What is a flock of crows called?
A group of crows is known as a murder. I don’t know about you, but that is enough of a reason for me to stay as far away from a group of them as possible. I wouldn’t want them getting any ideas. Scientists also use the word ‘flock’ which is much less violent. To find more information click here: http://www.birds.cornell.edu/crows/crowfaq.
