12 September: Caretaker first bird heading south

Our study has over the past few weeks suffered increasingly from depleted batteries, and all transmitters stopped collecting GPS locations. We thus only recieve doppler-data every third day, when the transmitters uplink to the satellites. Fortunately Caretaker flew south over the Barents Sea on such a day, and the upper part of the map shows his flight from Svalbard to Lofoten on 9 September. The lower part shows his further movements on 10-12 September, when the transmitter resumed collecting GPS locations.
