Common (Hawaiian) Moorhens recorded per party hr on the Lihue Christmas Count

(see Count Page) in 1972-1991. This species has shown similar fluctuations in

populations on the Kapa'a and Waipi'o Christmas Counts, related to rainfall levels in

the state. Wetter periods (such as 1976-1984 and 1991-1996) are more favorable for

moorhens than drought periods (see also Hawaiian Coot).
