Some Canada Jays move to different territories, usually with new mates, from one breeding season to the next.

What is post-breeding dispersal?

occurs after breeding and when the young are grown.

Territorial behaviors subside and adults and young may wander beyond their territory.

Why do animals exhibit post-breeding dispersal?

In which species is post-breeding dispersal common?

It is very common in birds but can occur in many other species.
