Buteo rufinus

The long-legged buzzard (Buteo rufinus ) is a bird of prey found widely in several parts of Eurasia and in North Africa. This species ranges from Southeastern Europe down to East Africa to the northern part of the Indian subcontinent. The long-legged buzzard is a member of the genus Buteo, being one of the larger species therein. Despite being relatively powerful, it is considered a rather sluggish raptor overall. Like most buzzards, it prefers small mammals such as rodents, including gerbils, ground squirrels, voles and rats, also taking reptiles, birds and insects as well as carrion. Adaptable to a variety of habitats, long-legged buzzards may nest on a variety of surfaces, including rocks, cliffs and trees. it is a typical buzzard in its reproductive biology. The long-legged buzzard is widely distributed and appears to be quite stable in population. Therefore, it is considered as Least Concern by the IUCN.

This is one of the largest species of the Buteo genus. Only two species, the upland buzzard (Buteo hemilasius ) and the ferruginous hawk (Buteo regalis ), notably exceed the average and maximum weight of nominate long-legged buzzards or attain similar wingspans, but several other species of the genus broadly overlap in body size with the long-legged buzzard (for instance the Galapagos, rufous-tailed and red-tailed hawks and the Augur, rough-legged and jackal buzzards). Length can range from 50 to 66 cm (20 to 26 in) and wingspan from 112 to 163 cm (3 ft 8 in to 5 ft 4 in). Mean wingspan may be about 145 cm (4 ft 9 in), with wingspans surely rivaling the upland buzzard as the greatest of all Buteo. The long-legged buzzard displays the typical size sexual dimorphism in favor of females, as they may be to 15% larger and can average up to 30% heavier. The mean body mass of males is 1,035 g (2.282 lb), amongst a sample of 8 with weights ranging from 590 to 1,281 g (1.301 to 2.824 lb), while the mean was 1,315 g (2.899 lb), in a sample of 11 ranging from 945 to 1,760 g (2.083 to 3.880 lb). Meanwhile, the weights of migrating long-legged buzzards migrating in Eilat were 1,182 g (2.606 lb) in mature buzzards and 1,047 g (2.308 lb) in second-year juveniles. The measurements of live Indian long-legged buzzards were 1,000 to 1,300 g (2.2 to 2.9 lb) with slighter lengths of 46 to 55 cm (18 to 22 in) and wingspans of 129 to 150 cm (4 ft 3 in to 4 ft 11 in). Among standard measurements, nominate subspecies males attain a wing chord of 405 to 459 mm (15.9 to 18.1 in) while the female attains a wing chord of 428 to 496 mm (16.9 to 19.5 in). In males the tail may measure 204 to 244 mm (8.0 to 9.6 in) while the female may measure 223 to 262 mm (8.8 to 10.3 in). In tarsal length, males may measure 83 to 93 mm (3.3 to 3.7 in) while females attain 87 to 96 mm (3.4 to 3.8 in). In the nominate race, the culmen from the cere is 23.4 to 30 mm (0.92 to 1.18 in) in both sexes, with an average of 27.9 mm (1.10 in) in migrants at Eilat. Mature migrants in Eilat measured from 24.8 to 32.1 mm (0.98 to 1.26 in), averaging 27.8 mm (1.09 in), on the enlarged hallux-claw.

Paler individuals of the long-legged buzzard are typically reasonably distinctive but their highly variable plumage leads to mistaken identity. The main confusion is with the even more variable common buzzard (Buteo buteo ), principally of the steppe subspecies, which breeds and migrates in often similar areas. Steppe buzzards are told apart by various features of plumage, i.e. darker head and chest with a contrasting paler breast band, fully barred and darker uppertails, less distinct carpal patch both above and below, more contrasting wing lining with median coverts paler, with the greater covert darkest. Due to much variation in plumage, steppe buzzards often not reliably distinguished and in distant sightings best told apart by their smaller size and differing proportions. The steppe buzzard is distinctly smaller, of more compact build and possess a distinctly shorter wings and tail than nominate long-legged buzzards. Furthermore, the steppe buzzard has a more pronounced head but less protruding bill and flies with faster but stiffer and less flexible beats. Furthermore, steppe buzzards tend to fly with flatter wings in a glide and less pronounced dihederal without tips pointed up. Dark morphs of the respective species are so similar that they must be told by size, proportions and flight actions. Especially hard to tell apart from the steppe buzzard is the smaller North African subspecies. In Asia the long-legged buzzard is similar to the upland buzzard, which averages slightly bigger in size but is somewhat narrower winged. Typically the upland species has a large white patch on the hand above, with a uniform looking greyish white tail (with at most 2-3 dark bars only visible at close range), darker, more earthen brown on the breast and thighs and lacks the long-legged's typical warm, rufous tones. In dark morph upland buzzards, though they may manifest some darker ground colour on under secondaries and sometimes show pale U on breast but otherwise almost identical in appearance to dark morph long-legged buzzards. The only other Buteo that can be potentially confused with the long-legged buzzard is the migrant rough-legged buzzard (Buteo lagopus ) which is similar in size, proportions and flight behaviour, extending to hovering (however the rough-legged is marginally smaller in size with shorter legs and a shorter bill). The rough-legged buzzard should be told apart from the long-legged by having a distinctive white based tail with a broad dark subterminal band as well as fully feathered legs, Juvenile rough-legged buzzards lack the dark underwing diagonals of many juvenile long-legged buzzard. The long-legged buzzard is potentially confusable with other medium or large unrelated species of raptor from outside of the Buteo, including multiple species of small to mid-sized eagle and two species of honey buzzard. However, all of these usually tend to have a number of distinctive morphological, especially the proportion and shapes of their wings, head and tail and flight actions, as well as plumage features that tend to easily separate them from even the most similarly hued and sized of long-legged buzzards.

The long-legged buzzard inhabits arid areas of northern Africa, southeastern Europe, west and central Asia east to China, and down to as far as central India. The farthermost western part of their breeding range is in west Africa, in Western Sahara, extreme northern Mauritania, much of Morocco west to northern Algeria (spottily elsewhere in the nation), Tunisia and northern Libya (mainly northwestern parts). Long-legged buzzards occur accidentally in several other parts of Africa. In mainland Europe, they mainly nest in the southeastern region. Nesting long-legged buzzards have been known in eastern Hungary, central and eastern Ukraine, southern Moldova, southern and far eastern Romania, southern Serbia and more broadly in Bulgaria and somewhat so in northern Greece. Recent sightings indicate that there is a small population in the Apulian region of south-eastern Italy. Similarly, increasing records of long-legged buzzards are known in far southern Spain with the first nesting occurring in Gibraltar in 2009. The recent colonization Europe due to the climate in southern Europe becoming more suitable for this species. Vagrant accidental long-legged buzzards have been documented several times in many parts of Europe, including Finland, Denmark, the Netherlands, France, Poland, Czech Republic and Slovakia. Out of Europe in the eastern Mediterranean or Asia Minor, the long-legged buzzard is one of the most continuously found and abundant breeding resident raptors, being distributed throughout all of Turkey, Cyprus, Armenia, Georgia and Azerbaijan. The range continues into southwestern Russia up to about Saratov and Orenburg.

It is also widely and regularly distributed through much of the Middle East, residing almost throughout Syria, Lebanon, Israel, as well as the northern central parts of both Iraq and Iran. More uncommonly the breeding ranges extends into Oman, the United Arab Emirates, Yemen and Saudi Arabia. The range continues almost throughout Central Asia, residing in essentially all of Turkmenistan (including broadly along the Caspian Sea coast), Uzbekistan, all but the northern stretches of Kazakhstan, Tajikistan, Kyrgyzstan and northern and central Afghanistan. The breeding range discontinues in Northwestern China but isolated breeding was documented in the Kashmir region, perhaps straddling both Pakistan and India. During times of passage, long-legged buzzards have been seen more broadly in areas such as the Arabian Peninsula, southern Iraq, western China and northeast Africa, with those that breed in Europe, Russia and Central Asia often departing their breeding grounds for the winter. The wintering areas of migrating long-legged buzzards extend through much of lower Central Asia and the Indian subcontinent including southern Afghanistan, much of Pakistan and northern India through to Nepal, Bhutan and Bangladesh. Seldom vagrants have been recorded to as south as Sri Lanka, northern Burma and the Andaman Islands. Less consistent wintering populations may live from central Sudan and Eritrea, northern South Sudan, much of Ethiopia, into far northeastern Uganda and central Kenya, seldom into far northern Tanzania.

The long-legged buzzard inhabits open, uncultivated areas, with high bushes, trees, cliffs or hillocks are favoured as nesting areas as well as access to freshwater. The species normally lives in steppe, semi-desert and desert edge, barren rocky landscapes, dry shrubland and sometimes sea coasts. More irregularly, the species will adapt to woodland as long as plentiful openings are available. As a whole slightly hilly plains are ideal nesting areas. In a study in Iran, 41% of long-legged buzzards were on open plains with low vegetation, 29% on plains with somewhat taller vegetation, 12% were in mountain areas and 18% were in cultivated lands. While long-legged buzzards predominantly forage in wildlands, they are also adaptable to cultivations, pastures, village outskirts and sometimes even heavily farmed areas. Grasslands are often predominantly utilized during winter. Those wintering in the Indian subcontinent largely use similar arid open plains, semi-deserts and cultivated areas but perhaps surprisingly are considered a characteristic wintering raptor of dry mixed forests with open glades and barren hill slopes. In the Indian subcontinent, the species may often be seen using a variety of perches including bushes, hedges, Acacia nilotica, sand dunes, haystacks, mounds and power poles. The North African and Arabian race may reportedly show a strong preference for open wooded and/or rocky areas but has been reported in a similarly broad amount of habitats as the nominate subspecies. The species may occur from sea-level up to about 1,600 m (5,200 ft) in Europe, but in Asia uncommonly lives in mountains at elevations of up to 3,000 m (9,800 ft) or even 3,900 m (12,800 ft) with migrants recorded to 5,000 m (16,000 ft). Younger birds disperse north of breeding grounds and there are records from Northern Europe. The breeding population in Greece is around 60 pairs. Reforestation in the Judean Hills in Israel and the West Bank is increasing potential interspecific conflict for other raptors in the vicinity.

Habits and Lifestyle

While the North African race is largely sedentary some short-range dispersal, wandering occasionally to Iberia, while one moved to Senegal in October, rarely southward movements occur, such as to Burkina Faso and Lagos. The nominate race more or less residential in the southern part of the breeding range but almost wholly migratory in north and east of range. Autumn migration commences any time from late August to throughout September. Data from intermediate areas such as Lebanon indicates that autumn passage can extend occasionally into November. Unlike common buzzards, long-legged buzzards tend to migrate singly or in small flocks. Quite small numbers tend to be recorded at main migratory hawk-watches. For example, 1,816 at Suez from September to early November in 1981. In the south Red Sea coast at Bab-el-Mandeb the total number of long-legged buzzards is up to around 130 each autumn. The species normally reaches the Indian subcontinent by about September or October and leaves by about March. Corresponding arrival and departure dates as in the Indian subcontinent were documented for wintering long-legged buzzards in Korea. A majority of the species winter in the eastern Mediterranean, i.e. Greece, Asia Minor through Middle East and Arabia to southern Tibet and northern India, as well as elsewhere in Asia. Central Asian areas may show a mixture of migratory populations, staging grounds and some wintering buzzards. Moderate numbers of long-legged buzzards tend to be documented in Africa, mostly in the Nile Valley in Sudan and the species seldom ranges south of the Sahara but migrants have been documented in both west Africa and east Africa as vagrants. Spring returns flights occur from late February on for about a month and a half, peaking in the 2nd half of March with even fewer typically seen at major migratory sites than in the fall. For example, only about 105 are recorded throughout an average spring in Eilat. Breeding usually already commenced by March-mid April to May, even for birds breeding in the northerly part of the range.

Diet and Nutrition

Although frequently described as sluggish, the long-legged buzzard appears by most accounts to be a fairly active and powerful predator. This species often hunts by pounces on unwary prey from a variety of lookout perches. Long-legged buzzards, like many Buteo, regularly still-hunt, using tallish or high perch sites or mounds, spending long periods of time scanning the ground. Regular perch sites while hunting may include power poles, pylons, powerlines, boulders, rocky outcrops and dead and sometimes live trees. They also will watch for prey whilst standing on the ground, sometimes right by the entrance of a prey's burrow. No less often, they may hunt on the wing from hovering or active flight. During hunting on the wing they often hang in the air, at up to about 30 m (98 ft) above the ground, for sometimes several minutes, before dropping steepwise and making a short stoop. It is likely that the habitat being used and dictating availability of perches or sloping land from which to watch the ground dictate the variations in hunting modes seen in this species. Often the preferred hunting habitat is fairly open including upland steppe, arid semi-desert and cultivated fields. Occasionally they've been recorded in small towns as engaging in "stampeding" of pigeons resting on ledges, crevices and under the eaves of old buildings by suddenly flying up using the cover of the buildings and catching them as they rise. Long-legged buzzards are known to visit jungle or grass fires in order to capture displaced prey, often engaging in this along with other raptors. The long-legged buzzard has a fairly typical diet for a Buteo, having a generalist opportunistic diet overall, but with a preference for small mammal prey. Somewhat more so than many Buteo species, long-legged buzzards tends to take a great number of reptiles as prey, from fairly small to quite large sizes as well. More secondary prey types include birds, insects, other invertebrates and very rarely other types of vertebrates. The dietary biology of the long-legged buzzard is rather less well-documented than that of common buzzard, even in the European portion of their range, still nearly 200 prey species have been described for it. Staple prey, i.e. vertebrates, for long-legged buzzards taken generally fall in body mass between 20 g (0.71 oz) and 1,500 g (3.3 lb). Scavenging for carrion is not uncommon in long-legged buzzards, having been reported extensively on dog (Canis lupus familaris ) carcasses in Romania, however carrion seems to be only regularly ingested during the non-breeding season.

In one of the westernmost dietary studies, in the Ukraine, 450 mammalian prey remains found, with 565 total prey items (5.3% birds, 8.3% reptiles, 0.2% amphibians and 6.5% beetles). Main prey here were common vole (Microtus arvalis ), averaging an estimated 25 g (0.88 oz) and constituting 48.4% of the diet by number and 12.59% of the biomass and the greater mole-rat (Spalax microphthalmus ) and Podolsk mole-rat (Spalax zemni ), both averaging an estimated 215 g (7.6 oz) and collectively comprising 22% of the diet by number and 49.2% of the biomass. Other important prey were speckled ground squirrels (Spermophilus suslicus ) with the larger mammalian prey being very young European hare (Lepus europaeus ) at 500 g (1.1 lb) and adult European hamsters (Cricetus cricetus ) at 443 g (15.6 oz), on average. Different Ukrainian study found a predominance of greater mole-rats in the diet, with these constituting 44.5% of the diet by number, rodents altogether making up 77.5% of the foods. Meanwhile, the diet in this second Ukrainian study showed an unusual profusion of bird prey, making up 22.3%. The diet in the Hungarian Hortobágy Plains were found surprisingly among 94 prey items that 69.1% of the diet was beetles, with the European ground squirrel (Spermophilus citellus ) most frequent mammal at 19.1%. Elsewhere in Hungary, European ground squirrels were dominant in the diet in Dobruja while outside in Slovakia's Eastern Slovak Flat, the diet almost entirely based upon common vole but only reportedly when the voles were at the peak of their population cycle. Further study on the Great Hungarian Plains seems to reinforce the importance as elsewhere in eastern Europe of common voles and European hamsters in the diet of long-legged buzzards. In southeastern Bulgaria, among 189 prey items, Microtus species made up 22.2% of the diet, European ground squirrels were at 18.6%, brown rat (Rattus norvegicus ) at 10.6%, European water vole (Arvicola terrestris ) at 8.5% and Balkan green lizard (Lacerta trilineata ) at 4.76%. In Bulgaria, 68.8% of the diet was mammalian, 13.23% reptilian, 9% avian, 7.41% arthropods and other vertebrates the remaining balance, with prey varying in size from invertebrates weighing a fraction of a gram to mammals of up to 1.5 kg (3.3 lb) such as young European hare and non-native muskrats (Ondatra zibethicus ). Long-legged buzzards in northeastern Greece were found to be highly reliant on the European ground squirrel which comprised 21.2% of 268 prey items there. Most other prey were largely unidentified but included Orthoptera (10.8%) Scolopendra species (10.8%), snake sp. (8.2%), Lacerta sp. (7.83%) and common voles (7.46%).

The long-legged buzzard population in Georgia was found to live off of very small mammals. For instance, in Kvernaki Ridge, of 223 prey items, the main prey identified to species was social vole (Microtus socialis ) (at 27.35%) and house mouse (Mus musculus ) (at 7.17%), followed by assorted unidentified rodents (nearly 15% of diet) and Lacerta sp. (7.17%) and Caucasian agama (Paralaudakia caucasia ) (4.93%). In the uplands of Ninotsminda, 244 prey items were recorded to feed mostly on unidentified small rodents, especially voles, as well as larger European water vole (7.78%) and identified common voles (5.74%). In both study areas of Georgia, mammals comprised just over 59% of the total remains, unidentified insects comprised 18.4% and 22.5% of prey numbers, birds 6.3% and 13.5% of the diet and reptiles 16.2% and 4.52% of the diets, respectively. It appears in Armenia that their diet was very reptile based, mostly small to medium-sized lizards but even the remains of a Greek tortoise (Testudo graeca ) were reported. On the isle of Cyprus, 559 prey total prey items were found by combination of observation, prey remains and pellets. The main prey here by far were black rats (Rattus rattus ) at 46.3% of the diet and starred agama (Stellagama stellio ) at 30.4%. Overall in Cyprus, 49.1% of the diet was mammalian, reptiles more than 40%. Young rats, agamas and Schneider's skinks (Eumeces schneiderii ) were well represented in the Cyprus diet, rendering an estimated rough two-thirds of the diet to consist of small prey weighing 100 g (3.5 oz) or less. However, a not inconsiderable amount of prey weighing in the range of 500 g (1.1 lb) were taken including young European hares, large whipsnake (Dolichophis caspius ) (at 5% of the diet by number) and birds such as chukar (Alectoris chukar ) and common wood pigeon (Columbus palumbus ).

Accompanying food studies of the long-legged buzzards were conducted in the Israeli Judean Hills. Among 1239 total prey items from 32 nests here, the primary prey appeared to be Schneider's skinks at 16.3% and starred agamas at 14.6%, with an old study finding rock doves or feral pigeons (Columbus livia ) the most significant at 19.6% of 561 prey items (pigeons were 10.7% amongst the 1239 prey items). Overall the Judean Hills long-legged buzzards preferred reptiles, at 47.2% of the foods, and birds, at 32.2%, rather strongly over mammals, 18.3%, which is not unexpected in the region's semi-desert environment. The predominant prey in Jordan was reportedly the fat sand rat (Psammomys obsesus ) followed by again the starred agama and generally appeared not dissimilar from the diet of the species on Cyprus. On the Arabian Peninsula, long-legged buzzards were reported to feed mostly on the largish Uromastyx lizards, but also took hares, birds, and carrion. In northern Iran's Khar Turan National Park, 34 remains seemed to be predominantly represented by unidentified hares, occasionally supplemented by birds, tortoises and smaller mammals like Meriones and Gerbillus species. In southwestern Iran, 100 estimated prey items found by combination of prey remains, pellets and video recordings. The main prey were Caucasian squirrels (Sciurus anomalus ) at 29.85% by number, 39.4% by biomass (with an estimated mean mass of 300 g (11 oz) and mature adult agamas such as brilliant ground agamas (Trapelus agilis ), large-scaled agama (Laudakia nupta ) (both estimated at 300 g (11 oz) when taken and small-scaled agama (Paralaudakia microlepis ), these three comprising 30.3% of the diet collectively and 36.5% of the prey biomass. Several snakes like spotted whipsnakes (Hemorrhois ravergieri ) were also taken frequently here.

While the diet is reasonably well studied in the European, eastern Mediterranean and Middle Eastern areas, farther east the diet is largely incidentally known, from secondary observations and rarely quantitatively analyzed (while the North African populations are almost entirely unknown in terms of dietary biology). In the East Kazakhstan Region, two long-legged buzzard nests were found to primarily contain the remains of contained the remains of Tamarisk gerbil (Meriones tamariscinus ) and red-cheeked ground squirrels (Spermiphilus erythrogenys ). A study in the Kalmykia region of Russia found that about 100 prey items of long-legged buzzards consisted of by diverse prey and less based in small mammals or lizards than other regions. The most frequent identified prey here were unidentified larks, at 18% of the diet by number and 4.7% by biomass, while very young juvenile European hare, at estimated mean of 400 g (14 oz) body mass, were second in number, at 9%, and primary in biomass at 21.8%. Other significant prey here were social voles, at 9% by number as well, and adult rooks (Corvus frugilegus ), at a mean mass of 460 g (1.01 lb) comprising 15.7% of the biomass. In northeastern China, the diet was fairly well studied, albeit in a somewhat small study. Of 50 prey items, here great gerbils (Rhombomys opimus ) led the diet at 48%, followed by Tartar sand boa (Eryx miliaris ) (18%), cape hare (Lepus capensis ) (6%), goitered gazelle (Gazella subgutturosa ) (6%) (likely but not certainly taken to the nest as carrion) and Mongolian finch (Bucanetes mongolicus ) (6%). Overall mammals made 60% of the diet, reptiles 22% and birds 18%. The diet in the Indian subcontinent is quite diverse, with prey often observed to be taken consisting of small mammals, being up to 85% of the diet, with primary prey often being Indian desert jird (Meriones hurrianae ) in arid areas and voles and pikas in highland areas. Lizards are significant, especially Indian spiny-tailed lizard (Saara hardwickii ) and agamas, as well as snakes and various other prey.

Mating Habits

The long-legged buzzard is, as is typical for Buteo and accipitrids, usually rather solitary outside of the pair bond. However, occasionally forms very loose breeding groups, at times several as close as 300 m (980 ft) or in the same crag. It is also slightly gregarious sometimes in passage in small groups, rarely traveling in large flocks. The long-legged buzzard’s aerial display similar but less well documented than that of the common buzzard. They tend to engage in mutual high circling, with both sexes diving at each other. Additionally, an impressive sky dance is sometimes undertaken by the male in which he circles before plunging on part closed wings, swooping up again, after which he may engage in tilting or even looping the loop at the zenith, drops nearly vertically, repeating dance one or more times. Territories are fairly large for long-legged buzzards. In Ukraine, there was an estimated per pair occupancy of about 120 km2 (46 sq mi) while in Kazakhstan, in an area of 100 km2 (39 sq mi), there an estimated mean of 2.8 nesting pairs.

The breeding season of the long-legged buzzard can fall at variable times of the years. In Europe, it tends to breed from March to July. Similarly phenology of breeding is reported in Armenia and even in Iraq. In the United Arab Emirates, a nest with eggs which must have been laid in December was reported, with pair occupancy lasting to at least March. In Morocco, nuptial displays begin in January and February, peaking in March, with egg laying usually from March to April in the northern part of the country and from February to April in southern part. Elsewhere in North Africa, breeding seems to fall somewhat earlier from February to March, with possibly fledging completed by the month of May. The nesting period in Pakistan is about March to July, but records of eggs as late as June may refer to second or replacement clutches being laid. The nest is a large pile of sticks and branches, typically lined with green leaves, twigs, straw and wool. Nests are fairly large structures, averaging around 71 to 99 cm (28 to 39 in) in diameter, as in Bulgaria and Kazakhstan, respectively, but could easily exceed 1 m (3.3 ft) across in some cases. The average depth was 20 and 49 cm (7.9 and 19.3 in), ranging in Bulgaria and Kazakhstan from 15 to 100 cm (5.9 to 39.4 in) in depth.

Often this species nests are located on a cliff ledge, crag or low rocks, often in fairly shaded relative to the often sunny environs. In Kazakhstan, more than 75% of 53 nests were on such ledges or in granite niches, with a further 11% on power poles, 8% in trees and 4% on high hills less frequently nest ground, in a tree or steep slope or old large bird nest. In Cyprus, of 22 nests, only 1 was in a tree, while the rest were a variety of cliffs from sea cliffs to mountainous areas of around 1,100 m (3,600 ft) elevation. All known nests in northwestern China as well as in southwestern Iran were located on cliffs. In Bulgaria, in the absence of natural rocks, the long-legged buzzards largely adapted to nesting alongside manmade quarries rather than use trees. Nesting locations were exceptional then in the Ukraine where most (85.7%) were built in oak trees, with one additionally placed in a pear tree. Data from the Volga region of Russia also suggests that tree nesting is common for the species there, especially in Malus apple trees. Additionally, the few known nests from Pakistan have appear to be located in trees such as Abies firs or junipers. Some nests along the perimeter of old buildings have been documented as well. At times the long-legged buzzard will use the old nest of another species, apparently largely ravens such as common ravens (Corvus corax ) or brown-necked raven (Corvus ruficollis ). Nests are frequently reused in subsequent years and added to over time.

The long-legged buzzard may lay a variably sized clutch. Typically 2 to 4 eggs are laid but from 1 to 6 egg clutches have been documented. The average clutch size in the Ukraine was 2.7, in a sample of 8. The same clutch size mean was reported in Cyprus as well. The average clutch size in North Africa was reported (in a sample of 57) as 2.54. The clutch size in northwestern Iran averaged 3. In northwestern China, the mean clutch size was 3.3. The eggs are slightly rough, oval and largely whitish with a yellowish tint and a few wart like projections, with indistinct gray-brown to reddish brown markings, which tend to fade at the pointer tip of the oval. The average egg sizes in the Ukraine, Armenia and northwestern China were 59.5 mm × 46.9 mm (2.34 in × 1.85 in), 60.3 mm × 47.2 mm (2.37 in × 1.86 in) and 56 mm × 43 mm (2.2 in × 1.7 in), respectively. Egg heights ranged from 53 to 63 mm (2.1 to 2.5 in) and diameter ranged from 42 to 49.5 mm (1.65 to 1.95 in), while in Armenia eggs weighed 72.9 g (2.57 oz) on average and in China they weighed 68.2 g (2.41 oz). Incubation appears to last for about 28 to 30 days.

Upon hatching, the young are expectedly semi-altricial. The brood size averages about 2.3. The chicks initially have fine white down at first and then develop a second down coat with white to creamy white. The chicks are brooded considerably, especially by their mother for about 30 days, after which she may resume hunting. Fledgling of the chicks may occur at between 40 and 46 days of age for the young buzzards. The dependence period after they leave the nest can be relatively prolonged for a temperate-zone raptor, reaching perhaps a month in total. Breeding success rates are relatively quite poorly known in long-legged buzzards, with many sources failing to find extensive data on this topic. Data from Cyprus shows the nesting success varying greatly, perhaps based on food supplies, with an annual mean success rate varying from 46% to 93%. In northwestern China, the mean number of fledglings per nest was 0.7 while the mean fledged from successful nests was 1.4. The maximum estimated mean productivity per pair in Israel was about 0.96.

Population number

Some declines have been reported in western Russia and generally the long-legged buzzard may be somewhat less numerous than they once were in the more western parts of the range. On the other hand, since the 1990s, there have been recent increases reported in Europe, mainly Bulgaria, where expanding population and post-breeding dispersals have enlarged their range in Hungarian steppes. In 1990s, the estimated population in the Western Palearctic was between 5000 and 15,000 pairs while by 2015 the estimated population where was 11,800-19,200 pairs breeding pairs. The following estimates show from the smaller numbers of the 1990s to the generally higher estimated numbers by 2015. There are an estimated 800-1500 pairs nesting in western Russia, 200-750 pairs occurring in Bulgaria and about 60-300 pairs in Greece and 50 pairs in the Ukraine, with fewer in Albania and a few other countries. Europe contains less than a quarter of the global population and the declines from historic numbers were still over 30%, so the long-legged buzzard is considered locally a Vulnerable species in Europe. Furthermore, about 500 pairs are estimated to nest in Israel, as recorded after slight population depletions due largely to pesticide use in the 1950s. The Turkish population is ample at 1000-10,000 pairs, probably 3000-6000; with about 1000-2500 in Azerbaijan. Additionally, numbers are considered unchanged in Armenia. There are less well known populations and trends in North Africa, with perhaps 400 pairs in Tunisia, 1000 or more pairs in Morocco. A small number nest in the Arabian Peninsula. Arabia has thought to experience a 5% decline in long-legged buzzard populations, perhaps due to overly extensive conversion of habitat to farmland and stone quarries. Saudi Arabia holds about 600 pairs, Oman and Yemen both about 100 pairs and the United Arab Emirates about 5 pairs. Fewer figures still are available from Asia, where the species is considered uncommon to rare in Pakistan, slightly more common in Kashmir and variously rare to uncommon in northwestern China and Turkmenia. Good habitat and strong circumstantial evidence of strong continuous breeding pairs in Central Asia has led to a projected fairly ample but poorly documented population in this region.
