Ferguson-Lees, J., and D. A. Christie (2001). Raptors of the World. Christopher Helm, London, UK.
). Distinctive black shoulder patches evident at all ages, when perched
or in buoyant, gull-like flight; often hovers, and when perched pumps tail up and down
. Only slight size difference between sexes, with female just 3% larger and up to 19% heavier (1
Ferguson-Lees, J., and D. A. Christie (2001). Raptors of the World. Christopher Helm, London, UK.
). Pale primary-coverts on underwing separate from congeners. Juvenile browner, eye pale yellow not red. Races separated on size and intensity of plumage colour: wahgiensis smallest and has grey wash over sides of breast and blacker underside to primaries (like nominate); hypoleucus largest and longer-tailed, has larger white forehead patch, white breast-sides and flanks, underside to primaries paler and greyer (sometimes even whitish) and primary-coverts sometimes have larger, dark grey spots near tips; nominate and <em>vociferus</em>
are similar in having small white forehead patch, breast-sides and flanks pale grey to off-white, blackish underside to primaries and primary-coverts have only greyish flecks at tips, but vociferus usually has a darker underside to the secondaries (1

Systematics History
Editor's Note: This article requires further editing work to merge existing content into the appropriate Subspecies sections. Please bear with us while this update takes place.
Traditionally thought to form a species-group with E. axillaris and E. leucurus; all three sometimes considered conspecific, but differ variously in plumage, morphology and behaviour. Form hypoleucus has been treated as separate species; vociferus sometimes included in nominate (2
Ferguson-Lees, J., and D. A. Christie (2001). Raptors of the World. Christopher Helm, London, UK.
). Race wahgiensis sometimes included in hypoleucus. Proposed races sumatranus (from Sumatra) and intermedius (Java) doubtfully separable from hypoleucus. Four subspecies normally recognized.
SW France, N and W Iberian Peninsula, most of Africa and SW Arabia.

Editor's Note: Additional distribution information for this taxon can be found in the 'Subspecies' article above. In the future we will develop a range-wide distribution article.
Habitat
Open savanna grasslands with scattered bushes and small trees; extends into arid steppe, desert or clearings in dense woodland, wherever prey is abundant. Presence of expanding population in Spain strongly associated with grazed, cultivated parklands called dehesas (6
Balbontín, J., Negro, J.J., Sarasola, J.H., Ferrero, J.J. and Rivera, D. (2008). Land-use changes may explain the recent range expansion of the Black-shouldered Kite Elanus caeruleus in southern Europe Ibis. 150(4): 707–716.
). Usually recorded from sea-level to 750 m in Europe, but to c. 2020 m in S Asia (7
Choudhury, A. (2001). Some bird records from Nagaland, north-east India. Forktail 17:91–103.
), 3000 m in Africa (1
Ferguson-Lees, J., and D. A. Christie (2001). Raptors of the World. Christopher Helm, London, UK.
), and 2400 m in SW Arabia (8
Jennings, M. C. (2010). Atlas of the Breeding Birds of Arabia. Fauna of Arabia 25. King Abdulaziz City for Science and Technology, Saudi Wildlife Commission and Senckenberg Forschungsinstitut und Naturmuseum, Riyadh, Saudi Arabia and Frankfurt, Germany.
). Outside breeding season, up to 500 birds may roost communally in trees or reedbeds, spreading out by day to individual hunting territories.
Movement
Nomadic, ranging widely throughout its extensive range, in search of conditions supporting abundant prey; often travels long distances, and even crosses equator, e.g. from Transvaal (South Africa) to Malawi (9
Dowsett-Lemaire, F. (2006). A Contribution to the Ornithology of Malawi. Tauraco Research Report 8. Tauraco Press, Liège, Belgium.
) and Uganda. Considerable monthly turnover, even in local populations which appear to be stable and sedentary, usually with males arriving first and remaining longest on territories, and females wandering in search of mates and nesting opportunities. Post-breeding dispersal is recorded in Iberian Peninsula, where the species is most widely distributed in winter although still concentrated in W & SW; a few individuals cross the Strait of Gibraltar (10
de Juana, E., and E. Garcia (2015). The Birds of the Iberian Peninsula. Bloomsbury, London, UK.
). Vagrant N to Belgium (11

Ferguson-Lees, J., and D. A. Christie (2001). Raptors of the World. Christopher Helm, London, UK.
); records in France, away from tiny breeding range (centred on Pyrénées-Atlantiques and Landes), have increased in recent decades presumably as a result of population growth in Iberia (15

).
Diet and Foraging
Primarily rodents
of 40–90 g (exceptionally up to 164 g) (1
Ferguson-Lees, J., and D. A. Christie (2001). Raptors of the World. Christopher Helm, London, UK.
); shrews, bats, small birds (including doves, larks, pipits and emberizids) (1
Ferguson-Lees, J., and D. A. Christie (2001). Raptors of the World. Christopher Helm, London, UK.
), reptiles and insects also predominate at times. S African study found that just three rodent species comprised 98% of diet and that breeding birds selected larger prey species that immatures and non-breeders; furthermore, larger prey became more important as breeding cycle progressed (20
Slotow, R. and Perrin, M.R. (1994). Large prey as a qualitative stimulus to breeding in small raptors. Journal of Ornithology. 135(1): 6.
). Israeli breeders apparently heavily dependent on social voles (Microtus socialis guentheri) (3
Perlman, Y. and Israeli, N. (2013). Black-shouldered Kite Elanus caeruleus breeding in Israel. Sandgrouse. 35(1): 25–27.
). In Sabah, Borneo, analysis of 597 pellets confirmed the following remains: Polynesian rat (Rattus exulans, 67%), short-horned grasshopper (Valanga nigricornis, 23%), unidentified small rodents (5%), Whitehead’s spiny rat (Maxomys whiteheadi, 2·7%), Asiatic rhinoceros beetle (Oryctes rhinoceros, 1·3%), south-east Asian white-toothed shrew (Crocidura fuliginosa, 0·8%) and White-breasted Waterhen (Amaurornis phoenicurus, 0·2%), while an additional 100 carcasses also included Malaysian house rats (Rattus rattus diardii, 61%) and common sun skink (Eutropis multifasciata, 6%) (21

). Hunts from perch (tree, pole or wire) (1
Ferguson-Lees, J., and D. A. Christie (2001). Raptors of the World. Christopher Helm, London, UK.
) or hovers, usually making a slow descent in stages, with wings held in high dihedral above the back and feet extended below, and ending with a fast plunge into ground cover. Hovers in still or windy conditions. Sometimes engages in fast gliding flight low above ground, and also hawks locusts and other winged insects in flight (1
Ferguson-Lees, J., and D. A. Christie (2001). Raptors of the World. Christopher Helm, London, UK.
). Often crepuscular in hunting. Frequently consumes prey in flight, even including small mammals (1
Ferguson-Lees, J., and D. A. Christie (2001). Raptors of the World. Christopher Helm, London, UK.
).
Sounds and Vocal Behavior
Generally, vocalizations are high-pitched and weak, and given most frequently in courtship and around nest, e.g. a piping “pee-oo” in contact between pair and also by male to advertise territory; also harsher “kree-uk” in aggression and a whistled scream in alarm (1
Ferguson-Lees, J., and D. A. Christie (2001). Raptors of the World. Christopher Helm, London, UK.
).
Breeding
In Spain, copulation begins up to 44 days before onset of laying and may continue until 66 days after laying (22
Ferrero, J.J., Grande, J.M. and Negro, J.J. (2003). Copulation behavior of a potentially double-brooded bird of prey, the Black-winged Kite (Elanus caeruleus). Journal of Raptor Research. 37(1): 1–7.
). Peak laying at start or end of summer or wet season in sub-Saharan Africa and India, but recorded in all months in opportunistic reaction to rodent availability, especially that of larger species; more seasonal in N Africa and S Europe, Feb–Apr, with young in nest until at least mid May (23
Moali, A. and B. Gaci (1992). Les rapaces diurnes nicheurs en Kabylie (Algérie). Alauda 60(3):164–169.

). One of few species to prosper in areas of agriculture, bush clearing and heavy grazing, e.g. along R Nile; currently in expansion in several parts of range, e.g. in Egypt, where historically widespread and common, declined during mid-20th century, but started increasing again in 1980s (41
Meininger, P.L. (1991). Range extension of Black-winged Kite Elanus caeruleus in northern Egypt. Sandgrouse. 13: 98–101.
). Recent spate of records of race vociferus in Israel culminated in five pairs breeding in 2011–2012 (3

). Mobility and reproductive biology ensure optimum use of resources, repeated colonization of ephemeral or marginal habitats, high fecundity and maintenance of large megapopulations. In South Africa, prone to being killed by vehicles, presumably because of high foraging activity on or adjacent to roads (47

). Affected locally by rodenticides.
Relative abundance is depicted for each season along a color gradient from a light color indicating lower relative abundance to a dark color indicating a higher relative abundance. Relative abundance is the estimated average count of individuals detected by an eBirder during a 1 hour, 1 kilometer traveling checklist at the optimal time of day for each species.
