松    鼠   

 松    鼠    是    一    种    漂    亮    的    小    动    物   , 乖    巧   , 驯    良   , 很    讨    人    喜    欢   。 它    们    面    容    清    秀   , 眼    睛    闪    闪    发    光   , 身    体    矫    健   , 四    肢    轻    快   。 玲    珑    的    小    面    孔   , 衬    上    一    条    帽    缨    形    的    美    丽    尾    巴   , 显    得    格    外    漂    亮   。 它    们    的    尾    巴    老    是    翘    起    来   , 一    直    翘    到    头    上   , 自    己    就    躲    在    尾    巴    底    下    歇    凉   。 它    们    常    常    直    竖    着    身    子    坐    着   , 像    人    们    用    手    一    样   , 用    前    爪    往    嘴    里    送    东    西    吃   。 可    以    说   , 松    鼠    最    不    像    四    足    兽    了   
 松    鼠    不    躲    藏    在    地    底    下   , 经    常    在    高    处    活    动   , 像    飞    鸟    一    样    住    在    树    顶    上   , 满    树    林    里    跑   , 从    这    棵    树    跳    到    那    棵    树   。 它    们    在    树    上    做    窝   , 摘    果    实   , 喝    露    水   。 只    有    树    被    风    刮    得    太    厉    害    了   , 才    到    地    上    来   。 在    平    原    地    区    是    很    少    看    到    松    鼠    的   。 它    们    不    接    近    人    的    住    宅   , 也    不    待    在    小    树    丛    里   , 只    喜    欢    住    在    高    大    的    老    树    上   。 在    清    朗    的    夏    夜   , 可    以    听    到    松    鼠    在    树    上    跳    着    叫    着   , 互    相    追    逐   。 它    们    好    像    很    怕    强    烈    的    日    光   , 白    天    躲    在    窝    里    歇    凉   , 晚    上    出    来    奔    跑   , 玩    耍   , 吃    东    西   
 松    鼠    不    像    山    鼠    那    样    一    到    冬    天    就    蛰    伏    不    动   。 它    们    是    十    分    警    觉    的   , 只    要    有    人    触    动    一    下    松    鼠    所    在    的    大    树   , 它    们    就    从    树    上    的    窝    里    跑    出    来    躲    到    树    枝    底    下   , 或    者    逃    到    别    的    树    上    去   。 松    鼠    轻    快    极    了   , 总    是    小    跳    着    前    进   , 有    时    也    连    蹦    带    跑   。 它    们    的    爪    子    是    那    样    锐    利   , 动    作    是    那    样    敏    捷   , 一    棵    很    光    滑    的    高    树   , 一    忽    儿    就    爬    上    去    了   。 松    鼠    在    秋    天    拾    榛    子   , 塞    到    老    树    空    心    的    缝    隙    里   , 塞    得    满    满    的   , 留    到    冬    天    吃   。 在    冬    天   , 它    们    也    常   
 用    爪    子    把    雪    扒    开   , 在    雪    下    面    找    榛    子   
 松    鼠    的    窝    通    常    搭    在    树    枝    分    杈    的    地    方   , 又    干    净    又    暖    和   。 它    们    搭    窝    的    时    候   , 先    搬    些    小    木    片   , 错    杂    着    放    在    一    起   , 再    用    一    些    干    苔    藓    编    扎    起    来   , 然    后    把    苔    藓    挤    紧   , 踏    平   , 使    那    建    筑    物    足    够    宽    敞   、 足    够    坚    实   。 这    样   , 它    们    可    以    带    着    儿    女    住    在    里    面   , 既    舒    适    又    安    全   。 窝    口    朝    上   , 端    端    正    正   , 很    狭    窄   , 勉    强    可    以    进    出   。 窝    口    有    一    个    圆    锥    形    的    盖   , 把    整    个    窝    遮    蔽    起    来   , 下    雨    时    雨    水    向    四    周    流    去   , 不    会    落    在    窝    里   
 松    鼠    通    常    一    胎    生    三    四    个   。 小    松    鼠    的    毛    是    灰    褐    色    的   , 过    了    冬    就    换    毛   , 新    换    的    毛    比    脱    落    的    毛    颜    色    深    些   。 它    们    用    爪    子    和    牙    齿    梳    理    全    身    的    毛   , 身    上    总    是    光    光    溜    溜   、 干    干    净    净    的
