Perny’s Long-nosed Squirrel <i>Dremomys pernyi</i> <b>French:</b> Ecureuil de Perny / <b>German:</b> Perny-Rotwangenhdérnchen / <b>Spanish:</b> Ardilla de hocico largo de Perny <b>Taxonomy.</b> Sciurus pernyi Milne-Edwards, 1867, “les montagnes de la principaute de Moupin [Muping]” (= Baoxing, Sichuan, China). Eight subspecies are recognized. <b>Subspecies and Distribution.</b> D.p.pernyiMilne-Edwards,1867—C&amp;SChina(SGansu,SShaanxi,WSichuan,NWYunnan,andWTibet=Xizang).

D.p.owston:Thomas,1908—Taiwan. D. p. senex G. M.. Allen, 1912 — EC China (Hubei and N Guizhou). <b>Descriptive notes.</b> Head-body 170-203 mm, tail 138-180 mm; weight 160-225 g. Perny’s Long-nosed Squirrel has an agouti gray dorsum; it lacks a reddish cheek and a reddish hip patch. Venter is whitish, with a reddish brown patch in perineal region. Ventral surface of tail is buffy gray. Nominate subspecies pernyi is larger and lighter gray than the other subspecies. Subspecies calidior is similar to senex, but its dorsum is a warmer brown (almost olive-brown), venter is whiter, and it has buffy thigh patches. Subspecies flavior is smaller than nominate pernyi and is darker olive on dorsum. Subspecies howelli is generally darker above than the other subspecies, with a short mid-dorsal stripe and a darker anal patch. Subspecies mus is larger than howelli, with mid-dorsal stripe barely visible, and with a dull buff coloration on front side of limbs. Dorsum of modestus is dull brown, with inconspicuous ear patches; and venteris tinged buff, especially posteriorly. Dorsum of owstoni is brindled or grizzled buff and black, venteris dull yellowish or orangish, and throat is grayish white. Subspecies senex has a whiter patch behind ear than nominate pernyi, throat is white, and underside oftail is more ocherous than white. <b>Habitat.</b> Coniferous and evergreen broadleafforests, at elevations of ¢.2000-3500 m. Perny’s Long-nosed Squirrel inhabits protected planted pine (Pinus, Pinaceae) forests in the Cangshan Mountains and the Erhai Lake National Reserve (Yunnan, China), but not until pines are 6-10 years old or older. Abundance of Perny’s Long-nosed Squirrel in this reserve is positively correlated with amount of shrub growth, and it is less common in unprotected forests, which have fewer shrubs of the same ages, outside the reserve. Human disturbances in unprotected forests causes a reduction in diversity of undergrowth, which delays colonization and reduces population levels of Perny’s Long-nosed Squirrel. It is considered important for the pines’ seed dispersal. <b>Food and Feeding.</b> Perny’s LLong-nosed Squirrel has been known to prey on eggs and young of blue-crowned laughing thrush (Dryonastes courtoisi) in Wuyuan County (Jiangxi, China). <b>Breeding.</b> There is no information available for this species. <b>Activity patterns.</b> Perny’s L.ong-nosed Squirrel is diurnal and mostly terrestrial, but spends some time in trees. It is a highly vocal and loud species. <b>Movements, Home range and Social organization.</b> There is no information available for this species. <b>Status and Conservation.</b> Classified as Least Concern on The IUCN Red List. Perny’s Long-nosed Squirrel has a wide distribution, and a presumed large population. It is threatened by habitat degradation due to shifting cultivation practices and hunting for meat. <b>Bibliography.</b> Allen (1940), Corbet &amp; Hill (1992), He Fengi &amp; Lin Jiansheng (2006), Jordan et al.
