![]() ![]() Several fossil species have been described, but their distinctness is not firmly established in all cases: Prehistorically, the genus Gallus was found all over Eurasia in fact, it appears to have evolved in southeastern Europe. Java, Bali, Lombok, Komodo, Flores, Rinca, and small islands linking Java with Flores, Indonesia Indian Peninsula, but extends into Gujarat, Madhya Pradesh, south Rajasthan, and Pakistani Punjab India, Pakistan, eastwards across Indochina and southern China and into Malaysia, Singapore, Philippines and Indonesia More recent phylogenetic evidence supports the closest relatives of Gallus being the bamboo partridges in the genus Bambusicola, from which they diverged about 15 million years ago. Sri Lankan junglefowl – Gallus lafayettiiĬladogram showing the phylogenetic relationships between the species ![]() As the publication date of Linnaeus's sixth edition was before the 1758 starting point of the International Commission on Zoological Nomenclature, Brisson and not Linnaeus is considered as the authority for the genus. This pairwise divergence time was also the same between the other three junglefowls and the pheasant. However, the red junglefowl and common pheasant are now known to have diverged about 18–23 million years ago, and belong to different subfamilies. The Swedish naturalist Carl Linnaeus had introduced the genus Gallus in the 6th edition of his Systema Naturae published in 1748, but Linnaeus dropped the genus in the important tenth edition of 1758 and put the red junglefowl together with the common pheasant in the genus Phasianus. ![]() The type species is the red junglefowl ( Gallus gallus). The genus Gallus was erected by the French scientist Mathurin Jacques Brisson in his Ornithologie published in 1760. The Sri Lankan junglefowl is the national bird of Sri Lanka. One of the species in this genus, the red junglefowl, is of historical importance as the direct ancestor of the domestic chicken, although the grey junglefowl, Sri Lankan junglefowl and green junglefowl are likely to have also been involved. The junglefowl are omnivorous, eating a variety of leaves, plant matter, invertebrates such as slugs and insects, and occasionally small mice and frogs. Aggressive social hierarchies exist among both females and males, from which the term "pecking order" originates. Females and males do not form pair bonds instead, the species has a polygynandrous mating system in which each female will usually mate with several males. These duties are performed by the drab and well- camouflaged female. These are large birds, with colourful plumage in males, but are nevertheless difficult to see in the dense vegetation they inhabit.Īs with many birds in the pheasant family, the male takes no part in the incubation of the egg or rearing of the precocial young. Īlthough originating in Asia, remains of junglefowl bones have also been found in regions of Chile, which date back to 1321–1407 CE, providing evidence of possible Polynesian migration through the Pacific Ocean. They diverged from their common ancestor about 4–6 million years ago. Fewer crowds.Junglefowl are the only four living species of bird from the genus Gallus in the bird order Galliformes, and occur in parts of South and Southeast Asia. ![]() October to December: All-day offshore winds, small swells, and possible long, flat spells. June to September: Larger consistent swells (waist high to overhead) and cross-shore winds at The Point, although some inside sections of The Point are protected. This is the best time to surf this region as conditions are usually good for both The Point and The Reef. March to May: Offshore winds, medium-sized swells (waist to head-high with the occasional bigger day). Swell direction and winds are good for The Reef. January/February: All-day offshore winds, but inconsistent swell and generally the wrong swell direction for The Point. Surfboard rental is also available from Batu Karas Surf Club (shortboards and longboards), for approximately US$15/day. Surf lessons are available with experienced locals – just book and pay during your stay. While it’s not one of the most consistent Indonesian surf destinations, there are still plenty of waves on offer. If you’re looking for fun, user-friendly waves, Batu Karas ticks all the boxes. ![]()
