Crested Grebe Nests in Queenstown Bay

In September the Whakatipu Wildlife Trust installed 3 Nesting platforms in Queenstown Bay.

Crested Grebe are a rather rare and unusual species of water bird that is barely able to walk on land. It creates floating nests made of weeds and sticks. Nests are attached to underwater debris, but when lake levels change, nests can be lost.

Some of the birds in Queenstown have found an interesting floating alternative. It’s on the back of boat engines that are partly underwater (mostly Jet Boats) that are anchored on the lake. Clearly a risky choice, so we are helping with the conservation of this species by building floating platforms on which they can build their nests. We also help them by building the nest.

Breeding takes place October to February. Three to four eggs are laid and incubated for 24-26 days. As soon as all the eggs are hatched, birds leave the nest with the chicks on the backs of the parent birds. They will be piggy-backed for the first two to three weeks and then swim freely and feed with the parents for about 3-4 months.
