Genetic mating system of three colonially breeding waterbirds inferred by reconstructed kinship patterns among nestmates. Proportions of pairs classified as either full-siblings (FS), half-siblings (HS) or unrelated (UR) relative to the total number of Wood Stork, Roseate Spoonbill, and Great Egret nestlings-pairs sampled inside nests in breeding colonies from Amapa state, Pantanal Region and Rio Grande do Sul state (Brazil). Observed kinship pairs in our sample are shown for each species. Relationships were identified using the procedure outlined in figure 2 and reported in Tables S6-S12. Inferred genetic mating system and degree of parental care are also indicated.
