party hr on the Honolulu Christmas Count, 1944- 2007 (see Count
Page), showing significantly declining
populations, perhaps related to increased competition from
other Estrilids See also Moulton and Scioli (1986), Williams (1987), and Ralph
(1990). Graphs of Christmas Count data
developed as part of The Birds of the Hawaiian Islands: Occurrence, History, Distribution, and
