Marshall, 1945 12. Palau Megapodius laperouse group, I noted that one bird will give the 3 cries simultaneously with the rolling cuk-cuk-cuk of a second bird. Koror & Due. Same ridge - this time in valleys of dense jungle out toward the lake. Heard several & shot at one. It was gone when I arrived at the place where it was shot. Found a lot of holes in the rock (made by #6 shot) and blood, but no bird! Here again I marvelled at the way these birds wall thru the rocks. From where I shot this bird looked as if it was walking along a straight line - perfect ease & steady movement as if walking along a little horizontal trail on the side of the ravine. When I reached the spot I found it was in some very jagged rocks - steep & with holes & tunnels everywhere. Same thing noted on calls - either part can be given alone, or both by 2 separate birds. Summary for Koror: Only on the
