    兩者最大的差別是在raven屬於crow家族(corvus),所以前者可稱為crow但是不是每個後者都可稱為raven。

    還有通常raven的體型大過crow

    raven的叫聲比較低沉沙啞而crow的叫聲較高且帶鼻音

    raven的尾翼為尖型而crow的尾翼為扇型

    raven羽毛外端的形狀比crow的較為尖

    raven的壽命大致上來說比crow的要為長

    What's in a name: the difference between crows and ravens There is no clear difference between crows and ravens other than, by tradition, in any particular location, ravens are larger than the crows. This size difference sort of holds in Australia: the Australian Raven Corvus coronoides and Forest Raven C. tasmanicus are the largest species; the Little Crow C. bennetti is the smallest; and the Little Raven C. mellori and Torresian Crow C. orru are about the same intermediate size. Ravens also have grey bases to the black body feathers (white in the crows) and longer feathers (hackles) on the throat. Other than these, there are few obvious consistent differences. This conventional division of ravens and crows derives from the situation in England, where there are four species of these black birds. Two have typical black coloration - the large Common Raven C. corax and medium-sized Carrion Crow C. corone - and two smaller species have more distinctive appearances - the Rook C. frugilegus, with its naked face, and the diminutive Jackdaw C. monedula, with its grey head. There are few counterparts of the latter two species elsewhere in the world, and where two or more related birds occur together in other places, they generally resemble the typical English Raven and Crow, not the more distinctive species. 摘錄自http://www.amonline.net.au/factsheets/crows_ravens...      crow則有灰、白色的。
