21mar13, geolocator recovered, 207 days later







PagpKwa14597: Migration Variant:
This Kwajalein migration cycle changes to include a short Chukotka stop of 1 to 4 days northbound, and a diversion at the end of the southbound migration at Enewetak Atoll of duration 17days.

Flight weather southbound does not explain this diversion. Is it a navigation error? Why return to Kwajalein? Why not stay at Enewetak?






Route variability in Pluvialis fulva of Kwajalein Atoll:

Northbound routes are westerly, southbound routes are easterly. The circular migration takes advantage of favorable prevailing winds. The long oceanic flights have no indications of stops en  route.
