Very little is known about the reproductive biology of Rufous-necked Wood-Rail, apart from the observations by Belcher and Smooker (1935). Belcher and Smooker (1935) report nests from July and October in Trinidad, and down young were observed in Peru in February (Parker et al. 1995). Belcher and Smooker (1935) describe the nest as "an open bowl of small twigs, lined with weed-stems, deald leaves, and, finally with green bamboo-leaves". Nest sites are in a small tree and on a stump, 2-3 m above the ground. The clutches of two nests were five; the eggs are cream, marked with rust brownl light brown, and purple spots and blotches. Mean egg dimensions (from a single clutch) are 47 x 33 mm.
