Marshall, 1945 26. Palau Cuculus Koror 3 Nov One flew into tree at 3rd B.H.Q. Seemed to be slate-blue above barred black & white below with chestnut or rufous color somewhere - apparently on throat or chest. Narrow-pointed wings, long tail, rapid straight flight. Seen several evenings in succession while I was hunting bats at N edge ridge. It would fly along top of ridge & enter a tree on the top. A few min. later would dash on & disappear over the ridge. Must have roosted up there. Otus podarginus (Podargus) Koror & Peleliu Habitat: Same as Ptiliogynus (a) Natural jungle (ridges on Koror, intact patch of forest near Purple Beach, Peleliu), (b) "Poplar" trees in forested mangrove lagoons - these trees 30-50 ft high & form an open forest, mangroves & water beneath, or mud flats. Individual pairs or single will based in the natural habitat (i.e. regular territories) will sally out into adjacent cultivated land where there are clumps of trees & will call from Palms, Bamboo, etc but stay within 100 yds of the natural forage terr. In many cases the pairs in the "poplar" lagoons are roving from a base in jungle on the ridge, but some pairs call before they roam way out
