Study Notes
Bird Behavior and Emotional Contagion
- Birds exhibit emotional contagion, where one bird's fear triggers a response in others, leading to immediate flight.
- Research involving western evening grosbeaks showed coordinated scanning patterns in birds who could see the whole flock.
- Birds in a line were less coordinated when scanning, appearing more nervous, and changing their body and head positions more frequently than birds in a circle.
- Grosbeaks in a circle had better visibility of all individuals, allowing for easier assessment of the threat.
- Grosbeaks in a line could only see their closest neighbor, limiting awareness of the flock's behaviour and potentially increasing fear.
- Emotional contagion within the linear grouping was limited to only the closest neighbors.
