Study Notes

Bird Behavior and Emotional Contagion

Birds exhibit emotional contagion; if one bird flees, others follow without evaluating the threat.
Research on western evening grosbeaks shows that birds in a circle scan more coordinately than those in a line.
Birds in a line show less coordinated scanning and more nervous behavior, adjusting their body and head positions more frequently.
Grosbeaks in a circle can see each other, promoting better coordination. Grosbeaks in a line only see their immediate neighbor.
Lack of visibility of the whole flock in a line might make birds more fearful, because they do not know what their flockmates are doing.
Emotional contagion is limited in a linear array to only nearest neighbors.
