Correction to: Nature Ecology & Evolution https://doi.org/10.1038/s41559-020-1094-9, published online 3 February 2020.

In the version of this Article originally published, in Fig. 1, the colour legend in the middle-left panel was incorrect. ‘Dorsiflexion’ was originally labelled red but should have been grey; ‘Lateroflexion’ was originally labelled blue but should have been green; ‘Ventroflexion’ was originally labelled green but should have been orange. This has now been corrected.
