PRODUCTIVITY AND MOVEMENTS OF NENE IN THEKAIU DESERT, HAWAII VOLCANOES NATIONAL PARK,1981 - 1982*C.P. Stone, H. Hoshide, and P.C. BankoHawaii Volcanoes National ParkHawaii National Park, Hawaii 96718Eleven nene nests were found in Hawaii Volcanoes National Park inthe 1981-1982 breeding season. Eight of these (including one re-nesting effort and one nest found after nesting season) were locatedin the Kalu Desert and three nests were found in the lowlands(elevation 800 m [2625 feet] or less). At least six nesting pairsin the Desert produced 21 eggs, of which nine hatched, and from whichtwo goslings fledged (reached flying age). Three goslings from 10lowland eggs also fledged. Solar radio transmitters placed on threeadult Ka'u Desert ganders near hatching time were used to radio-tracknene families from post-hatching through molt. Two of thethree families moved directly to Kapapa1a Ranch after the eggs·hatched (January 11 and February 3) and remained there until moltbegan (early to late March). Maximum known home range diametersbetween hatching and molt onset were 5.3 and 6.5 km (3.3 and 4.0 mi).Both families (one without the gander) returned to the Ka'u Desertto undergo feather molt. Maximum known home range diameters duringmolt were 5.9 and 7.0 kID (3.6 and 4.3 mi). The third instrumentedgander and family remained in the Kalu Desert after hatching (March 2),and the three young died at less than four, less than 11, and less than14 days, after what seemed inadequate growth. The maximum knownhome range diameter between hatching and onset of molt was 2.5 km(1.5 mi). Both gander and goose began to molt in early April andremained in the Kalu Desert. Maximum known range diameter duringthe molting period for this pair was 3.0 kID (1.9 mi).* ABSTRACT157
