banded dotterel

Breeding success and predation at nests of banded dotterel (Charadrius bicinctus) on braided riverbeds in the Central South Island, New Zealand

Egg and chick loss at banded dotterel (Charadrius bicinctus) nests was studied over the 1992/93 season on the Tekapo, Ohau and Ahuriri Rivers in the Central South Island. Egg loss at nests was higher on the Ohau and Tekapo Rivers than on the Ahuriri River, especially early in the season. Only 11% and 12% of nests fledged one or more chicks on the Tekapo and Ohau Rivers respectively, compared to 42% of nests on the Ahuriri River. Nests on islands within the braided riverbeds were more successful than nests on the mainland.
