The grey francolin (Ortygornis pondicerianus) is a species of francolin found in the plains and drier parts of the Indian subcontinent and Iran. This species was formerly also called the grey partridge, not to be confused with the European grey partridge. They are mainly ground-living birds and are found in open cultivated lands as well as scrub forest and their local name of teetar is based on their calls, a loud and repeated Ka-tee-tar...tee-tar which is produced by one or more birds. The term teetar can also refer to other partridges and quails. During the breeding season calling males attract challengers, and decoys were used to trap these birds especially for fighting.
The grey francolin was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae . He placed it with all the grouse like birds in the genus Tetrao and coined the binomial name Tetrao pondicerianus. [2] Gmelin based his description on "Le perdix de Pondichéry" that had been described in 1782 by the French naturalist Pierre Sonnerat in his Voyage aux Indes orientales et a la Chine. [3] The grey francolin was formerly placed in the genus Francolinus . Based on a phylogenetic study published in 2019 the grey francolin, together with the crested francolin and swamp francolin, were moved to the resurrected genus Ortygornis that had been introduced in 1852 by the German naturalist Ludwig Reichenbach. [4] [5] [6] The genus name combines the Ancient Greek ortux meaning "quail" with ornis meaning "bird". The specific epithet pondicerianus is from the toponym Pondicherry, a town in southeast India. [7]
Three subspecies are recognised: [6]
This bird is a medium-sized francolin, with males averaging 11.6–13.4 in (29–34 cm) and females averaging 10.2–11.9 in (26–30 cm). The males weigh 9–12 oz (260–340 g) whereas the weight of the females is 7–11 oz (200–310 g). [9] The francolin is barred throughout and the face is pale with a thin black border to the pale throat. The only similar species is the painted francolin, which has a rufous vent. The male can have up to two spurs on the legs while females usually lack them. Subspecies mecranensis is palest and found in arid North-Western India, Eastern Pakistan and Southern Iran. Subspecies interpositus is darker and intermediate found in northern India. The nominate race in the southern peninsula of India has populations with a darker rufous throat, supercilium and is richer brown. They are weak fliers and fly short distances, escaping into undergrowth after a few spurts of flight. [10] In flight it shows a chestnut tail and dark primaries. [11] The race in Sri Lanka is sometimes given the name ceylonensis or considered as belonging to the nominate. [12] [13] [14]
The grey francolin is normally found foraging on bare or low grass covered ground in scrub and open country, and is rarely found above an altitude of 500 m above sea level in India, and 1200 m in Pakistan. The distribution is south of the foothills of the Himalayas westwards to the Indus Valley and eastwards to Bengal. It is also found in north-western Sri Lanka. Introduced populations are found in the Andaman and Chagos Islands. [11] [15] They have been introduced to Nevada in the United States of America and Hawaii, along with several other species of francolin. [16] [17]
The loud calls of the birds are commonly heard early in the mornings. Pairs of birds will sometimes engage in a duet. The female call is a tee...tee...tee repeated and sometimes a kila..kila..kila and the challenge call kateela..kateela..kateela is a duet. [18] They are usually seen in small groups. [11]
The main breeding season is April to September and the nest is a hidden scrape on the ground. [11] The nest may sometimes be made above ground level in a niche in a wall or rock. [19] The clutch is six to eight eggs, but larger clutches, potentially reflecting intraspecific brood parasitism, have been noted. [20] [21] [22]
Food includes seeds, grains as well as insects, particularly termites [20] and beetles (especially Tenebrionidae and Carabidae). [23] They may occasionally take larger prey such as snakes. [24] [25]
They roost in groups in low thorny trees. [26]
Several species of feather mites, helminth and blood parasites have been described from the species. [27] [28] [29] [30] [31]
They are hunted in much of their range using low nets and easily caught using calling decoy birds. [12]
The species has long been domesticated in areas of northern Indian subcontinent where it is used for fighting. [33] [34] The domesticated birds can be large at around 500-600g, compared to 250g for wild birds. They are usually carefully reared by hand and become as tame and confiding as a pet dog. [20]
Several authors have described the running of the birds as being particularly graceful:
They run very swiftly and gracefully; they seem to glide rather than run, and the native lover can pay no higher compliment to his mistress than to liken her gait to that of the Partridge.
John Lockwood Kipling, Rudyard Kipling's father, wrote of this and other partridges such as the chukar partridge:
The creature follows its master with a rapid and pretty gait that suggests a graceful girl tripping along with a full skirt well held up. The Indian lover can pay his sweetheart no higher compliment than to say she runs like a partridge. In poetry the semblance is one of best hackneyed of Indian metaphors. In poetry, too, the partridge is associated with the moon, and, like the lotus, is supposed to be perpetually longing for it, while the chikore is said to eat fire.
— Kipling, 1904 [34]
Francolins are birds in the tribe Gallini that traditionally have been placed in the genus Francolinus, but now commonly are divided into multiple genera.
The Indian pond heron or paddybird is a small heron. It is of Old World origins, breeding in southern Iran and east to the Indian subcontinent, Burma, and Sri Lanka. They are widespread and common but can be easily missed when they stalk prey at the edge of small water-bodies or even when they roost close to human habitations.
The shikra is a small bird of prey in the family Accipitridae found widely distributed in Asia and Africa where it is also called the little 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 Accipiter species including the Chinese goshawk, Eurasian goshawk and Eurasian sparrowhawk. They have a sharp two note call and have the typical flap and glide flight. Their calls are imitated by drongos and the common hawk-cuckoo resembles it in plumage.
The spot-billed pelican or gray pelican is a member of the pelican family. It breeds in southern Asia from southern Iran across India east to Indonesia. It is a bird of large inland and coastal waters, especially large lakes. At a distance they are difficult to differentiate from other pelicans in the region although it is smaller but at close range the spots on the upper mandible, the lack of bright colours and the greyer plumage are distinctive. In some areas these birds nest in large colonies close to human habitations.
The red spurfowl is a member of the pheasant family and is endemic to India. It is a bird of forests, and is quite secretive despite its size. It has a distinctive call and is often hard to see except for a few seconds when it flushes from the undergrowth. It appears reddish and like a long-tailed partridge. The bare skin around the eye is reddish. The legs of both males and females have one or two spurs, which give them their name.
The white-browed wagtail or large pied wagtail is a medium-sized bird and is the largest member of the wagtail family. They are conspicuously patterned with black above and white below, a prominent white brow, shoulder stripe and outer tail feathers. White-browed wagtails are native to South Asia, common near small water bodies and have adapted to urban environments where they often nest on roof tops. The specific name is derived from the Indian city of Madras.
The purple-rumped sunbird is a sunbird endemic to the Indian Subcontinent. Like other sunbirds, they are small in size, feeding mainly on nectar but sometimes take insects, particularly when feeding young. They can hover for short durations but usually perch to lap nectar from flowers. They build a hanging pouch nest made up of cobwebs, lichens and plant material. Males are contrastingly coloured but females are olive above and yellow to buff below. Males are easily distinguished from the purple sunbird by the light coloured underside while females can be told apart from males by their whitish throats.
The red-vented bulbul is a member of the bulbul family of passerines. It is a resident breeder across the Indian subcontinent, including Sri Lanka extending east to Burma and parts of Bhutan and Nepal. It has been introduced in many other parts of the world and has established itself in New Zealand, Argentina, Tonga and Fiji, as well as parts of Samoa, Australia, USA and Cook Islands. It is included in the list of the world's 100 worst invasive alien species.
The yellow-throated bulbul is a species of songbird in the bulbul family of passerine birds. The species is endemic to southern peninsular India. They are found on scrub habitats on steep, rocky hills many of which are threatened by granite quarrying. It is confusable only with the white-browed bulbul with which its range overlaps but is distinctively yellow on the head and throat apart from the yellow vent. The calls of this species are very similar to that of the white-browed bulbul.
The baya weaver is a weaverbird found across the Indian Subcontinent and Southeast Asia. Flocks of these birds are found in grasslands, cultivated areas, scrub and secondary growth and they are best known for their hanging retort shaped nests woven from leaves. These nest colonies are usually found on thorny trees or palm fronds and the nests are often built near water or hanging over water where predators cannot reach easily. They are widespread and common within their range but are prone to local, seasonal movements mainly in response to rain and food availability.
The painted francolin or painted partridge is a species of francolin found in grassy areas in central and southern India and in the lowlands of southeastern Sri Lanka. They are easily detected by their loud calls especially during the breeding season. Thomas C. Jerdon noted that the species was found mainly in Central India south of the Narmada and to the east of the Western Ghats as well as the Chota Nagpur and Northern Circars. It can be confused only with the black francolin with which it partly overlaps and is said to sometimes hybridize. This species can be told apart from a black francolin female by the lack of a rufous hind collar and the white spots on the underside. The face is rufous and there is no dark stripe running behind the eye.
The Indian courser is a species of courser found in mainland South Asia, mainly in the plains bounded by the Ganges and Indus river system. Like other coursers, it is a ground bird that can be found in small groups as they forage for insects in dry open semi-desert country.
The large gray babbler is a member of the family Leiothrichidae found across India and far western Nepal. They are locally common in the scrub, open forest and gardenland. They are usually seen in small groups and are easily distinguished from other babblers in the region by their nasal call and the whitish outer feathers to their long tail. It is one of the largest babblers in the region.
The common woodshrike is a species of bird found in Asia. It is now usually considered a member of the family Vangidae. It is small and ashy brown with a dark cheek patch and a broad white brow. It is found across Asia mainly in thin forest and scrub habitats where they hunt insects, often joining other insectivorous birds. The form found in Sri Lanka which was treated as a subspecies is now usually considered a separate species, the Sri Lanka woodshrike.
The swamp francolin, also called swamp partridge, is a francolin species native to the foothills of the Himalayas in northern India and Nepal. It is considered extinct in the Ganges-Brahmaputra delta in Bangladesh. It is listed as Vulnerable on the IUCN Red List.
K. K. Neelakantan better known by his pen name Induchoodan, was a leading Indian ornithologist. He is widely regarded as a pioneer of the environmental movement in Kerala for popularizing bird study through his books written in Malayalam.
The bank myna is a myna found in the northern parts of South Asia. It is smaller but similar in colouration to the common myna, only differing in having brick-red naked skin behind the eyes instead of yellow. It is greyer on the underside and in this and in the presence of a slight tuft of feathers bears some resemblance to the jungle myna. They are found in flocks on the plains of northern and central India, often within towns and cities. Their range appears to be extending southwards into India. The name is derived from their habit of nesting almost exclusively in the earthen banks of rivers, where they excavate burrows and breed in large colonies.
The ashy minivet is a passerine bird of eastern Asia belonging to the minivet genus Pericrocotus in the cuckooshrike family Campephagidae. While most of the minivets have shades of yellow, orange and red in their plumage, this species has only greys, whites and blacks. The male is distinctive with a white face and black nape although females can be confused with the female of the brown-rumped minivet. They forage in the canopy, often along with other minivets and join mixed-species foraging flocks.
Perdicinae is a polyphyletic former subfamily of birds in the pheasant family, Phasianidae, regrouping the partridges, Old World quails, and francolins. Although this subfamily was considered monophyletic and separated from the pheasants, tragopans, junglefowls, and peafowls (Phasianinae) till the early 1990s, molecular phylogenies have shown that these two subfamilies actually constitute only one lineage. For example, some partridges are more closely affiliated to pheasants, whereas Old World quails and partridges from the Alectoris genus are closer to junglefowls. Due to this, the subfamily Perdicinae is no longer recognized by the International Ornithological Congress, with the species being split among 3 subfamilies.
