Hawaiian Coots recorded per party hr on the Waipi'o Christmas Count, 1977-2014

(see Count Page), showing an increasing trend through the period. This trend 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).
