There was an error published in J. Exp. Biol.209, 1617-1629.

In Fig. 6 of this paper, the y-axis label was incorrect. It should have read:

POR's velocity heading φ (deg.).

The correctly labelled figure is reproduced below.FIG1 

Fig. 6.

Relationship between stride-averaged φ and θ. Each data point consists of the averaged φ and θ values during a stride. We analyzed 1079 strides observed in 59 trials from 11 individuals. The best fit line (solid line) and the model, φ=θ (broken line), are both shown.
