Crows belong to the family Corvidae. Crows are believed to be the most intelligent of all birds. There is very little wonder why they have been revered and worshipped over the centuries.
The American Crow, Corvus brachyrynchos, when fully grown is 17" to 21" (from tip of bill to tip of tail). Weight when fully grown; approximately one pound.
There is no way to tell by physical appearance alone, as to whether a crow is male or female. DNA testing of blood will indicate sex. Close study of crows in their daily life, especially during nesting season may provide a clue as to sex, however, this is not something that many people will be able to observe.
