tarapunga - red-billled gull - Larus novaehollandiae
This series of shots shows an adult gull (with the red bill and feet) clearly trying to wean its youngster. The juvenile bird (with its speckled feathers and black bill and legs) was constantly harassing the adult begging for food. Clearly the adult thought it was time the youngster found food for itself. It alternatively threatened and used barrier postures toward the younger bird and also tried flying away only to be pursued by the other. The adult eventually got quite aggressive but even then the youngster persisted in begging, to no avail.
