Marshall, 1945 Palau Ptilinopus purpureus of roseicapillus by its occasional hesitations* and the absence of a speed-up to a roll in the middle of the sequence: coo, coo, coo, coo-cu*, coo, coo-cu, (now descending in pitch) cu, cu, cu, cu, cu. All the notes are of same quality, and inflection (none of the rising inflection in terminal notes that rosei has). All have downward inflection: These calls are heard all day and night. The first night on Koror I had a bad time figuring out the owl and goatsucker's calls because of these doves, which I certainly didn't expect to hear. One will call them all the birds, roosting in that neighborhood will take it up in turn or in choruses! Each (i.e. one full sequence) calls only once. I could start them off at night by giving imitated call. I didn't see any hang & flutter on small twigs the way Quails does. Eat the fruit whole. Flight keeps t-level of treetops. You hear dozens for each one seen. All islands. Mostly natural timber but spills out into settled areas where big trees.
