how many eggs do they lay?
Four eggs
American avocet
Nesting takes place near water, usually on small islands or mucky shorelines where access by predators is difficult. Together, the male and female build a saucer-shaped nest, take turns incubating the four eggs, and tending to the precocial young.

American avocet [SEP] Breeding
American avocets breed in anything from freshwater to hypersaline wetlands in the western and mid-west United States. American avocets form breeding colonies numbering in dozens of pairs. Throughout the breeding season, birds pair off in a series of copulatory displays. After breeding, the birds gather in large flocks, sometimes amounting to hundreds of birds. Nesting takes place near water, usually on small islands or mucky shorelines where access by predators is difficult. Together, the male and female build a saucer-shaped nest, take turns incubating the four eggs, and tending to the precocial young. Upon hatching, the chicks feed themselves; they are never fed by their parents.
