That the juveniles were recently fledged is further supported by the soft rhamphotheca of both juvenile specimens, a characteristic of a very young bird (Mees 1964).

Relationships Relationships within Aplonis are complex and confusing, with morphological variation and former distribution difficult to determine. Aplonis starling distribution appears to represent complex pulses of range expansion, colonization and probable extinction, sometimes resulting in isolated or sympatric populations. In the Kosrae Starling, differences from other members of its family in diet, bill shape, and distinctiveness of juvenile/adult plumage suggest suggest specialisations indicative of prolonged Figure 4.
