African Black Oystercatcher Research Paper
GLENWOOD HOUSE THE AFRICAN BLACK OYSTERCATCHER WHAT IS THE ROLE OF THE AFRICAN BLACK OYSTERCATCHER IN THE NATURAL ENVIRONMENT? CHRISTAN BOTES MATRIC LIFE SCIENCES 2016 There has been a noticeable increase in the populations of African Black Oystercatchers (Haemotopus moquini) in the area of coast between Mossel Bay and Gouritzmond within the past 20 years. This is due to increased conservation efforts and the introduction of a new food source in the habitat of the Black Oystercatcher. The Oystercatcher plays an extremely important role of keeping the balance within the food cycle of a coastal environment and is very sensitive to human interference within a habitat. The local populations of African Black Oystercatchers suffered a great decline due to human interference, but due to conservation efforts the populations have recovered, and the re-established populations have assisted in bringing balance back to the local ecosystems and therefore play a vital role in coastal ecosystems.

They are shorebirds 42-45 cm in length, with black plumage and vividly coloured red legs, eyes and chisel-shaped beaks. They are monogamous, and live for 30-40 years; refusing to breed with another bird should their partner predecease them. They breed once in the months of summer in the Southern Hemisphere and do not breed again till the next season, provided that their first hatchling was successful. It is this slow breeding rate and the nature of their nesting habits that make the birds so vulnerable to human activity on the local beaches.

Red Knots: Article Analysis
589 Words | 3 PagesBy creating experimental beach scenarios, negative and standard, Karpanty, et al, increased and decreased the amount of surface eggs to compare the availability and sufficiency to refuel Red Knots in the Delaware Bay area.

Once that area was depleted, the Red Knots would move on to other horseshoe crab nesting areas.
