We present design specifications for a self-contained activity recorder, developed for use on plunge-diving seabirds. Compressed integrated circuitry and miniature components allow construction of recorders small enough (28 g) to be mounted on the tails of boobies and other seabirds. The cost is moderate. Field tests of the recorder on Brown Boobies (Sula leucogaster) demonstrated its ability to measure foraging behavior at sea that typically cannot be observed directly.
