Sibiriskt snöfår eller asiatiskt snöfår (Ovis nivicola) är en art i släktet får som förekommer i nordöstra Sibirien.

Kännetecken

Djuret når en kroppslängd mellan 140 och 160 centimeter och därtill kommer en cirka 10 centimeter lång svans. Mankhöjden ligger mellan 95 och 110 centimeter och vikten mellan 60 och 120 kilogram. Pälsen har under sommaren en gråbrun färg och under vinter blir den ullig med ljusbrun färg. De främre extremiteterna är mörkbruna och vid stjärten finns en ljusare fläck. Fårets nos är vitaktig och står i kontrast till den övriga pälsen. Öronen är små. Horn finns hos bägge kön men dessa är tydligt mindre än hos tjockhornsfåret. Hannarnas horn vrider sig bakåt och blir upp till 90 centimeter långa. Honor har tydligt mindre horn som bara har en liten böjning.

Utbredning och systematik

Sibiriskt snöfår är en av fem arter i släktet Ovis. Dess närmaste släktingar är tjockhornsfåret och amerikanskt snöfår.

Antalet underarter är omstridd. För närvarande erkänns 5 underarter.[källa behövs] Underarten O. n. borealis lever i Putoranabergen. De andra underarterna lever öster om floden Lena fram till Tjuktjerhalvön och Kamtjatka.

Ekologi

Sibiriskt snöfår förekommer i bergiga trakter och har god klätterförmåga. De lever i flockar som vanligen är uppdelade efter kön. Hangrupperna är hierarkiska vilken även spelar roll under parningstiden då dominanta djur har företräde. Hierarkin baseras på hornens storlek och utifrån strider, då djuren springer med sänkt huvud och slår hornen mot varandra.

Som växtätare lever de främst gräs och lav.

Efter dräktigheten, som varar i ungefär 8,5 månader föder honan vanligen en unge. Efter 4 till 6 månader sluter honan att ge di. Honor blir könsmogna efter 2 år och hannar efter 5 år. Medellivslängden är 9 år.

Status och hot

Arten hotas på grund av jakt men IUCN kategoriserar ändå djuret som livskraftig (LC). Däremot kategoriseras underarten i Putoranabergen som sårbar (VU).

We could distinguish at the head of the valley rows
of volcanic pinnacles, some 5,000 feet high, with pre-
cipitous snow-slides shooting down the gullies between
them. They ran westward of the main peak, and
appeared to be first-rate ground for sheep.
A distance of about six miles as yet intervened, and
it took us at least three hours before we reached the
more abrupt slopes of the towering crags. As we
were preparing for the last scramble I spied a large
bear some lour hundred yards above us. As I
watched him through the glass, digging the earth
and slowly advancing at right angles from us, his
coat seemed unusually light in colour, almost white.
As he was on our way, I suggested a stalk, and, hiding
from view, followed a lateral ravine in his direction.
Unfortunately, on reaching the commanding ridge,
alder bushes, on which we counted for concealment,
had l)ecome scarce, and further advance in the open
would have involved certain failure. Bruin was now
two hundred and fifty yards off, and as he appeared
to have no intention of coming- anv nearer, I had to

take my chance. Out of five consecutive shots, the
fifth at least reached its destination, for the beast,
which had remained motionless, as if thunder-stricken
by the cracks of the rifle, emitted a loud roar, and
pelted downhill to my right into patches of dense
brushwood, where we could locate him by the waving
of the branches above him, as he forced his way
through. Though we found blood on his tracks, he
was strong enough to pursue his course through the
thicklv entangled scrub, in the midst of which it
would be a dangerous matter to tackle a wounded
bear. The rifie was of no avail, and the General
proposed to abandon a chase which involved such
risk. Time being precious. I agreed to this wise
suggestion, and reluctantly leaving the animal to its
unhappy fate, proceeded to climb a perpendicular
slope towards the left ridge of the valley, along
which we journeyed to a low saddle, where we settled
down to spy. There mosquitoes again gathered round
us in countless numbers ; my companion, who wore no
gloves, declined to use the spare Zeiss I had lent him
and kept his hands in his pockets.
