Specific objectives were to collect photo-point and ground-truthing data at Campbell and grey-headed albatross colonies, repeat whole-island counts of breeding Northern giant petrels, collect GLS trackers from Southern royal albatrosses, use sound recorders to record burrowing petrel distribution and check the bands of all banded birds seen. Adjusting chick counts to correct for breeding failures gave an estimated 150 (range 134–173) breeding pairs in 2019.
