Each checklist can be viewed with photos shared by the birding community, and also printed as PDF checklists for field use. However, the difference in predation rate among the three environments was not significant, predation was the main cause of nests loss and it should be considered as an important cwcicus supporting a higher breeding success and number of nests in the swamp environment.

Nest containing dead nestling with signs of aggression, such as injuries and beak marks, were also considered predated.
