High Quality Content by WIKIPEDIA articles! Stilts and avocets breed on open ground near water, often in loose colonies. They defend nesting territories vigorously with aggressive displays and mob intruders and possible predators with a great deal of noise. They are monogamous, although the pair bonds are not maintained from season to season. Their eggs are light-coloured with dark markings, weighing 22 to 44 grams. Three to four are laid in simple nests, and both parents share the incubation duties, which last 22 to 28 days. The Banded Stilt may breed only every couple of years, as it breeds on temporary lakes caused by rains in the deserts of Australia. The chicks are downy and precocial, leaving the nest within a day of hatching; they fledge in 28 to 35 days. In all species except the Banded Stilt, the chicks are cared for several months by the parents, which may move them to new areas and defend territories there; Banded Stilts deviate from this by collecting their chicks in massive creches numbering several hundred.
