|种：||西方狍 C. capreolus|
西方狍（Capreolus capreolus）是一種分佈於歐洲、裏海及安那托利亞的鹿，故被命名為西方狍。該物種有一種名叫東方狍（Capreolus pygargus）的近親，主要分佈於中東、中國及西伯利亞等地方。為夜行性動物，主要進食果實等食物為生。The two species meet at the Caucasus Mountains, with the European species occupying the southern flank of the mountain ranges and adjacent Asia Minor and the Siberian species occupying the northern flank of the mountain ranges. Within Europe, the European Roe Deer occurs in most areas, with the exception of northernmost Scandinavia (north of Narvik) and some of the islands, notably Iceland, Ireland, and the Mediterranean Sea islands; in the Mediterranean region it is largely confined to mountainous regions, and is absent or rare at low levels.
English roe is from Old English raha, from Proto-Germanic *raikhon, cognate to Old Norse ra, German Reh. The word is attested in the 5th century Caistor-by-Norwich astragalus inscription as raïhan. Ultimately perhaps from a PIE root *rei- "streaked, spotted."
西方狍身長95-135 厘米（3.1 - 4.4 尺），膊頭闊65-75 厘米（2.1 - 2.5 尺），體重約15-30 公斤（33-66 磅），在鹿科動物中屬於體型較小的物種。牠有着短小和直豎的叉角，更有帶紅色的身體及灰白色的臉。西方狍善於偽裝，在夏天時會呈金紅色作偽裝；冬天時身體變會黑化，呈啡色甚至是黑色，及加上白色的臀部。另外，牠僅短2-3 厘米（0.8 - 1.2 寸）的尾巴短得幾乎看不到，這亦有助隱藏自己。 西方狍的第一和第二對的叉角都沒有分叉，長度亦較短（5-12 厘米，即 2 - 4.7 寸），但當雄鹿在良好的情況下發育時，叉角便會增高至20-25厘米（8 - 10寸），並長出二至三個分叉，罕見的甚至有四個。When the male's antlers begin to regrow, they are covered in a thin layer of velvet-like fur which disappears later on after the hair's blood supply is lost. Males may speed up the process by rubbing their antlers on trees, so that their antlers are hard and stiff for the duels during the mating season. Unlike most cervids, roe deer begin regrowing antlers almost immediately after they are shed.
西方狍一般在黄昏时间迅速而优雅地活动，主要生活在树林中，偶尔也在草原和稀疏的森林里活动。主要以草、树叶、浆果和嫩枝为食，尤其喜欢湿润的嫩草，例如雨后第二天的草。 Roe deer will not generally venture in to a field that either has livestock in it (ie. sheep, cattle), or has recently had it in; this is because the livestock will make the grass very unclean. A pioneer species commonly associated with biotic communities at an early stage of succession, during the Neolithic period in Europe the Roe Deer was abundant, taking advantage of areas of forest or woodland cleared by Neolithic farmers (Boyle, 2006).
一般來說，西方狍在野外生存最長的壽命為十年。當牠們生命快要結束時，牠們會像狗一樣的叫及亮出其白色的臀部。Rump patches differ between the sexes, with the white rump patches heart-shaped on females and kidney-shaped on males. Males may also bark, make a low grunting noise or make a high pitched wolf-like whine when attracting mates during the breeding season, often luring multiple does into their territory. The Roe Deer spends most of its life alone, preferring to live solitary except when mating during the breeding season.
The polygamous Roe Deer males clash over territory in early summer and mate in early fall. During courtship, when the males chase the females, they often flatten the underbrush leaving behind areas of the forest in the shape of a figure eight called 'roe rings'. Males may also use their antlers to shovel around fallen foliage and dirt as a way of attracting a mate. Roebucks enter rutting inappetence during the July and August breeding season. Females are monoestrous and after delayed implantation usually give birth the following June, after a ten-month gestation period, typically to two spotted fawns of opposite sexes. The fawns remain hidden in long grass from predators until they are ready to join the rest of the herd; they are suckled by their mother several times a day for around three months. Roe deer adults will often abandon their young if they sense or smell that an animal or human has been near it. Young female roe deer can begin to reproduce when they are around 16 months old.
