Caucasian squirrel

TheCaucasian squirrel(Sciurus anomalus) orPersian squirrel, is atree squirrelin the genusSciurusfound intemperate broadleaf and mixed forestsin south-western Asia.
The species is traditionally said to have first been described in 1778 byJohann Friedrich Gmelinin the 13th edition ofSystema Naturae,and namedSciurus anomalus.However, this work was actually published in 1788,so the true first description was made byJohann Anton Güldenstädtin 1785.Gmelin made reference to this in the 1788 work, citing Güldenstädt as theauthor.
Caucasian squirrels are small tree squirrels, with a total length of 32 to 36 cm (13 to 14 in), including the 13 to 18 cm (5.1 to 7.1 in) tail, and weighing 250 to 410 g (8.8 to 14.5 oz). The color of the upper body fur ranges from greyish brown to pale grey, depending on the subspecies, while that of the underparts is rusty brown to yellowish, and that of the tail, yellow brown to deep red. The claws are relatively short, compared with those of other tree squirrels, and females have either eight or ten teats.
Samuel Griswold Goodrichdescribed the Caucasian squirrel in 1885 as "Its color is grayish-brown above, and yellowish-brown below".
Caucasian squirrels are native to south-western Asia, where they are found from Turkey, and the islands ofGökçeadaandLesbosin the west,Iranin the southeast, and as far asIsraelandJordanin the south.It is one of only two species of thegenusSciurusto be found on Mediterranean islands,and, althoughEurasian red squirrelshave been recently introduced to some areas, is the only species ofSciurusnative to the wider region.
The species mainly lives in forested areas dominated byoak,pine, andpistachio,up to altitudes of 2,000 metres (6,600 ft).
Three subspecies are recognised:
The squirrels arediurnal, and solitary, although temporary groups may forage where food is plentiful.  Their diet includes nuts, seeds, tree shoots, and buds,with the seeds of oakand pinebeing particularly favored. Like many other squirrels, they cache their food within tree cavities or loose soil, with some larders containing up to 6 kg (13 lb) of seeds.
They live in trees, where they make theirdens, but frequently forage on the ground, and are considered lessarborealthan Eurasian red squirrels. They commonly nest in tree hollows lined with moss and leaves, and located 5 to 14 m (16 to 46 ft) above the ground, but nests are also sometimes found under rocks or tree roots. Their alarm call is high-pitched, and said to resemble the call of theEuropean green woodpecker, and they mark their territories with urine and dung.
Breeding occurs throughout the year, but is more common in spring or autumn. Litters range from two to seven, with three or four being typical, and the young are fully mature by five or six months of age.
A survey in 2008 found that the species remained abundant within Turkey, however declines are noted in population within theLevantregion. The guides for a survey in 1993 in Israel stated that they considered the species to be nearly extinct within the area studied. Whilst the Caucasian squirrel is threatened by poaching and deforestation, the declines recorded are not sufficient to qualify them as anything other than "Least Concern" by theInternational Union for Conservation of Nature.Hunting of the species is banned by theCentral Hunting Commission, and the Caucasian squirrel is protected by theBern Conventionand theEU Habitats Directive.
