Related Species

Cocos Cuckoo was formerly considered a subspecies of Mangrove Cuckoo (Coccyzus minor) by some authors (e.g., 9). Phylogenetic analysis of mitochondrial DNA sequence data suggests that Cocos Cuckoo is sister to Mangrove Cuckoo, and that the two are closely related (10). Together, Cocos and Mangrove cuckoos appear to be sister to Pearly-breasted Cuckoo (C. euleri) and Yellow-billed Cuckoo (C. americanus) with strong support (10). In another study where Cocos Cuckoo was considered conspecific with Mangrove Cuckoo (11), Mangrove Cuckoo was found to be sister to both Pearly-breasted and Yellow-billed cuckoos, supporting the results found in Sorenson and Payne (10).
