Marshall, 1945 64. Palau Zosterops cinerea Abundant throughout - the most common bird wherever large trees occur - especially the heavy forest. Small flocks in open country - flocks of 25-50 in jungle. Drift thru tops of trees. Pairs or small groups everywhere also. In flight over mangroves, gardens, etc. Strong swift flight in open. Sometimes fly very high & for long distances - very different in this one respect from conspicillata. Also different in favoring the heavy forest & large trees. Otherwise they are just like conspicillata of Saipan with calls resembling it. Calls however sweeter than the latter, rougher & louder & lower pitched than Palau conspicillata. Cadence same. Curiosity - can decoy them very close with squeeks. They are very tame & very noisy. Forage in interior & crown foliage.
