Black-necked (Hawaiian) Stilts recorded per party hr on
the Kapa'a Christmas Count, 1971-2014 (see Count
Page), indicating a significantly
increasing trend, opposite to that of the Honolulu Christmas Count. 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 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/
