Ludwig, James P. 1964 5 head preening (mutual) with little or no vocalization. To bed at 2300 very tired and frustrated. March 28--Up at 0615. No evidence of the dark-rumps at this hour.' However, we did hear many Pheasant, Chuckors and Zosterops; Zosterops ran up the crater walls behind Kapalalga to at least 8000 feet. On the trail at 0700 down to Paliku we noted 8 Chakars, one pheasant, and at the AA lava flow we saw the first skylark. Down the Palihu trail we noted more pheasants, chuckars, and many skylarks. At Palihu by 0820. We noted Amakiki, heard Iiwi, and Apapane, but nothing else of Drepanididae, Zosterops and Leiobrix were present. Hiking up from Paliku at 0905 we noted a flock of nine Golden Plover at 6700 feet, Ricebirds at 6,800 and 6,900 feet. Pheasants were particularly common between the 6600 and 7300 foot levels; Chuckar were also seen. At 6900 to 7300 foot between the 2 AA lava flows at this end of the crater is an extended ecological island made up of scrub (relative of Keawe ?) bushes bearing a yellow flower. Here we noted skylarks as very common and also saw six singing Mockingbirds. From the 7300 foot level saw where the floor of the crater becomes a plateau there is practically no avian life: However, there is a small ecological island on the southeast crater rim and skylarks were heard there. Many of the edges of the crater appear suitable for Dark-rumped Petrel nesting. The only way to investigate this properly is to hike the rim, not the floor.
