Scaled ground cuckoo
The scaled ground cuckoo (''Neomorphus squamiger'') is a species of cuckoo in the family Cuculidae.
It is endemic to the Amazon rainforest near the Tapajos River in Brazil, but much confusion exists over the exact limits of its range and the features useful for separating it from the very similar rufous-vented ground cuckoo (the breast-markings of the Amazonian taxa are known to vary clinally). Consequently, it has sometimes been considered a subspecies of the rufous-vented ground cuckoo.
==Description==
The scaled ground cuckoo is a large ground-dwelling bird with sturdy legs and a long tail. It has a brown head, greenish-brown crest and a curved beak. The upper parts are dark brown, the tail blackish and the underparts pale tan. It has been claimed that it easily can be separated from the rufous-vented ground cuckoo by the lack of a dark chest band, but the variation in this feature in Amazonian rufous-vented ground cuckoos makes the features questionable. As a consequence, recent authorities commonly treat the scaled ground cuckoo as a subspecies of the rufous-vented ground cuckoo.〔Erritzøe, Mann, Brammer and Fuller (2012). Cuckoos of the World.
