Summary: | The migration route of R ed‐necked P halarope populations breeding on N orth A tlantic islands has been subject to considerable speculation. Geolocator tags were fitted to nine R ed‐necked P halaropes breeding in northern S cotland to assess whether they migrated to P alaearctic or N earctic wintering grounds. Of four birds known to return, two had retained their tags, of which one was recaptured. This male P halarope left S hetland on 1 A ugust 2012 and crossed the A tlantic O cean to the L abrador S ea off eastern C anada in 6 days, then moved south to reach F lorida during S eptember, crossed the G ulf of M exico into the P acific O cean and reached an area between the G alapagos I slands and the S outh A merican coast by mid‐ O ctober, where it remained until the end of A pril, returning by a similar route until the tag battery failed as the bird was crossing the A tlantic O cean. The total migration of 22 000 km is approximately 60% longer than the previously assumed route to the western part of the A rabian S ea, and this first evidence of migration of a E uropean breeding bird to the P acific O cean also helps to indicate the possible migratory route of the large autumn movements of R ed‐necked P halaropes down the east coast of N orth A merica. |
