Unconditioned aggression in the Japanese quail, Coturnix coturnix japonica

Abstract

Isolate, social, and social-isolate quail were paired to observe fighting, pecking, jumping and vocalization. Data showed a direct relationship between isolation and aggression. Slightly more consistent pecking was also recorded from the isolate birds. Jumping behavior was also directly related to social and social-isolate rearing conditions. Aggressive vocalization was observed in only two of the isolated birds. © 1968, Psychonomic Journals. All rights reserved.
