Feeding habits

Large invertebrates and insects.


Although this species may have a restricted range, it is not believed to approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
At one time quite common, the Palau Owl became increasingly rare between World War II and the 1960s. Ecologists suspected that the decline was due to the rhinoceros beetles ingested by the owls. A concentrated effort was made to rid the islands of the fatal beetles, and it was observed that as this scourge was brought under control, the owls began to increase in number.
