A low-pressure system was developing off the coast resulting in a humid summer day with poor visibility and a large swell. Erratic oceanic currents constrained our navigational options and prevented us from drifting to attract birds.
The usual summer collection of shearwaters and jeagers were apparent with Flesh-footed Shearwaters being present in unusually high numbers. Petrel numbers were disappointing but we were rewarded with great views of a WHITE-NECKED PETREL several kilometres from the coast on our return trip.
A WHITE-NECKED PETREL and a LONG-TAILED JEAGER were identified amidst large numbers of the usual summer seabird species.
