Birdfinding.info ⇒ The wild ancestor of the domestic chicken remains locally common across much of its original range, where it is can be found in protected natural areas, including most of the national parks, wildlife refuges, and nature sanctuaries of northern India, Nepal, Bhutan, southern China, and southeast Asia. In Hawaii, introduced populations, most heavily hybridized with domestic chickens, are locally common on the main islands, especially in the lowlands of Kauai, where many appear to be nearly pure.
Red Junglefowl
Gallus gallus
Family: Phasianidae
Southeastern Asia; widely introduced across the tropical Pacific. Inhabits forests, other woodlands, and adjacent openings.
Native populations occur from northern and central India (Kashmir, Madhya Pradesh, and Andhra Pradesh) east to southern China (locally in Yunnan, Guangxi and Hainan) and south through Indochina, the Malay Peninsula, Sumatra, and Java to Bali.
Introduced populations are established on many Pacific Islands: the Philippines (throughout), northeastern Borneo, Sulawesi, the Lesser Sundas east to Timor, Palau, Vanuatu, New Caledonia, New Zealand’s North Island, Fiji, Samoa, Tonga, the Cook Islands, Moorea, Tahiti, the Marquesas, Hawaii. Most, if not all, of the introduced populations east of Indonesia have hybridized with domestic chickens to varying degrees, which confuses their current identity.
Identification
Red Junglefowl is the principal, or perhaps only, ancestor of the domestic chicken, so the general resemblance between them is strong. The male, in particular, could easily be mistaken for a bantam rooster, while the female is less similar to a barnyard hen. Both sexes have features that rarely if ever appear in their domestic counterparts, the most consistent being gray legs.

The male’s plumage is colorful and complex, with several contrasting feather groups. Most prominent is its orange cape or neck-ruff, which it erects like an umbrella when displaying or sparring with rivals.

The male’s upperparts have panels of chestnut and glossy greenish- or bluish-black, the secondaries are coppery, and the rump is white. The underparts are mostly black, with a greenish gloss in strong light.
The tail is black and wedge-shaped, with glossy greenish-black covert feathers that extend across the tail. Two of these feathers are greatly elongated and sickle-shaped, and arch over the tail.

The facial skin is bare and bright red, and includes a tall comb and wattles on the throat and cheeks. In males of some populations, the cheek wattles are white.

Female differs noticeably from domestic hen in the appearance of its tail, which is long, wedge-shaped, and typically held horizontal.
Its overall coloration is medium-brown, with a blackish or dark-brown tail, pale-brown breast, dense orange and black streaks on the head and neck, and diffuse whitish streaks on the breast and upperparts.

Female’s facial skin is mostly bare and dull-pink. As with males, in some populations the females have white patches on the cheeks.

Voice. Male’s crowing call is much a like that of a domestic rooster, but higher-pitched, scratchier, and briefer, consisting of four quick syllables:
Clucks exactly like a chicken:
Cf. Domestic Chicken. The distinction between Red Junglefowl and domestic chicken has become fluid and ambiguous on the many Pacific islands where hybridization has produced a full spectrum of appearances, some nearly identical to wild junglefowl and many that differ in obvious ways. In Hawaii, for example, the distinction may be a lost cause: the feral populations are not quite junglefowl or chickens anymore.
In regions where Red Junglefowl occurs without extensive hybridization, they are readily distinguishable from wild-living chickens that occur in the same areas. A general rule of thumb is to focus on the legs: Red Junglefowl has gray legs, whereas domestic chickens generally have yellow or orange legs.
Although many domestic roosters resemble male Red Junglefowl, very few have exactly the same set of intensely colored feather panels, the wedge-shaped tail, and the overarching glossy-greenish covert feathers.

Most domestic hens do not closely resemble female Red Junglefowl, which can usually be distinguished by its long, wedge-shaped tail held horizontal, and the bright streaks on its neck and breast.However, as with the males, some hybrid populations have a spectrum that includes many morphologically intermediate appearances: such as medium-length tails held diagonally, and fine streaks distributed over varying portions of the neck and body.
Cf. Gray Junglefowl. Red and Gray Junglefowl have adjacent ranges and may overlap to some extent in central India. Males of the two species have entirely different plumages, but females are somewhat similar.
Female Gray Junglefowl is chicken-shaped, with a short tail that it holds partially cocked. Its tail is pale brown and barred, whereas Red’s is blackish and unmarked. Female Gray’s legs are yellow, whereas Red’s are gray. Female Gray also differs from Red in having extensive broad, white streaks on the underparts.
Cf. Green Junglefowl. Red and Green Junglefowl coexist naturally on Java and Bali, and through introductions elsewhere in Indonesia. Males of the two species have entirely different plumages, but females are somewhat similar.
Female Green Junglefowl is chicken-shaped, with a short tail that it holds partially cocked. Its plumage is dominated by a complex brown-and-black scaled pattern that varies in shape from rounded on the underparts, neck, and mantle, to angular on the wings, lower back, and rump. The shades of brown are grayer on the neck and breast, and rusty on the wings and rump—whereas female Red’s overall coloration is approximately the opposite: rustier on the neck and breast, and duller on the wings and rump.
Notes
Polytypic species consisting of five recognized subspecies.Red Junglefowl is the principal ancestor of the domestic chicken.
