Families Musophagidae Cuculidae Opisthocomidae The near passerine bird order Cuculiformes traditionally included three families as below: Order Cuculiformes Family Musophagidae: turacos and allies Family Cuculidae: cuckoos Family Opisthocomidae: Hoatzin However, the taxonomy of this group is now controversial. ...
Among the anis, there is considerable variation in nesting habits. One species, The greater ani C. major lays 2 or 3 eggs, while the groove-billed ani C. sulcirostris lays seven. However the smooth-billed ani C. ani will share one nest between several females, with up to 29 eggs in one nest! Incubation takes 15 days for this species. The nesting habits of the guira cuckoo are unknown.

The Hoatzin aside (which has a separate page on this web site), the only question is how many families to create out of the diversity in the Cuculiformes.
Sibley and Monroe (1990), followed by Clements (1991), settled on five families: the Old World cuckoos (Cuculidae) in which they included the malkohas and couas; the coucals (Centropodidae); the American cuckoos (Coccyzidae); the roadrunners and ground-cuckoos (Neomorphidae); and the anis and Guira Cuckoo (Crotophagidae).
The second grouping (subfamily in this arrangement) of New World cuckoos are the anis and allies (Sibley and Monroe's "Crotophagidae").
