Abstract

During 1959-1969, grey teal (Anas gibberifrons gracilis Buller) utilized saltwater habitat in north Queensland mainly for feeding purposes during the frequent prolonged periods of low rainfall. The diet of these non-breeding predominantly adult birds changed seasonally, according to availability of foods, from brackish-water material (mostly plant seeds) to marine organisms (mainly molluscs). This change was effected by birds moving down rivers through marginal saltpans to confluent estuary tidal flats and thence to open bays. In these circumstances there was an abundant suitable food supply in the dry season and birds remained in good condition.
