Crows: Symbol of Bad Luck? Or Intelligent Birds?


Crows are common black birds well known for their intelligence. They are found all over the world. Some crows are solitary while others stay in groups. A group of crows is called a murder. When a crow dies, the murder will surround the deceased one. This behavior can be interpreted as a way of mourning their dead and also to find out what killed them.

There are nearly 40 species of crows in many different sizes. An American crow measures around 17.5 inches (45 cm). A fish crow is 19 inches (48 cm).

Crows sometimes have been found eating in garbage cans according to ADW.
