 The eggshell is pure white, smooth and finely grained, without gloss, but with a salmon-pink tone produced by the contents.The eggs were described as 12 mm × 16 mm in size and oval in shape by Alfred North (1901–14); Forshaw gave the form as "ovate to elliptical ovate".A sample of forty six specimens from nine clutches were taken and noted as 15.9–17.8 mm × 11.9–13.2 mm to give average dimensions of 16.6 mm × 12.4 mm (Johnstone & Storr, 2004).
