Demographic traits largely undescribed, as are limiting factors. The age at first breeding, annual and lifetime reproductive success, and life span are all unknown. Sources of mortality are unknown. Has been documented among the fatalities at the La Venta II wind farm in Oaxaca, Mexico (Herrera-Alsina et al. 2013) and as roadkill in Everglades National Park, Florida (Robertson 1978). No information exists on natal dispersal or on fidelity to breeding site or winter home range. In mangrove forests of Florida, radio-tagged Mangrove Cuckoos occupied fairly large home ranges during the breeding season (average: 20.0 ha; range: 6.7 – 36.2 ha; n = 7) (J.D. Lloyd, unpublished data).
