From: Prey ingestion rates revealed by back-mounted accelerometers in Eurasian spoonbills
Foraging spoonbill equipped with a GPS/ACC tracker along with representative acceleration data patterns. The arrows indicate the three directions in which acceleration is measured by the tracker. On the right panel, representative acceleration data patterns (at 20 Hz) for the most relevant behavioural classes, with the bottom right panel representing foraging behaviour, including both searching for and ingesting a prey (the shaded area).
