A male black-faced spoonbill woos his partner before the pair begins matching. The male bird strokes the female f s cheek, head and neck with his beak. The wooed responds to him by doing the same. The foreplay continues for four to five minutes before they start coupling which last seven to eight minutes. The wooing and matching are repeated during the bed-making period, and ends after the female bears her first egg and starts hatching.
Parents repair and reinforce their nest nearly everyday during the hatching and raising period.
The male parent is in charge of gathering woody material while the female parent of building and reforming the shelter. The reshaping of the nest is believed to be aimed at preventing the eggs and young from falling, and showing how to build a nest to their young. Its white egg is oval with a chestnut dot pattern. The female starts laying the first eggs at the end of May. She delivers the second two days later.
