Theshikra(Tachyspiza badia) is a smallbird of preyin the familyAccipitridaefound widely distributed in Asia and Africa where it is also called thelittle banded goshawk.The African forms may represent a separate species but have usually been considered as subspecies of the shikra. The shikra is very similar in appearance, as well as behavior, at least to some degree, to other species including theChinese sparrowhawk(Accipiter soloensis),Eurasian goshawk(Astur gentilis) andEurasian sparrowhawk(Accipiter nisus). They have a sharp two note call and have the typical flap and glide flight. Their calls are imitated bydrongosand thecommon hawk-cuckooresembles it in plumage. This species was formerly placed in the genusAccipiter.
Taxonomy
[edit]The shikra wasformally describedin 1788/1789 by the German naturalistJohann Friedrich Gmelinin his revised and expanded edition ofCarl Linnaeus'sSystema Naturae.He placed it with the eagles, hawks and relatives in thegenusFalcoand coined thebinomial nameFalco badius.[2]Gmelin's description was based on the "brown hawk" from Ceylon that had been described and illustrated in 1776 by the English naturalistPeter Brown.[3]The shikra was formerly placed in the large and diverse genusAccipiter.In 2024 a comprehensivemolecular phylogeneticstudy of the Accipitridae confirmed earlier work that had shown that the genus waspolyphyletic.[4][5]To resolve the non-monophyly,Accipiterwas divided into six genera. The genusTachyspizawas resurrected to accommodate the shikra together with 26 other species that had previously been placed inAccipiter.The resurrected genus had been introduced in 1844 by the German naturalistJohann Jakob Kaup.[6]The wordTachyspizacombines theAncient Greekταχυς (takhus) meaning "fast" with σπιζιας (spizias) meaning "hawk".[7]The specific epithetbadiaisLatinmeaning "chestnut-coloured" or "brown".[8]
Six subspecies are recognised:[6]
- T. b. sphenura(Rüppell,1836) – Senegal and Gambia to southwest Arabia south to north Tanzania and north DR Congo
- T. b. polyzonoides(Smith, A,1838) – south DR Congo and south Tanzania to South Africa
- T. b. cenchroides(Severtsov,1873) – Caucasus to central Asia and northwest India
- T. b. dussumieri(Temminck,1824) – central India and Bangladesh
- T. b. poliopsis(Hume,1874) – north India to south China, Indochina and north Sumatra
- T. b. badia(Gmelin, JF,1788) – southwest India and Sri Lanka

The shikra is a small raptor (26–30 cm long) and like most otherTachyspizahawks, this species has short rounded wings and a narrow and somewhat long tail. Adults are whitish on the underside with fine rufous bars while the upperparts are grey. The lower belly is less barred and the thighs are whitish. Males have a red iris while the females have a less red (yellowish orange) iris and brownish upperparts apart from heavier barring on the underparts. The females are slightly larger. The mesial stripe on the throat is dark but narrow. In flight the male seen from below shows a light wing lining (underwing coverts) and has blackish wing tips. When seen from above the tail bands are faintly marked on the lateral tail feathers and not as strongly marked as in theEurasian sparrowhawk.The central tail feathers are unbanded and only have a dark terminal band.[9]Juveniles have dark streaks and spots on the upper breast and the wing is narrowly barred while the tail has dark but narrow bands. A post juvenile transitional plumage is found with very strong barring on the contour feathers of the underside.[10]The call ispee-wee,the first note being higher and the second being longer. In flight the calls are shorter and sharperkik-ki... kik-ki.TheChinese sparrowhawkis somewhat similar in appearance but has swollen bright orange ceres and yellow legs with the wing tips entirely black.[11][12]
Subspeciescenchroidesis larger and paler and found in Turkestan, Afghanistan and eastern Iran. The Indian populationdussumieriis resident on the plains and lower hills (up to 1400 m in the Himalayas). The nominate form is found in Sri Lanka and has somewhat darker grey upperparts. The Burmese shikraA. b. poliopsismay represent a distinct species. The population on the island ofCar Nicobar,earlier treated as a subspeciesbutleri[13]and that onKatchal Island,obsoletusare now treated as a sub-species within a full species, theNicobar sparrowhawk(Tachyspiza butleri).[11][14]The west African populationT. b. sphenurusis migratory while the southern AfricanT. b. polyzonoidesis more nomadic in its movements. In Asia onlyT. b. cenchroidesis migratory.[10]
Behaviour and ecology
[edit]The shikra is found in a range of habitats including forests, farmland and urban areas. They are usually seen singly or in pairs. The flight is typical with flaps and glides. During the breeding season pairs will soar on thermals and stoop at each other. Their flight usually draws alarms among smaller birds and squirrels. They feed on rodents (includingMeriones hurrianae[15]), squirrels, small birds, small reptiles (mainly lizards but sometimes small snakes[16]) and insects.[14]Small birds usually dive through foliage to avoid a shikra and a Small Blue Kingfisher has been observed diving into water to escape. Babblers have been observed to rally together to drive away a shikra.[17]They will descend to the ground to feast on emerging winged termites,[18]hunt at dusk for small bats[19](such asCynopterus sphinx[20][21]) and in rare instances they may even resort to feed on carrion.[22]In one instance a male was found feeding on a dead chick at the nest.[23]Their calls are mimicked bydrongosand this behaviour is thought to aid in stealing food by alarming other birds that the drongos associate with.[24][25]
Breeding
[edit]![](https://upload.wikimedia.org/wikipedia/commons/thumb/9/94/Accipiter_badius_MHNT.ZOO.2010.11.94.1.jpg/200px-Accipiter_badius_MHNT.ZOO.2010.11.94.1.jpg)
The breeding season in India is in summer from March to June. The nest is a platform similar to that of crows lined with grass. Both sexes help build the nest, twigs being carried in their feet.[26]Like crows, they may also make use of metal wires.[27]The usual clutch is 3 to 4 eggs (when eggs are removed they lay replacements and one observer noted that they could lay as many as 7 in a season[28]) which are pale bluish grey stippled on the broad end in black. The incubation period is 18 to 21 days.[14]
In culture
[edit]The shikra was a favourite amongfalconersin India and Pakistan due to the ease with which it could be trained and was frequently used to procure food for the more prized falcons. They were noted for their pluck and ability to take much larger birds including partridges, crows and even young peafowl.[14][29][30]The wordshikraorshikarameans hunter in the Hindi language (the male was calledchipakorchipkabased on call[31]) The word Shikra is borrowed from the Urdu word (شِـكْـره) which is derived from the word shikari (شِكارى) meaning hunter.[32]
The word is also used in the French nameLe Chicquerawhich was however given to thered-necked falconby Levaillant in 1799.[33][34][35]
Famous Punjabi poetShiv Kumar Batalviwrote a poem called "Main Ik Shikra Yaar Banaya" about a lost love wherein he compares her to a shikra.[36][37]
