OBTAINED STATISTICALLY RELIABLE DOMINANCE ORDERS WITH THE "WEDGE" TECHNIQUE, A MEASURE BASED ON COMPETITIVE FEEDING, WHICH CORRELATED POSITIVELY AND SIGNIFICANTLY WITH ORDERS OBTAINED BY THE OBSERVATION OF AGGRESSIVE BEHAVIOR. AMONG FLOCKS THAT HAD BEEN IN EXISTENCE FOR AT LEAST 2 MO., FLOCK SIZE DID NOT PRODUCE DIFFERENCES IN THE RELIABILITY OF THE DOMINANCE ORDER, ALTHOUGH THE ORDERS IN LARGE FLOCKS MAY BE LESS RELIABLE DURING THE 1ST FEW WEEKS AFTER FLOCK FORMATION. RELIABILITY OF THE DOMINANCE ORDER WAS NOT AFFECTED BY THE LEVEL OF DEPRIVATION UNDER WHICH SS WERE OBSERVED NOR BY CHANGES IN THE LEVEL OF DEPRIVATION DURING TESTING; RELIABILITY INCREASED WITH INCREASING AGE OR AMOUNT OF SOCIAL EXPERIENCE WITH OTHER BIRDS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
