Abstract

We performed Exploratory Data Analysis on data sets assembled to determine subspecies limits of great horned owls (Bubo virginianus) in Texas; the results revealed unusual patterns of tail measurements. In the subspecies B. v. pallescens, tail lengths of males (206.0 mm) were longer than those of females (202.5 mm). Additionally, tail length was longer in intergrades (males = 209.4, females = 213.5) than for either subspecies (B. v. virginianus males = 206.2, females = 209.0; B. v. pallescens males = 206.0, females = 202.5).
