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.
