The clutch consisted of 3 or less frequently two eggs (as opposed to some 5–10 for related continental rails). These were oval without being conspicuously more rounded on one end, measuring 31 x 21 mm and being pale olive buff in base color, irregularly marked all over in pale raw sienna or purplish grey. The sexes mated either for life or for an entire breeding season and shared incubation duties, although females seem to have spent more time incubating than males.
