Breeding

Introduction

Breeding of Rufous-winged Ground-Cuckoo is very poorly known. Apparently is not brood parasitic, as a newly fledged juvenile was collected at the same ant mound where an adult male and adult female (presumed pair) had been collected only a few days earlier (Payne 2005); furthermore, no other species of Neomorphus is known to be a brood parasite (Payne 2005).

Time of breeding is very poorly known. Female with large ova (6 x 5 mm) found in September in Guyana. Newly-fledged young collected on the Siparuni River in Guyana in March (Payne 2005). Male with enlarged testes found in March in southern Venezuela (Chapman 1914).

Nest unknown.

Incubation period unknown. Eggs are yellowish-white with small bulges on the surface. Mean size 40.1 x 30.8 mm; range 37.1-41.5 mm x 29.2-32.0 mm (n = 8; Schönwetter 1967).
