Biology

Life span is on average 7.7 years (3), although the oldest recorded individual reached the age of 28 (2). The breeding season runs from October to March (4) and females start breeding from three years old (2). Nests are built in scrapes on the ground and two to three eggs are laid (2). The nests tend to be positioned on the shore away from the waterline, amongst low vegetation (3), or under an overhanging rock on the cliff edge (4). Individuals are territorial throughout the year (4). The principal diet is made up of marine molluscs, worms and other invertebrates (3), which are prized from the rocks by the thick bill (4). Feeding on the rocky shore, oystercatchers have also been observed to feed on the anemone Isactina tenebrosa (4).
