Observations

Not much is known about the age at sexual maturity of this species. Females probably do not normally breed during their first year, although they may be capable of. Delayed plumage maturation suggests these animals are relatively long-lived when compared to other passerines. Although mortality was high among captive specimens due to numerous infections, one specimen was at least 12 years of age when it died at Honolulu Zoo [0445]. Oldest known banded individual was 9.7 years of age [0427].
