Eight nestlings of Grey Heron were captured in the Peter the Great Bay, Primorskii Territory, Russia and were deployed with trackers supporting GPS and Mobile Phone in May 2017. In total, 35,166 records on the locations of the birds were obtained over the study period until November 18, 2019. The tracking data were available for seven birds in autumn 2017, three birds from spring to autumn 2018, two birds in spring 2019, and only a single bird in autumn 2019. We could trace the migration routes accurately and locate the places for feeding and resting of the Grey Heron during the post-nesting period and seasonal migrations. The direction of the migration of the Grey Herons in autumn was southwest, and it was northeast in spring without exception. With tracking data, we found that there were two main patterns of migration of the Grey Heron: fast and delayed migration. The Grey Heron has been frequently reported to be affected by highly pathogenic avian influenza, and thus, a possibility that infected Grey Heron delivers avian influenza virus in East Asia had been discussed.
