There was in error in the legend to Fig. 3. The published version reads:

Parameter functions for three gleaning echolocation call sequences of an individual M. septentrionalis. (A) Attack on non-arctiid moth; (B)attack on muted C. tenera; (C) attack on intact C. tenera. See Fig. 1 for further details.

The correct version should read:

Fig. 3. Parameter functions for three aerial hawking echolocation call sequences of an individual M. septentrionalis. (A) Attack on non-arctiid moth; (B) attack on muted C. tenera; (C) attack on intact C. tenera. See Fig. 1 for further details.
