Marshall, 1945 Palau Caprimulgus indicus Habitat: Same as Ptilinopus & Otus on Koror & Pelelin. (jungle & "poplars" of mangrove lagoon - or lagoons where there are large trees). Differ from Otus in larger forage area. In middle of night, individuals can be shined & induced to call in big trees in cultivated areas far from home habitat. More com. Prefers the dense jungle, however. Abundance: Not calling much at this season - some evenings hear none i. had to estimate, but seem to be spaced out about same as Otus, perhaps fewer, but do congregate 2, 3, or 4 together esp. in hugest trees. Not found in same place successive nights, wanders more. One night there were 5 or 6 about a huge tree on N ridge Koror (Ptilinopus tree). They were at the extreme top of it & were giving the incessant rolling notes (steady - no let-up or pause for minutes at a time). Usually found singly & rarely call. Most calls are given in flight - more almost always " " " . "Hammer-beat call" given stationary - low tree, top part of trees or (1) on stake or 1 ft from gnd. Indic. shined at night rarely because hawk about in dense foliage.
