Demography and Movements of Apapane and Iiwi in HawaiiEntry ID: brdpier0005
Abstract: Density, annual survival, philopatry, and movements of two species of
Hawaiian honeycreepers, the Apapane (Himatione sanguinea) and the Iiwi
(Vestiaria coccinea), were studied at four sites on the island of Hawaii.
Highest densities of both species occurred during the breeding season and were
highly correlated with flowering by Metrosideros. Annual survival probability
(the complement of which ... includes permanent emigration) was 0.13 +/- 0.07 for
hatching-year (HY) Apapane, 0.72 +/- 0.11 for adult Apapane, 0.09 +/- for HY
Iiwi,and 0.55 +/- 0.12 for adult Iiwi. Survival of adult Iiwi was the lowest
of six species of native Hawaiian forest birds and may be related to their high
susceptibilty to avian disease. Small resident populations of both species
remained on our study sites throughout the year, but 78% of 1,361 Apapane and
82% of 891 Iiwi were never captured or seen after their initial capture.
Widespread movements of Apapane and Iiwi in response to the seasonal and patchy
availability of Metrosideros nectar have important implications for disease
transmission since Apapane are the primary carrier of avian malaria and avian
pox in Hawaii,and Iiwi appear to be highly susceptible to mortality from
Island of Hawaii at four study areas: Keauhou Ranch (19.52, -155.33; 1,740 m
elevation), Kilauea Forest (19.52, -155.32; 1,630 m), Hamakua (19.78, -155.33;
1,770 m), and Kau Forest (19.22, -155.65; 1,750 m). 1.5.2 Bounding Rectangle
Estimated the density of Apapane and Iiwi using the variable circular-plot
method (Reynolds et al. 1980) during 8-minute counts, as described in Ralph
(1981) and Ralph and Fancy (1994).
Purpose: To determine density, annual survival, philopatry, and movements of two
species of Hawaiian honeycreepers, the Apapane (Himatione sanguinea) and the
Iiwi (Vestiaria coccinea).
