Rufous-vented or Scaled Ground-Cuckoo
Neomorphus [geoffroyi or squamiger] (= Neomorphus geoffroyi) (Temminck, CJ 1820)
The rufous-vented ground cuckoo is a large terrestrial species of cuckoo in the family Cuculidae. It is found in humid primary forests from southern Nicaragua, through Costa Rica and Panama, into north-western Colombia. Another population occurs in the western and southern Amazon Basin of south-eastern Colombia, eastern Ecuador, eastern Peru, northern Bolivia and Brazil, while a final population occurs in the Atlantic Forest of eastern Brazil. Much confusion exists over the exact limits of its distribution in the south-central Amazon, where the very similar scaled ground cuckoo occurs. Consequently, the scaled ground cuckoo has often been considered a subspecies of the rufous-vented ground cuckoo. Source: Wikipedia
