Black-necked (Hawaiian) Stilts recorded per party hr on
the Waipi'o Christmas Count, 1977-2014 (see Count
Page), indicating no particular
trend, but fluctuation related to rainfall levels in the state. Wetter periods
(such as 1976-1984, 1991- 1996, and 2007-2014) are more favorable for stilts than
drought periods (see also Hawaiian Moorhen and Hawaiian Coot). 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/
