Threats
The coastal breeding site of the African black oystercatcher makes it vulnerable to human disturbance, particularly as the breeding season coincides with the height of the summer tourist season. Eggs and chicks are crushed by people or off-road vehicles, or eaten by domestic dogs (5). Coastal development has also caused populations to decline in some areas (2). As the African black oystercatcher forages exclusively in the intertidal zone, it has a limited time to obtain the food it requires before the tide comes in. Disturbance during this period may result in birds having insufficient time to obtain enough food for themselves and their young (5). African black oystercatchers breeding on islands are less vulnerable to human disturbance; instead the major threat to these populations is the introduction of terrestrial mammalian predators (2) (7).
Conservation
The Oystercatcher Conservation Programme, launched in 1998, undertakes research on the African black oystercatcher and aims to develop a conservation strategy for the African black oystercatcher (8). In addition, this bird is listed on Appendix II of the African-Eurasian Waterbird Agreement, which calls on parties to the agreement to engage in a wide range of conservation actions (3).
