This observational analysis describes bird abundance and behaviour in the Bay of Plenty, suggesting insights into seasonal migrations.
The seasonal patterns of the abundance of petrels and other birds at sea in the western Bay of Plenty, as observed in 1968 and 1969, are described and correlated with the existing data on breeding places and seasons. Inferences on seasonal migrations and on the feeding range of several species are drawn, and flocking and feeding behaviour are described.
