豺的叫声怎么形容？

This carrion-feeding and cowardly Dog is a near relative to the Wolf, but is much smaller and lives only in the warm regions of Asia and Africa.
According to the natives, the African jackals actually help lions to find their prey-and it is well known that lions do not seem to resent the presence of jackals when they are having a meal. The jackals wait until the lion has finished, and then help themselves to what remains. A jackal’s cry is a long, wailing, blood-curling howl. A cry from one member of the pack is enough to set the whole pack shrieking, a chorus which is kept up through most of the night.

这种食腐并且胆怯的犬科动物是狼的近亲，但比狼小得多而且只生活在温暖的亚洲及非洲地区。
根据土著人的说法，非洲豺实际上会帮助狮子寻找它们的猎物--广为人知的是狮子在享用它们的食物时并不介意豺的出现。豺在一边等狮子吃完然后才享用剩下的食物。豺的叫声是一种拉长的，凄厉的，让人血脉翻腾的嗥叫。一群豺中一只的叫声就足够引起整群号叫，形成一出维持大半夜的合唱。
