Diving behaviour of the Australian Coot in a New Zealand lake | Notornis and Birds New Zealand

[摘要] In a 1-day study of the Australian Coot (Fulica atra australis), the duration of dives increased with increasing depth, although the frequency of diving remained relatively constant. Duration and frequency of dives at given depths appeared not to vary with age. However, aggressive adults often drove young birds into deeper water. The duration of dives changed with the time of day, the birds preferring to dive in direct sunlight.
