. Its spring migration is especially interesting because it is closely tied to the northward progression of snowmelt. Satellite tracking showed that rough-legged buzzards adjusted their pace tightly to the retreating snow line, sometimes pausing or even retreating southward when they encountered snow-covered ground ahead of them.10Nature. Arctic avian predators synchronise their spring migration with the northern progression of snowmelt
This makes ecological sense: rough-legged buzzards feed heavily on lemmings and voles, which are inaccessible under deep snow. Arriving before the snow melts would mean starvation, while arriving too late means losing prime nesting territories. The species also shows occasional irruptive movements, where large numbers suddenly appear well outside their normal winter range. These irruptions tend to coincide with crashes in rodent populations on the breeding grounds, pushing the birds further south or into unusual areas in search of food. If you live in the northern United States or southern Canada and one winter you suddenly see rough-legged buzzards everywhere, a rodent crash up north is the likely explanation.
The North American “Buzzard” Confusion
In North America, “buzzard” is a colloquial term for vultures, especially the turkey vulture (Cathartes aura). This creates endless confusion when discussing buzzard migration in an international context. Turkey vultures are migratory across much of their range, with northern populations moving south for winter, but their flight ecology is quite different from that of Buteo hawks. Turkey vulture migration was studied using satellite-reporting GPS sensors across ten migration events, revealing that the birds depended heavily on turbulent kinetic energy in the atmospheric boundary layer to cover long distances.11PubMed Central. Movement ecology of migration in turkey vultures A turkey vulture fitted with a heart-rate logger showed only a small increase in heart rate as daily flight distance increased, confirming that soaring migration is remarkably cheap in metabolic terms.
If someone in Texas says “the buzzards are back,” they mean turkey vultures returning from their wintering grounds in Mexico or Central America. If someone in England says “the buzzards never left,” they mean common buzzards that stayed through winter. Both statements can be true simultaneously, about completely different birds. For clarity in this article and in ornithology generally, “buzzard” refers to hawks in the genus Buteo and its close relatives, not to New World vultures.
Wind Turbines and the Risks of Migration
Migration is inherently dangerous. Birds face storms, starvation, predation, and exhaustion over open water. But human-made hazards are adding new risks, particularly for species that soar at the altitudes where wind turbine blades spin. In Brandenburg, Germany, collisions with wind turbines have become a recognized threat to common buzzards, adding to pressure already placed on the population from habitat changes and other human activities.12PLOS ONE. Predicting strike susceptibility and collision patterns of the common buzzard at wind turbine structures in the federal state of Brandenburg, Germany Brandenburg is one of Germany’s most wind-turbine-dense states, and because common buzzards spend much of their time soaring in search of prey at heights that overlap with rotor sweep zones, they are more vulnerable than many other species.
The collision risk is not limited to migration. Resident buzzards hunting near turbines face the threat year-round, and breeding birds may be especially at risk when making repeated foraging trips to feed chicks. Mitigation efforts have focused on maintaining buffer distances between turbines and known nesting sites, though this is complicated by the fact that buzzards are widespread and nest at high densities in favorable habitat. For migratory populations passing through wind farm areas, the risk window is shorter but still real, especially at locations where topography funnels birds through narrow corridors.
Historical Persecution and Population Recovery
The migration patterns we observe today are not static; they reflect centuries of human influence on buzzard populations. In the United Kingdom, common buzzards were once treated as vermin, with bounties paid for their carcasses going back more than five hundred years. Gamekeeping during the eighteenth and nineteenth centuries eradicated them from much of eastern Britain. Then in the 1950s, the myxomatosis virus wiped out rabbit populations across the country, and since rabbits were a primary prey species, buzzard numbers crashed further in an unintended cascade.13Royal Society Publishing. Anticipation of common buzzard population patterns in the changing UK landscape
Since legal protection was introduced and rabbit populations partially recovered, common buzzards have recolonized much of Britain and are now the most abundant raptor in the country. This recovery has changed the local picture of buzzard movement: where once you might have needed to travel to Wales or Scotland to see one, they are now widespread across England as well. But the UK population is largely sedentary, so what has expanded is not migration but year-round residency. The more interesting migration dynamics play out on the continent and in Asia, where the interplay of harsh winters, geographic barriers, and prey availability continues to shape which buzzards stay and which go.
How Climate Change Is Shifting the Picture
Warming winters across Europe are already altering buzzard migration. As freezing conditions become less severe and less prolonged in northern and eastern Europe, some common buzzard populations that previously migrated south are beginning to overwinter closer to their breeding grounds. This “short-stopping,” where migrants halt earlier along their route because conditions are tolerable, has been documented in several raptor species and appears to be accelerating.
The consequences are not straightforward. A buzzard that stays north saves the energy cost and risk of migration, but it also gambles on winter food availability. A sudden cold snap after a mild start to winter can leave short-stopping birds in trouble, stranded in areas where prey is suddenly buried under ice. For populations wintering east of the Carpathians, large-scale atmospheric oscillations continue to drive year-to-year variation in buzzard abundance, meaning that climate change does not just raise the average temperature but also changes the volatility of winter weather that these birds must navigate.1PubMed Central. Common Buzzards wintering strategies as an effect of weather conditions and geographic barriers
For arctic breeders like the rough-legged buzzard, the stakes are different. Earlier snowmelt means breeding grounds become accessible sooner, but it also disrupts the timing relationship between snow retreat, vegetation growth, and rodent population cycles that the birds depend on. A mismatch between the buzzard’s arrival and peak prey availability could reduce breeding success even if migration itself becomes easier. The evidence here is still emerging, and researchers remain cautious about predicting exactly how each species will adjust. What seems clear is that “do buzzards migrate” is a question with an answer that is itself migrating, shifting gradually as the climate these birds evolved in changes underneath them.
