Jungle Fowl
Pheasant General Information ... Pheasant Species / Pheasant Taxonomy ... Breeding Pheasants ... Pheasant Photo Gallery ... Housing Pheasants ... Pheasant Diseases
Junglefowl are a group of four living species of bird in the pheasant family which occur in India, Sri Lanka and south east Asia.
These are large birds, with colourful male plumage, but are nevertheless difficult to see in the dense vegetation they inhabit.
As with many birds in the pheasant family, the colourful male plays no part in the incubation of the egg or rearing of the precocial young. These duties are performed by the drab and well-camouflaged female.
The junglefowl are seed-eaters, but insects are also taken, particularly by the young birds.
One of the species in this genus, the Red Junglefowl, is of historical importance as the likely ancestor of the domesticated chicken.
Genetic pollution and threat of extinction
- Wild Jungle fowl, specifically Red Junglefowl in India and South Asia are the ancestor of all Poultry Chickens. These are thought to be facing a serious threat of extinction because of genetic pollution which is occurring at the edge of forests where domesticated free ranging chickens are commonly kept in bordering villages and towns.
Species
- Red Junglefowl, Gallus gallus
- Sri Lanka Junglefowl, Gallus lafayetii
- Grey Junglefowl, Gallus sonneratii
- Green Junglefowl, Gallus varius
Prehistorically, the genus Gallus was found all over Eurasia; in fact it appears to have evolved in southeastern Europe. Several fossil species have been described, but their distinctness is not firmly established in all cases:
- Gallus aesculapii (Late Miocene/Early Pliocene of Greece) - possibly belongs into Pavo
- Gallus moldovicus (Late Pliocene of Moldavia) - sometimes misspelt moldavicus
- Gallus beremendensis (Late Pliocene/Early Pleistocene of E Europe)
- Gallus karabachensis (Early Pleistocene of Nagorno-Karabakh)
- Gallus tamanensis (Early Pleistocene? of Taman Peninsula)
- Gallus kudarensis (Early/Middle Pleistocene of Kudaro, South Ossetia)
- Gallus europaeus (Middle Pleistocene of Italy)
- Gallus sp. (Middle/Late Pleistocene of Trinka Cave, Moldavia)
- Gallus imereticus (Late Pleistocene of Gvardjilas-Klde, Imeretia)
- Gallus meschtscheriensis (Late Pleistocene of Soungir, Russia)
- Gallus georgicus (Late Pleistocene - Early Holocene of Georgia)
- Gallus sp. (Late Pleistocene of Krivtcha Cave, Ukraine)
- Gallus sp. (Early Holocene of Dnieper region)
