Taxonomy and systematics The name commemorates the British naturalist Allan Octavian Hume who described the species. The alternate name short-toed lark may also be used for three other species in the genus ''Calandrella''. The alternate name lesser short-toed lark should not be confused with the species of the same name, ''Alaudala rufescens''. Other alternate names for Hume's short-toed lark include Hume's lark and Karakoram short-toed lark. Subspecies Two subspecies are recognized: * ''C. a. acutirostris'' - Hume, 1873: Found from north-eastern Iran and eastern Kazakhstan to western China * Tibet short-toed lark (''C. a. tibetana'') - Brooks, WE, 1880: Originally described as a separate species. Found from north-eastern Pakistan to Tibetan Plateau Description Hume's short-toed lark is similar in size an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Supercilium
The supercilium is a plumage feature found on the heads of some bird species. It is a stripe which runs from the base of the bird's beak above its eye, finishing somewhere towards the rear of the bird's head.Dunn and Alderfer (2006), p. 10 Also known as an "eyebrow", it is distinct from the eyestripe, which is a line that runs across the lores, and continues behind the eye. Where a stripe is present only above the lores, and does not continue behind the eye, it is called a supraloral stripe or simply supraloral. On most species which display a supercilium, it is paler than the adjacent feather tracts. The colour, shape or other features of the supercilium can be useful in bird identification. For example, the supercilium of the dusky warbler, an Old World warbler species, can be used to distinguish it from the very similar Radde's warbler. The dusky warbler's supercilium is sharply demarcated, whitish and narrow in front of the eye, becoming broader and more buffy towards the ...

Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the Common ostrich, ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species.

Birds Of The Himalayas
The ecology of the Himalayas varies with climate, rainfall, altitude, and soils. The climate ranges from tropical at the base of the mountains to permanent ice and snow at the highest elevations. The amount of yearly rainfall increases from west to east along the southern front of the range. This diversity of climate, altitude, rainfall and soil conditions supports a variety of distinct plant and animal species, such as the Nepal gray langur (''Semnopithecus schistaceus'') Lowland forests On the Indo-Gangetic plain at the base of the mountains, an alluvial plain drained by the Indus and Ganges-Brahmaputra river systems, vegetation varies from west to east with rainfall. The deserts and xeric shrublands, xeric Northwestern thorn scrub forests occupy the plains of Punjab, Pakistan, Pakistani and the Punjab, India, Indian Punjab.

Calandrella
''Calandrella'' is a genus of larks in the family Alaudidae. Taxonomy and systematics The genus ''Calandrella'' was established by the German naturalist Johann Jakob Kaup in 1829 with the greater short-toed lark as the type species. The genus name is a diminutive of Ancient Greek ''kalandros'', the calandra lark. Four of the species in the genus use the shortened name of short-toed lark as an alternate name. Extant species Six species are recognized in the genus: Extinct species At least one fossil species is included in this genus: * †''Calandrella gali'' (late Miocene of Polgardi, Hungary) Former species Some authorities have classified the following species as belonging to the genus ''Calandrella'': * Buckley's lark (as ''Calandrella buckleyi'') * Obbia lark (as ''Calandrella obbiensis'') * Sclater's lark (as ''Calandrella sclateri'') * Stark's lark (as ''Calandrella starki'') * Masked lark (as ''Calandrella personata'') * Botha's lark (as ''Calandrella fringillaris'') * ...

Greater Short-toed Lark
The greater short-toed lark (''Calandrella brachydactyla'') is a small passerine bird. The current scientific name is from Ancient Greek. The genus name, ''Calandrella'', is a diminutive of ''kalandros'', the calandra lark, and ''brachydactila'' is from ''brakhus'', "short", and ''daktulos'', "toe". It breeds in southern Europe, north-west Africa, and across the Palearctic from Turkey and southern Russia to Mongolia. During migration they form large, tight flocks that move in unison; at other times they form loose flocks. Taxonomy and systematics The greater short-toed lark was described by the German naturalist Johann Leisler in 1814 and given the binomial name ''Alauda brachydactila''. This lark is now placed in the genus ''Calandrella'' that was established by another German naturalist, Johann Jakob Kaup, in 1829. The specific name ''brachydactyla'' is from the Ancient Greek βραχυδακτυλος ''brakhudaktulos'' "short-toed" from ''brakhus'' "short" and ''daktul ...
