Eggs (Guide)
2 -3; pale blue-white, spotted and speckled with brown and grey, particularly at the larger end; oval; about 27 x 18 mm. Incubation: about 18 days; by female only.
Young
Altricial, nidicolous. Fledge in about 17 - 19 days.
Subspecies
Taxonomy highly complex. Subspecies group into four morphological types, but attempts to "tease out" taxa or groups as separate species largely frustrated by irregular distributions of taxa with allied characters. Highly distinctive Taiwanese subspecies niveiceps, although clearly allied to present species, possibly best candidate for species status, being the only subspecies with pronounced sexual dimorphism, and much the most northern outlier.
Proposed subspecies biesenbachi (from Mount Papandajan, in western Java) considered not reliably distinguishable from fumidus. Two additional populations, as yet undescribed, apparently exist in central and eastern Sulawesi. Subspecies mareensis (Maré, in Loyalty Is) and vinitinctus (Lord Howe I) extinct.
The following 54 subspecies are recognised:
