nest is a platform of twigs lined with lichens placed on a horizontal branch between about above the ground and concealed by foliage. The clutch size is two to five eggs. Both parents incubate the eggs over nine to 12 days and fledging occurs eight to 13 days after hatch. Incubation begins with the first egg laid so hatching is asynchronous and the young differ in size. Vocalization The grey-capped cuckoo's song is a "[f]ast series of 6–8 hollow and falling 'cu' notes, often with a slight pause before the last note, e.g., 'cucucucucu­cucu-cu'." It may be repeated several times during each song bout. Status The IUCN has assessed the grey-capped cuckoo as being of Least Concern, though its population size is not known and is believed to be decreasing. No specific threats have been identified. Its distribution is not well known; it is thought to be fairly common but still local in western Ecuador and rare elsewhere. "Further research [is] required, primarily to define [the] limits of range."
