(''Himantopus novaezelandiae''). It feeds largely on aquatic insects and on small molluscs. It emits a repeated yelping cry as it flies, and the legs trail behind it, tending to sway from side-to-side. The pied stilt breeds in spring, choosing as a nesting site an area of sand or shingle by an

'') flourishes. It prepares a nest in a shallow depression or in a scrape in the ground where it usually lays four, ovoido-conical eggs. These are yellowish-brown dappled irregularly with dark blotches and spots. The nest is difficult to find as the eggs are well-camouflaged. But the parent birds give away the presence of the nest by mounting into the air and flying in circles, uttering distress cries. The chicks are able to leave the nest almost as soon as they have hatched. They are difficult to detect because their downy plumage is well-camouflaged and they "freeze" when alarmed. A parent bird sometimes feigns a leg injury to draw intruders away from its chicks.
