Acrobatics of Yellow-throated Martens

  • 10 years ago
The yellow-throated marten (Martes flavigula), also known as the kharza, is an Asian species of marten which is listed by the IUCN as Least Concern due to its wide distribution, evidently relatively stable population, occurrence in a number of protected areas, and lack of major threats. The yellow-throated marten is the largest marten in the Old World, with a tail more than half its body length. Its fur is brightly coloured, consisting of a unique blend of black, white, golden-yellow and brown. It is an omnivore, whose sources of food range from fruit and nectar to small deer. The yellow-throated marten is a fearless animal with no natural predators, because of its powerful build, its bright colouration and unpleasant odour. It shows little fear of humans or dogs, and is easily tamed.

Although similar in several respects to the smaller beech marten, it is sharply differentiated from other martens by its unique color and the structure of its baculum. It is probably the most ancient form of marten, having likely originated during the Pliocene, as indicated by its geographical distribution and its atypical colouration.

The first written description of the yellow-throated marten in the Western World is given by Thomas Pennant in his History of Quadrupeds (1781), in which he named it "White-cheeked Weasel". Pieter Boddaert featured it in his Elenchus Animalium with the name Mustela flavigula. For a long period after the Elenchus' publication, the existence of the yellow-throated marten was considered doubtful by many zoologists, until a skin was presented to the Museum of the East India Company in 1824 by Thomas Hardwicke.

The yellow-throated marten is a large, robust, muscular and flexible animal with an elongated thorax, a small pointed head, a long neck and a very long tail which constitutes about 2/3 of its body length. The tail is not as bushy as that of other martens, and thus seems longer than it actually is. The limbs are relatively short and strong, with broad feet. The ears are large and broad, but short with rounded tips. The soles of the feet are covered with coarse, flexible hairs, though the digital and foot pads are naked and the paws are weakly furred. The skull is similar to that of the beech marten, but is much larger. The baculum is S-shaped, with four blunt processes occurring on the tip. It is larger than other Old World martens; males measure 500--719 mm in body length, while females measure 500--620 mm. Males weigh 2.5-5.7 kg (5.5-12.6 lbs), while females weigh 1.6-3.8 kg (3.5-8.4 lbs). The anal glands sport two unusual protuberances, which can be used to secrete a strong smelling liquid for defensive purposes.

The yellow-throated marten has relatively short fur which lacks the fluffiness of the pine marten, sable and beech marten. The winter fur differs from that of other martens by its relative shortness, its harshness and its lustre. It is also not as dense, fluffy and compact as that of other martens. The hairs on the tail are short and of equal length over the whole tail. The summer fur is shorter, sparser, less compact and lustrous. The colour of the pelage is unique among martens, being bright and variegated. The top of the head is blackish brown with shiny brown highlights, while the cheeks are somewhat more reddish, with a mixture of white hair tips. The back of the ears are black, while he inner portions are covered with yellowish-grey. The fur is a shiny brownish-yellow colour with a golden tone from the occiput along the surface of the back. The colour becomes browner on the hind quarters. The flanks and belly are bright yellowish in tone. The chest and lower part of the throat are a brighter, orange-golden colour than the back and belly. The chin and lower lips are pure white. The front paws and lower forelimbs are pure black, while the upper parts of the limbs are the same colour as the front of the back. The tail is of a shiny pure black colour, though the tip has a light, violet wash. The base of the tail is greyish-brown. The contrasting marks of the head and throat are likely recognition marks.
