Hawaiian Coots recorded per party hr on the Honolulu
Christmas Count (see Count
Page) in 1944-2014. The drop in numbers since
1960 reflects, among other things, the loss of wetland habitat in se. O'ahu, in particular, the draining of Kaelepulu Pond in 1954. See
also Northern Pintail and Northern Shoveler. Graphs of Christmas Count data developed as part
of The Birds of the Hawaiian Islands: Occurrence, History, Distribution, and
Status by Robert L. Pyle and Peter Pyle http://hbs.bishopmuseum.org/birds/rlp-monograph/
