| Birds that bring up young cuckoos are unable to distinguish between parasitic nestlings and their own. |
| Her data supported a tree topology in which Coccyzus is nested within a single clade comprising all of the parasitic cuckoos. |
| As has been shown for other bird taxa, smaller species of cuckoos and hosts lay relatively larger eggs in proportion to their body mass. |
| The wet season is hot and humid and the best time for flowering plants, amphibians, reptiles and intra-African migrant birds such as cuckoos. |
