Study Notes
Bird Behavior and Emotional Contagion
- Birds exhibit emotional contagion, where one bird's alarm prompts others to flee, without assessing the threat.
- Research on western evening grosbeaks shows coordinated anti-predatory scanning in clustered groups compared to linear groups.
- Birds in a circle demonstrated more coordinated scanning behaviors, showing a greater ability to share information than those in a line.
- Birds in linear feeding positions displayed more nervousness and frequent body/head adjustments as they lacked visibility of fellow flock members.
- Limited visibility hinders emotional contagion in linear formations, as birds only have knowledge of those nearby.
