Each of three hand raised crows received 300 learning set problems in a modified WGTA using three-dimensional stimuli. Consistent within-problem learning was obtained but learning set formation was minimal. An analysis of hypothesis behavior (Levine, 1959) revealed a strong tendency towards position and stimulus preferences. These results raise the possibility of large species differences in learning set formation within the family Corvidae.
