Never mind this bird's journey. The most surprising thing about this is that they apparently have GPS trackers that are small and light enough to attach to a bird and have long enough battery life to be able to track them over longer periods of time.
I assume they don't catch the bird on a daily basis to replace the batteries.
- tim333 3y agoYeah. Some info >GPS loggers (13–14 g, 2–3% of body mass; PinPoint VHF-GPS, LOTEK) were attached to the back feathers using waterproof tape (Tesa). The loggers were set to record the geographic position every 15 min and send data via radio communication to the receiver placed within the breeding colony when birds returned from the sea. The tracking duration of the birds ranged from 8.9 to 34.2 days (mean ± S.D.: 24.8 ± 6.8 days).
