The measurements of male and female Brown Creepers (Finschia novaeseelandiae) were compared to determine whether they are sexually dimorphic and, if so, which characters can be used to distinguish the sexes. In all the measured characters males were significantly larger than females. Possible selective advantages of the Brown Creeper’s sexual dimorphism are discussed. Wing length was found to be the most reliable discriminator of sex.
