Introduction

The Blue-breasted Blue Flycatcher is an understory-dwelling flycatcher that is usually frustratingly hard to locate even within its preferred habitat. The species is restricted to low to mid-elevation rainforest habitats in northern and central Luzon, in the northern Philippines. Unobtrusive and fairly quiet, its local presence is perhaps most likely to be revealed by the species’ musical but fairly simple song, as well as its rather piercing and rattling calls. Males appear mainly rather dark blue in the dim light typical of their habitat, and females have a grayish head contrasting with a pale rufous throat. Both sexes have white bellies and appear rather big with large bills. Despite their rather striking different male plumages, Rufous-breasted Blue Flycatcher (Cyornis camarinensis) of southern Luzon was formerly considered a subspecies of the present species but differs markedly by exhibiting an orange rather than a blue breast. Very little is known of the biology of Cyornis herioti, which is a globally threatened endemic. The only nest reported in the literature was a moss-covered cup-shaped structure which held two eggs, sited in a rock crevice bordering a river.
