Abstract

he complacency—agitation continuum in Blackbirds was studied by recording their behavior in an observation cage. A scoring pattern with a reliability of 0.91 was developed. Cowbirds are the most complacent species and Starlings the most agitated. Grackles and Red-wings are intermediate. Individual differences within each species are demonstrated. It is probable that the trait under investigation is composed of a number of factors and that a factor analysis of several tests like the present one will throw light on avian personality structure
