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.
