Study Notes
Bird Behavior and Emotional Contagion
- Birds exhibit emotional contagion, reacting to a startled bird's flight by following it.
- They do not assess the perceived threat's validity.
- This study observed Western Evening Grosbeaks.
- Birds in a circular formation showed more coordinated scanning behavior than birds in a linear formation.
- Linear-formation birds showed more nervousness, changing body and head positioning more frequently.
- The cause of increased nervousness in the linear formation may be due to limited visibility of other flockmates' actions.
- Emotional contagion is limited in linear formations (only nearest neighbors can perceive each other's actions).
