Aggregation size of Bryde’s whales was positively correlated
with the occurrence of feeding behaviour in this study. This
was similar to the situation in the Gulf of California, where
solitary individuals were usually travelling, whereas aggregations
of comparable sizes to those found in this study during
summer and autumn were associated with feeding . During winter there are increased sightings of Bryde’s
whales farther north along the East Coast, frequently in
groups with common dolphins and Cape gannets .
