Lundberg (1986) has proposed that reversed sexual dimorphism (RSD) in owls has evolved as a result of selection for larger mass in females to resist starvation and shorter wings in males for more efficient foraging. His hypothesis is based on (1) a lack of correlation between RSD in weight and RSD in wing in European owls, (2) a correlation between RSD in weight and mean breeding latitude of a species and (3) a correlation between RSD in wing and the incidence of birds in the diet. I examine another four samples of weight and wing measurements and another two samples of diet for European owls, thus increasing the number of comparisons for a given relationship from one to as many as 15. Items (1) and (3) are supported by this analysis. Item (2) may be an artifact resulting from a correlation between insectivorous owls with low RSD that have southern distributions and owls that prey on vertebrates and have more northern distributions.
