The present paper reviews the published information on mating systems and reproductive biology of Neotropical waterbirds. Thirty-four scientific articles were included, which divided into two main themes: “mating systems” (10 articles) “reproductive biology” (24 articles). Extra-pair copulation and/or fertilization reported to occur in 60% species investigated, while monogamy was 22%, bigamy 11% nest parasitism 11%. General aspects 30 more extensively reviewed, 20 seabirds 10 lacustrine species. Aspects most frequently described chronology (73% species), clutch size (80%) success defined by number hatched eggs (73%). Only one Sulidae (Sula leucogaster) Threskiornithidae (Eudocimus rubber) studied for both, system reproduction. A global analysis available data revealed that Ciconiiformes birds intensively terms biology, their remain largely uninvestigated.
