Reduced numbers in the 1960s and 1970s may have been due to pesticide use or to peaks in commercial cinnamon cultivation and logging (which reduced upland forest to its lowest extent at this time)6. Introduced nest predators, nest-site competitors and food competitors may be an ongoing threat1,8,10. Housing development could be a threat4, although the species breeds in urban areas6. Fires, and possibly housing developments and alien predators, have nearly halved its population on Praslin in 10 years3,12.
