Scientists Turn Birds Into Activity Trackers For The Sea
The discovery that the birds’ movements could be used to track the currents and tides came about when Cooper and his colleagues realized this valuable information was hiding in plain sight. When Cooper and his colleagues reviewed the RSPB’s data, they realized that the tracker-outfitted birds were indirectly measuring the tide and the surface currents. After filtering out tracking data of birds in flight, Cooper’s team compared the birds’ movements on the water to other tidal flow measurements, confirming that the two coincided closely.
