Inferred genetic mating system of the cattle egret.

Inferences drew using the parental allocation approach with samples from incubating adults or the multiple methods’ approach in absence of parental information. Inferred genetic mating system (i. e., monogamy, CBP: conspecific brood parasitism, or EPP: extra-pair paternity) refers to whole nests rather than dyads. Symbol ‘/’ indicates that both behaviors were detected in nest. ‘Not inferred’ (nest #16) indicates that the multiple methods approach could not reach a final diagnosis for the full brood. Detailed results of parentage and kinship analyses for all nests are given in Tables C and D in S1 File, respectively.
