Hawaiian Coots recorded per party hr on the Waipi'o Christmas Count, 1977-2007

(see Count Page), showing a declining trend, opposite to that of the Kapa'a Christmas Count. These trends may relate to local wetland conditions and/or

increased emigration of birds from Kaua'i to O'ahu. Fluctuations in numbers apart

from the trends reflect favorable and unfavorable conditions for breeding, as related

primarily to rainfall totals (see also Common Moorhen and Hawaiian Stilt).
