KU departed its nesting area just one day later than KS. It first travelled 136km south to another area along the Verkhoyansk Range. After staying there for 14 days, it started migrating again on 2-Aug-17. Within 4.5 hours, KU has travelled more than 334km, which equals to an average speed of 74km/h!!!
