Study Notes

Bird Behavior and Emotional Contagion

Birds exhibit emotional contagion; if one bird takes flight, others follow without fully assessing the threat.
Research by Marc and students observed western evening grosbeaks.
Grosbeaks in a circle showed better coordinated scanning behavior compared to those in a line.
Grosbeaks in a line exhibited higher anxiety levels and more frequent body/head position changes.
This difference suggests better information sharing and coordination within the circle formation.
Grosbeaks in a line had limited visibility of the flock, hindering emotional contagion compared to the circular formation.
