Causes of Mortality
Cocos Cuckoo is the species with the lowest population density (0.23 ± 0.08 ind./ha, IC: 0.12 –0.44) of the endemic birds of Isla del Coco (16). However, more specific studies on the population status of the species are required to better understand its population density (1); the total population may be larger than suggested, due to the stealthy behavior of tis species.
