Marshall, 1945 Palau Otus podarginus. strip from base to top of ridge & the added luxury of a few chosen song perches out in the poplars within 100 yds base of ridge. Do not respond to imitated hoots unless in middle of terr (usually inaccessible) & then only come overhead for short while. Sometimes can decoy a & by giving typical & call at end of his calls but he usually overshoots you, and altho goes over you, doesn't land near. Only once did I decoy a bird into view. Largest Abundance terr are where jungle & lagoon meet - pair will have a circuit of song trees going thru both habitats - still about 100 yd rad. Abundance: As indicated - pair per 100 yds ridge. Night of 19 Nov - moonlight - hiked back from lake to end of main ridge & in valleys & ridges heard about 15-1 pairs - Anyway very common always within hearing of several pairs. (calls on the small Koror ridge, where not so many do.) estimate 6 pairs on NE slope, 6 on the opposite, 5 or 6 more pr in surrounding lagoon. About 4 pair in woods at Pelelin. (Absent from the blasted, vine-grown parts of the island). Time of activity: Certain pairs make one series of hoots shortly after sunset,
