Study Notes
Bird Behavior and Emotional Contagion
- Birds exhibit emotional contagion, reacting to a startled bird by flying off.
- They do not assess the threat, but react instinctively.
- Research on western evening grosbeaks showed that birds in a circle displayed more coordinated scanning behaviors than those in a line.
- Grosbeaks in a line exhibited increased nervousness.
- They altered their body and head positions more frequently compared to birds in a circle.
- The lack of visibility between grosbeaks in a line limited their ability to see and assess their flockmates' reactions, making it more challenging to observe emotions or coordinated actions from distant flockmates.
