Juvenile largemouth bass were tested for manifestations of sun‐compass orientation. Fish captured from opposite sides of a pond were tested in a circular pool on clear days and on overcast days. When released from the center of the pool on clear days, the fish swam to the wall of the pool in the compass direction that would have taken them to deep water in the pond from which they had been captured the morning of the test. On overcast days the behavior of the fish from one side of the pond was not significantly different from those from the opposite side of the pond.
