Causes of Mortality

Cats and rats introduced by humans to Isla del Coco prey on the cuckoo (16, 1).

Population Status

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.
