Bird Behavior and Emotional Contagion
- Birds exhibit emotional contagion, where one bird's alarm triggers similar reactions in others.
- They don't wait to assess the threat.
- Birds in a circular formation show better coordinated vigilance than birds feeding in a line.
- Birds in a line show more nervous behavior, with more frequent body and head position changes.
- Lack of visibility of the entire flock (limited visibility) among birds in a line may make them more fearful because they cannot see what other flock members are doing.
- Emotional contagion is limited in a linear arrangement because grosbeaks can only see immediately adjacent birds.
