Marshall, 1945 Palau Psamathia annae sounds very much like Chrysothorus modestus. During daylight usually only the whistle. This is eerie and uncanny - a very full penetrating tone but not loud. Generally swells in middle or tapers off which enhances the eerie quality. A sedentary bird. A J spends hours singing from one vine clump. Seldom seen in flight. Rarely see the small foraging groups mentioned above - 3 or 4 birds together. Usually solitary, but most will be stationed a few yards away (Pelelin). Not very active - hop about in vines about like solitary vireos or wrens. Not seen on ground. Rhipidura rufifrons All islands. Common, but less so than Saipan & Tinian. Restricted to native heavy jungle growth where forage in bushes & vines of understory, only occasionally going into middle parts of large trees. Pairs general, or else an ad & 1 or 2 im together, or 2 or 3 im together. (No song heard (see Saipan & Tinian)). Call notes entirely different from Marianas - louder & harsh scolding, raven-like notes after a succession of down-inf syll. at same rate.
