- Species that provide intensive parental care could suffer fitness costs associated with conspecific brood parasitism. Here we evaluate the effect of conspecific brood parasitism on apparent annual survival probability of female Prothonotary Warblers Protonotaria citrea using a multistate model with imperfect state assignment analysed in a hierarchical Bayesian framework. We found no difference in annual survival probability between host and non‐host females. These findings agree with previous work in that there seems to be little apparent cost of conspecific brood parasitism to female Warblers in this system.
