Which taxonomic group is more likely to lose feathers as a sign of severe stress?

The taxonomic group that is more likely to lose feathers as a sign of severe stress is indeed the group commonly comprised of doves and pigeons, known as Columbiformes. Feather-loss, or stress-induced feather plucking, is a behavioral response seen in these birds, often triggered by factors such as environmental stressors or social challenges. In many cases, this feather loss can be exacerbated by inadequate living conditions, changes in their environment, or even separation from their flock or companions.

This phenomenon aligns with the behavioral traits exhibited by Columbiformes. They can be particularly sensitive to their surroundings and any disturbances they perceive. This sensitivity often makes them more susceptible to stress-induced feather loss than other taxa.

The other groups listed, such as Strigiformes (owls), Psittacines (parrots), and Anseriformes (ducks and geese), exhibit different stress responses. While they can also experience stress-induced behaviors, feather loss is not typically a prominent sign in these groups. For instance, psittacines may show aggression or other abnormal behaviors when stressed, while strigiformes tend to be solitary and might not display any visible signs of stress until it becomes severe, and anseriformes are more
