CROWS pair up for life?

Question

do CROWS pair up for life?

Answer 1

In general, it appears that they do mate for life. Unless a mate is killed or severely incapacitated, crows appear to stay with the same mate year after year. It is possible, however, for exceptions to occur. Generally this would happen in the case of a young pair of birds that mated but bred unsuccessfully. They might break the pair bond and try again with someone else. I had one young male return home after an unsuccessful first nesting attempt. Because the female was unmarked I do not know if she died or also went home to her folks.  Interesting site below.
