Table 1. Details of satellite tag deployment duration and movement of six individuals for which migratory movements from coastal calving grounds were obtained.

A state-space model framework was used to classify two behavioural modes based on mean turning angles and autocorrelation in speed and direction: travel and Area Restricted Search (ARS). Data on speed for each behavioural mode, and total duration of ARS behaviour for each individual whale are summarised below.

Tag ID	Age class—Sex	Deployment location	Deployment date	Duty cycle	Tracking duration (days)	Track distance (km)	Distance (km) / hour (mean ± sd; range)		Distance (km) / day (mean ± sd; range)	ARS behaviour duration (days) Estimated / Uncertain
