Raptors of Europe: Eagles, Hawks, Falcons, and Vultures

Updated: September 23, 2026

Europe supports 40 regularly and naturally occurring diurnal raptor species when the continent-wide scope of the European Red List of Birds is filtered to Accipitriformes and Falconiformes. The assemblage contains 29 species in Accipitridae, the Osprey in Pandionidae, and 10 falcons in Falconidae. It ranges from Arctic Gyrfalcons and wetland eagles to Mediterranean vultures, farmland harriers and woodland ambush hunters.

The 40-species total is tied to a defined boundary. BirdLife’s European assessment covers 54 countries and territories from Greenland, Iceland and Svalbard south to the Canary Islands, Malta and Cyprus, and from the Azores east to the Caucasus and Ural Mountains. It includes species native to Europe or occurring there naturally and regularly. A narrower peer-reviewed analysis based on regular breeding raptors counted 38 species, showing why totals from different European lists do not always match.

Why European Raptor Totals Differ

A list may count only breeding species, include regular winter visitors, add rare vagrants, extend Europe to the Caucasus and Atlantic islands, or treat owls as raptors. The checklist on this page includes regular diurnal species within BirdLife’s European Red List boundary. Owls and accidental visitors are excluded.

Falcons Are Not Hawks in a Taxonomic Sense

The English word raptor describes birds that share predatory adaptations, not one close evolutionary branch. Eagles, buzzards, kites, harriers, accipiters and Old World vultures belong to Accipitriformes. Falcons belong to Falconiformes, a separate lineage placed nearer parrots and passerines than to Accipitridae in modern avian classifications. The Osprey is also distinct enough to occupy its own family, Pandionidae. IOC classification

Order	Family	European Species	Forms Included
Accipitriformes	Accipitridae	29	Eagles, vultures, kites, harriers, buzzards, honey-buzzard and accipiters
Accipitriformes	Pandionidae	1	Osprey
Falconiformes	Falconidae	10	Falcons, hobbies, kestrels and Merlin

“Hawk” is especially imprecise. In a narrow European use it often refers to Accipiter species such as the Northern Goshawk and Eurasian Sparrowhawk. In broader English usage it may also be applied to buzzards, harriers or other medium-sized Accipitridae. Scientific names prevent that linguistic overlap from becoming a taxonomic error.

Taxonomy Is Moving Toward AviList

Scientific and English names were checked against IOC World Bird List v15.2. BirdLife maintains the taxonomy used for its conservation assessments and has begun aligning its work with AviList, first released in 2025. Species order and English names may therefore differ slightly between current checklists even where the underlying taxon is unchanged.

Wing Design Reflects Hunting Method

European raptors do not share one flight pattern or feeding system. Wing loading, tail length, body mass and feather shape reflect the airspace and prey used by each group. A Goshawk built for acceleration between trees has a different outline from a Griffon Vulture designed to remain aloft on rising air.

Raptor Form	Typical Outline	Characteristic Flight	Main Feeding Method
Large eagles	Broad wings, projecting head, medium to long tail	Soaring mixed with strong, deliberate wingbeats	Capture of mammals, birds, reptiles, fish or carrion use
Accipiters	Short rounded wings and a long tail	Rapid wingbeats followed by short glides	Ambush pursuit through woodland and enclosed habitats
Buzzards	Broad rounded wings and a medium tail	Circling, slope soaring and perch-based hunting	Small mammals, reptiles, birds, invertebrates and carrion
Harriers	Long wings and long tail	Low quartering flight with wings often held in a shallow V	Detection of prey in marshes, grassland and crops
Kites	Long wings and a forked or notched tail	Buoyant circling with constant tail adjustments	Small prey, refuse, fish remains and carrion
Falcons	Pointed wings and compact body	Fast pursuit, aerial interception, hovering or stooping	Birds, mammals and flying insects
Vultures	Long broad wings with separated primary feathers	Extended thermal and slope soaring	Carcass detection and scavenging
Osprey	Long angled wings with strong wrist bends	Hovering, gliding and feet-first plunge-diving	Fish capture

The 40 Regular Diurnal Raptors in the European Red List Scope

The tables below include every diurnal raptor assessed as regularly and naturally occurring within BirdLife’s European boundary. “Europe category” and “trend” refer to the 2021 regional assessment, not the current global category. LC means Least Concern, NT Near Threatened, VU Vulnerable, EN Endangered and CR Critically Endangered. Habitat and movement descriptions identify the species’ main European pattern rather than every habitat or seasonal exception. European Red List report

European and Global Categories Can Differ

A regional assessment measures extinction risk inside Europe. A species may be secure within the assessed European boundary but threatened across its full global range, or it may face high regional risk despite being more widespread elsewhere. Category and population direction are also separate measures.

Europe’s Four Vultures

Common Name	Scientific Name	Core European Ecology	Movement and Field Profile	Europe Category	Trend
Cinereous Vulture	Aegypius monachus	Open woodland, wooded dehesa and mountain landscapes	Resident or dispersive; broad, dark wings and a longer tail than Griffon Vulture	LC	Increasing
Bearded Vulture	Gypaetus barbatus	High mountains, cliffs and open alpine terrain	Mostly resident; long diamond-shaped tail and narrow, pointed-looking wings	NT	Increasing
Griffon Vulture	Gyps fulvus	Cliffs, open grazing country and mountain systems	Resident or dispersive; very broad wings, short tail and small projecting head	LC	Increasing
Egyptian Vulture	Neophron percnopterus	Dry open country, cliffs and pastoral landscapes	Mainly migratory in Europe; white adult with black flight feathers and wedge-shaped tail	VU	Decreasing

These species form a scavenger guild rather than four interchangeable carrion feeders. Griffon Vultures often open and consume soft tissue in groups. Cinereous Vultures can handle tougher material. Egyptian Vultures take smaller remains and a wider range of food, while Bearded Vultures are adapted to swallowing and digesting bones. Europe’s four-vulture restoration work therefore seeks to rebuild a set of complementary feeding roles. Vulture Conservation Foundation

Eagles, Snake Eagle and Osprey

Common Name	Scientific Name	Core European Ecology	Movement and Field Profile	Europe Category	Trend
Spanish Imperial Eagle	Aquila adalberti	Iberian woodland and open hunting mosaics	Resident or locally dispersive; large eagle with pale shoulder patches in adults	VU	Increasing
Golden Eagle	Aquila chrysaetos	Mountains, uplands, steppe and open rocky country	Mostly resident; long wings, projecting head and long tail	LC	Increasing
Bonelli’s Eagle	Aquila fasciata	Mediterranean cliffs, scrub and dry woodland mosaics	Mostly resident; long-tailed, powerful flight with relatively narrow wings	LC	Stable
Eastern Imperial Eagle	Aquila heliaca	Eastern lowlands, steppe edges and open woodland	Partial migrant; long, parallel-edged wings and pale nape in adults	LC	Increasing
Steppe Eagle	Aquila nipalensis	Steppe and semi-arid open country at Europe’s eastern edge	Long-distance migrant; broad-winged eagle with a long gape line	CR	Decreasing
Short-toed Snake Eagle	Circaetus gallicus	Dry open habitats with scrub, woodland edges and reptile prey	Long-distance migrant; pale underparts, dark hood and frequent wind-hovering	LC	Increasing
Greater Spotted Eagle	Clanga clanga	Wet forests, floodplains, marshes and lake districts	Migratory or dispersive; compact dark eagle with broad wings	VU	Decreasing
Lesser Spotted Eagle	Clanga pomarina	Eastern and central European forest–meadow mosaics	Long-distance migrant; smaller and more lightly built than Greater Spotted Eagle	LC	Increasing
White-tailed Sea-eagle	Haliaeetus albicilla	Coasts, estuaries, large rivers, lakes and wetlands	Resident or partial migrant; huge rectangular wings and short white tail in adults	LC	Increasing
Booted Eagle	Hieraaetus pennatus	Warm woodland, forest edges and open hunting country	Mainly migratory; small eagle occurring in pale and dark morphs	LC	Increasing
Osprey	Pandion haliaetus	Lakes, reservoirs, rivers, estuaries and coasts	Migratory or partial migrant; angled wings, dark wrist patches and fish-catching dives	LC	Increasing

“Eagle” does not identify one ecological type. Golden Eagles hunt across open uplands; spotted eagles depend more heavily on forest–wetland mosaics; White-tailed Sea-eagles use aquatic systems; Short-toed Snake Eagles specialise in reptile-rich landscapes. The Osprey is grouped here for ecological comparison but belongs to Pandionidae rather than Accipitridae.

Kites

Common Name	Scientific Name	Core European Ecology	Movement and Field Profile	Europe Category	Trend
Black Kite	Milvus migrans	Wetlands, rivers, farmland, settlements and open woodland	Mainly migratory in Europe; shallow forked tail and elastic circling flight	LC	Increasing
Red Kite	Milvus milvus	Farmland, pasture, woodland edge and uplands	Resident or partial migrant; deeply forked tail and long angled wings	LC	Increasing
Black-winged Kite	Elanus caeruleus	Open farmland, grassland and lightly wooded plains	Resident or dispersive; pale plumage, black shoulder patches and hovering hunts	LC	Stable

Red and Black Kites use their tails as active steering surfaces while circling and searching. The Black-winged Kite is structurally and behaviourally different: it frequently hovers over open ground and takes small mammals from short aerial searches or perches.

Harriers

Common Name	Scientific Name	Core European Ecology	Movement and Field Profile	Europe Category	Trend
Western Marsh Harrier	Circus aeruginosus	Reedbeds, marshes, wetlands and farmland	Partial migrant; large harrier with low quartering flight	LC	Stable
Hen Harrier	Circus cyaneus	Moorland, heath, bog, steppe and winter farmland	Migratory or partial migrant; buoyant flight with wings held in a shallow V	LC	Decreasing
Pallid Harrier	Circus macrourus	Eastern steppe, dry grassland and open farmland	Long-distance migrant; slim wings and narrow hand, especially in adult males	LC	Stable
Montagu’s Harrier	Circus pygargus	Grassland, cereal fields, heath and open marsh	Long-distance migrant; slender build and flexible, tern-like flight	LC	Decreasing

Harriers search close to the ground rather than remaining high in thermals. Their long wings, long tails and shallow dihedral improve control during low-speed turns over vegetation. Ground nesting exposes several populations to mowing, harvesting, trampling, fire and disturbance that would not affect cliff- or tree-nesting raptors in the same way.

Buzzards and the European Honey-buzzard

Common Name	Scientific Name	Core European Ecology	Movement and Field Profile	Europe Category	Trend
Eurasian Buzzard	Buteo buteo	Woodland edge, farmland, pasture and mixed landscapes	Resident or partial migrant; broad wings and highly variable plumage	LC	Increasing
Rough-legged Buzzard	Buteo lagopus	Arctic tundra in the breeding season and open lowlands in winter	Migratory; long wings, pale tail base and dark carpal patches	LC	Stable
Long-legged Buzzard	Buteo rufinus	Dry steppe, semi-desert, rocky slopes and open farmland	Resident or partial migrant; long wings and tail, often with warm rufous tones	LC	Increasing
European Honey-buzzard	Pernis apivorus	Woodland mosaics with clearings and insect-rich ground	Long-distance migrant; long tail, small pigeon-like head and flexible wings	LC	Stable

The European Honey-buzzard is not a typical Buteo buzzard. It feeds heavily on social wasps and their larvae, has scale-like facial feathering that offers protection around nests, and migrates to sub-Saharan Africa. Its long tail, small head and elastic wing action help separate it from the highly variable Eurasian Buzzard.

Woodland Hawks

Common Name	Scientific Name	Core European Ecology	Movement and Field Profile	Europe Category	Trend
Shikra	Accipiter badius	Dry woodland, groves and cultivated landscapes at Europe’s southeastern edge	Resident or short-distance migrant; small accipiter with rapid wingbeats	NT	Stable
Levant Sparrowhawk	Accipiter brevipes	Open woodland, groves and wooded river valleys in southeast Europe	Long-distance migrant; compact accipiter often seen in passage flocks	LC	Stable
Northern Goshawk	Accipiter gentilis	Mature forest and wooded mosaics	Resident or dispersive; powerful body, broad short wings and long tail	LC	Decreasing
Eurasian Sparrowhawk	Accipiter nisus	Woodland, scrub, farmland and urban areas	Resident or partial migrant; small, short-winged and long-tailed bird hunter	LC	Stable

Accipiters trade soaring efficiency for acceleration and manoeuvrability. Their short wings clear branches during tight turns, while the long tail acts as a brake and rudder. Females are larger than males, sometimes enough to alter the apparent proportions and prey range of the same species.

Falcons

Common Name	Scientific Name	Core European Ecology	Movement and Field Profile	Europe Category	Trend
Lanner Falcon	Falco biarmicus	Mediterranean and southeastern cliffs, dry open country and semi-desert	Mostly resident; large falcon with long wings and a pale head pattern	NT	Unknown
Saker Falcon	Falco cherrug	Eastern steppe, open farmland and lowland plains	Partial or long-distance migrant; broad-winged falcon adapted to open-country pursuit	EN	Decreasing
Merlin	Falco columbarius	Northern moor, tundra and open country; lowlands in winter	Migratory or partial migrant; small, fast falcon with direct flight	VU	Decreasing
Eleonora’s Falcon	Falco eleonorae	Mediterranean islands and sea cliffs	Long-distance migrant; late breeder timed to autumn passerine migration	LC	Stable
Lesser Kestrel	Falco naumanni	Dry farmland, steppe, villages and colony sites	Mainly migratory; colonial falcon with frequent hovering	LC	Stable
Peregrine Falcon	Falco peregrinus	Cliffs, coasts, mountains and cities	Resident or partial migrant; heavy-bodied falcon with pointed wings and a powerful stoop	LC	Increasing
Gyrfalcon	Falco rusticolus	Arctic tundra, sea cliffs and northern open country	Resident or dispersive; very large falcon with broad-based wings	LC	Stable
Eurasian Hobby	Falco subbuteo	Woodland edge, wetlands and open country	Long-distance migrant; slim, scythe-winged aerial hunter	LC	Stable
Common Kestrel	Falco tinnunculus	Farmland, grassland, cliffs and urban areas	Resident or partial migrant; frequent hovering and a long tail	LC	Decreasing
Red-footed Falcon	Falco vespertinus	Eastern grassland, steppe and open farmland with colony trees	Long-distance migrant; social falcon that often hunts insects in the air	VU	Decreasing

Falcons are not defined by one high-speed dive. Peregrines frequently intercept birds in open air, but kestrels use hovering searches, Merlins chase small birds close to the ground, hobbies take birds and insects in flight, and Sakers pursue prey across open steppe. Pointed wings unite the group, while wing breadth, tail length and hunting height separate its members.

Threat Category and Population Direction Measure Different Things

Thirty of the 40 species were assessed as Least Concern in Europe, but that does not mean every one was stable or rising. Ten species had decreasing European trends, including several classified as LC. A Red List category estimates regional extinction risk using population size, range and rate of change; the trend field reports whether numbers were moving upward, downward or remaining broadly stable during the assessment period.

Europe’s Main Raptor Regions Are Habitat Mosaics

Iberian and Western Mediterranean Landscapes

The Iberian Peninsula holds the entire breeding range of the Spanish Imperial Eagle and major European populations of Griffon, Cinereous and Egyptian Vultures. Dry woodland, dehesa, grazing land, cliffs and extensive open habitats occur close enough to support nesting, hunting and scavenging within the same regional system. Bonelli’s Eagle, Black-winged Kite, Red Kite, Lesser Kestrel and several migratory raptors add further ecological breadth.

Alps, Pyrenees, Carpathians and Balkan Mountains

Mountain chains provide cliff nesting, slope lift, open hunting ground and extensive livestock landscapes. Golden Eagles occupy many upland systems, while Bearded and Griffon Vultures depend on a smaller set of mountain strongholds and restored populations. The Balkans also connect European breeding grounds with migration routes toward Anatolia and the eastern Mediterranean.

Forest, Lake and Floodplain Belt

Central, eastern and northern European forest–wetland mosaics support White-tailed Sea-eagles, Ospreys, Greater and Lesser Spotted Eagles, Northern Goshawks and Eurasian Sparrowhawks. Large nest trees may lie within forest, while feeding takes place over lakes, rivers, marshes, meadows or agricultural clearings. Protecting a nest stand alone cannot retain this ecological arrangement if nearby feeding habitat is drained or simplified.

Eastern Steppe and Farmland

Open lowlands from central Europe eastward contain the European cores of Saker Falcon, Red-footed Falcon, Eastern Imperial Eagle, Long-legged Buzzard and several harriers. Scattered trees, old corvid nests, ground-squirrel colonies, field margins and low-intensity grassland can all affect breeding opportunities. Conversion to uniform crops may remove prey and nesting structure even when the landscape still appears open.

Arctic and Boreal Europe

Gyrfalcons, Merlins and Rough-legged Buzzards occupy Europe’s northern tundra and open boreal margins. Golden Eagles, White-tailed Sea-eagles, Ospreys and Northern Goshawks extend through parts of the same broad region but use different prey and nesting settings. Winter movement can carry northern raptors far into temperate farmland, coasts and wetlands.

Migration Concentrates Soaring Raptors at Narrow Crossings

Large eagles, vultures, buzzards and harriers save energy by using thermals and ridge lift. Rising air is weaker or absent over long stretches of open sea, so many soaring migrants concentrate where land narrows the crossing. The Strait of Gibraltar and Bosporus are major examples. Routes also pass through the central Mediterranean, the Black Sea margins and eastern Mediterranean land bridge.

Falcons and accipiters can sustain more powered flight than the heaviest soaring birds, yet many still follow productive coasts, valleys and peninsulas where prey and favourable winds concentrate. Migration routes are therefore species-specific networks rather than one shared European flyway.

Movement Pattern	European Examples	Ecological Consequence
Long-distance soaring migration	European Honey-buzzard, Lesser Spotted Eagle, Short-toed Snake Eagle	Strong concentration at land bridges and narrow sea crossings
Long-distance powered or mixed flight	Eleonora’s Falcon, Eurasian Hobby, Red-footed Falcon, Lesser Kestrel	Greater sea-crossing ability, although routes still follow prey and wind conditions
Partial migration	Red Kite, Common Kestrel, Western Marsh Harrier, White-tailed Sea-eagle	Some populations remain while others shift south or west
Juvenile dispersal	Griffon Vulture, Cinereous Vulture, Golden Eagle	Young birds may appear far beyond breeding cores without establishing a breeding range
Northern winter movement	Rough-legged Buzzard, Merlin, Gyrfalcon	Winter distribution changes with weather and prey availability

A record made during passage does not prove local breeding. Likewise, a dispersing juvenile beyond the usual range does not establish a resident population. Season, age and repeated breeding evidence are needed before a regional status is changed.

Flight Identification Begins with Structure and Behaviour

Colour is often the least reliable first feature at distance. Backlighting removes plumage detail, while age, sex, colour morph and moult can make members of the same species look unrelated. Wing proportions, tail form, flight rhythm, habitat and season usually narrow the possibilities before plumage markings are considered.

Observed Form	Most Likely Group	Supporting Behaviour	Common Source of Error
Pointed wings and compact body	Falcon	Fast direct flight, aerial pursuit, hovering or stooping	Hobbies, kestrels and large falcons still differ greatly in proportions
Short rounded wings with a long tail	Accipiter	Rapid flap–glide flight and sudden woodland pursuit	Female Sparrowhawks may be mistaken for male Goshawks without a scale reference
Long wings held in a shallow V near the ground	Harrier	Quartering over reeds, crops, heath or grassland	Sex and age produce sharply different plumages
Deeply forked tail	Red Kite	Continuous tail twisting during buoyant circling	Black Kite has a shallower fork that may disappear when the tail is spread
Broad wings and very short tail	Griffon Vulture or White-tailed Sea-eagle	Slow soaring with limited flapping	Head projection, wing shape and habitat must be checked together
Long angled wings with dark wrist marks	Osprey	Hovering above water and feet-first plunge-diving	Gulls can produce a similar bent-wing impression at poor angles
Broad rounded wings with variable underwing pattern	Buzzard	Circling, hovering in wind or watching from a perch	Eurasian Buzzard plumage is too variable for colour alone to be dependable
Very broad fingered wings and small head	Large vulture	Extended thermal soaring, often with other scavengers	Distance can conceal the longer tail and larger head of Cinereous Vulture

Apparent Size Is Easily Misjudged

A lone bird against an empty sky has no dependable scale. Distance, wing position and altitude can make a buzzard appear eagle-sized or make a large eagle seem compact. Comparative size becomes useful only when another bird, tree, structure or known landscape feature is close enough to provide scale.

Predators, Scavengers and Specialists Share the Same Food Web

Bird Hunters

Eurasian Sparrowhawks and Northern Goshawks use surprise and acceleration. Peregrines, Merlins and hobbies intercept birds in more open airspace. Eleonora’s Falcon delays breeding until late summer, allowing adults to exploit migrating passerines crossing Mediterranean islands while chicks are growing.

Mammal and Ground-Prey Hunters

Golden and imperial eagles can take medium-sized terrestrial prey, while buzzards and kestrels rely more heavily on small mammals. Harriers locate mammals and ground-nesting birds while flying slowly over vegetation. Prey composition changes by region, season, age and local availability, so no species should be reduced to one food item.

Fish, Reptiles and Invertebrates

Ospreys are dedicated fish hunters with reversible outer toes and spiny foot pads that improve grip. White-tailed Sea-eagles take fish but also birds, mammals and carrion. Short-toed Snake Eagles search reptile-rich open ground, while European Honey-buzzards excavate nests of social wasps. Lesser Kestrels and Red-footed Falcons may take large numbers of insects where seasonal swarms occur.

Carrion Use Extends Beyond Vultures

Vultures depend most heavily on carcasses, but kites, sea-eagles, buzzards and large eagles also scavenge. This overlap links raptor health to livestock carcass management, hunting ammunition, veterinary drugs, road mortality and deliberate poisoning. A contaminated carcass can expose several species during one feeding event.

Nesting Strategy Determines the Form of Disturbance

Nest Setting	Representative Raptors	Main Vulnerability
Cliffs and rock ledges	Griffon Vulture, Egyptian Vulture, Golden Eagle, Peregrine Falcon, Eleonora’s Falcon	Climbing, quarrying, aircraft, drones, repeated close observation and poorly placed energy infrastructure
Large forest trees	White-tailed Sea-eagle, Northern Goshawk, Black Kite, Cinereous Vulture, spotted eagles	Felling, forestry during breeding, loss of old nest trees and road access near nest stands
Ground vegetation	Hen Harrier, Montagu’s Harrier, Pallid Harrier	Harvesting, mowing, fire, trampling, predators and direct disturbance
Reedbeds and wetland vegetation	Western Marsh Harrier	Drainage, reed cutting, burning, fluctuating water levels and disturbance
Buildings, towers and bridges	Peregrine Falcon, Common Kestrel, Lesser Kestrel	Renovation during breeding, sealed cavities, unsafe ledges and collision hazards
Power pylons and artificial platforms	Saker Falcon, Osprey, Red-footed Falcon and other secondary nest users	Electrocution, maintenance disturbance and unstable nest structures, balanced against the value of artificial nest sites

Many falcons do not construct a substantial nest and instead use cliff scrapes, buildings or old nests made by other birds. Red-footed Falcons often depend on colonial corvid nests. Sakers may use pylons or artificial platforms in treeless lowlands. Nest-site conservation therefore includes retaining structures created by other species as well as protecting vegetation and cliffs.

Conservation Priorities Are Narrower Than the Full Species List

The 2025 European chapter of State of the World’s Raptors ranked the Egyptian Vulture and Spanish Imperial Eagle as the highest diurnal raptor priorities for the region after combining extinction risk, evolutionary distinctiveness and the share of each range within Europe. Red-footed Falcon, Greater Spotted Eagle, Pallid Harrier, Bearded Vulture, Cinereous Vulture and Saker Falcon also appeared among the leading priorities. The analysis used a broader raptor definition that included owls; only its diurnal results are applied here. Raptor conservation in Europe, 2025

Recovery and risk can occur at the same time. Spanish Imperial Eagles, Bearded Vultures, Cinereous Vultures, Griffon Vultures, White-tailed Sea-eagles, Red Kites and Peregrine Falcons have expanded in parts of Europe following legal protection, reintroduction, safer infrastructure, nest management or reduced exposure to former pollutants. Some remain restricted, fragmented or exposed to poisoning, collision and habitat change despite an upward regional trend.

Threats Act Through Different Biological Pathways

Pressure	Mechanism	Exposed Examples
Illegal poisoning	One poisoned bait or carcass can kill several scavengers and predators	Egyptian, Griffon and Cinereous Vultures; Red Kite; imperial eagles
Lead ammunition	Fragments remain in carcasses or discarded viscera and are ingested during scavenging	Vultures, sea-eagles, kites, Golden Eagles and other carrion users
Electrocution	A perched bird bridges energised conductors or a conductor and grounded structure	Saker Falcon, imperial eagles, vultures, kites and large perching raptors
Wire and turbine collision	A flying bird strikes a cable, rotor or associated structure	Large soaring raptors, vultures, eagles and migrants moving through constrained airspace
Agricultural intensification	Loss of prey, insects, fallow ground, nesting cover and structural variety	Red-footed Falcon, Lesser Kestrel, Saker Falcon, harriers and buzzards
Wetland alteration	Drainage and water-level change remove feeding and nesting habitat	Western Marsh Harrier, Greater Spotted Eagle, Osprey and White-tailed Sea-eagle
Forest management	Loss of old nest trees or breeding disturbance within occupied stands	Northern Goshawk, spotted eagles, Cinereous Vulture and White-tailed Sea-eagle
Illegal shooting and trapping	Direct mortality on breeding grounds and migration routes	Harriers, kites, falcons, eagles and vultures
Recreation near nests	Repeated close approach can interrupt incubation, feeding or fledging	Cliff-nesting eagles, falcons and vultures

Collision and Electrocution Are Separate Problems

Electrocution occurs when a bird completes an electrical circuit while perching, taking off or landing. Risk depends heavily on pole design, conductor spacing and insulation. Collision occurs when a bird physically strikes a wire, turbine or other structure during flight. Making a pole safe from electrocution does not automatically make nearby wires visible, and marking wires does not correct an unsafe energized crossarm.

Energy risk cannot be inferred from the technology alone. Location, topography, migration flow, roosts, nest sites, carcass availability, prey density and local flight height determine exposure. Surveying before construction and monitoring mortality after operation are necessary to detect risks that broad distribution maps may miss.

Protection Covers Birds, Nests, Habitats and Migration Routes

Within the European Union, the Birds Directive applies to naturally occurring wild bird species and requires Member States to prohibit deliberate killing or capture, destruction or damage of nests and eggs, egg collection and deliberate disturbance during breeding where the disturbance affects the Directive’s aims. It also requires habitat preservation and Special Protection Areas for listed and migratory species. These rules apply to all EU wild birds, not only species placed in a threatened Red List category. European Commission Birds Directive

The European Commission issued updated guidance on Articles 5 and 9 on 31 March 2026. The document explains the general protection system and the limited conditions under which Member States may use derogations. It does not replace national law, court decisions or site-specific restrictions. 2026 Articles 5 and 9 guidance

Conservation beyond the EU also depends on national wildlife laws, the Bern Convention, the Convention on Migratory Species and the CMS Memorandum of Understanding on African-Eurasian migratory birds of prey. Migrants may breed under one legal system, pass through several others and winter outside Europe. Mortality at any stage can reduce the breeding population observed thousands of kilometres away.
