Japanese White-eyes recorded per party hr on the Kapa'a Christmas Count, Kaua'i,
1971-2007 (see Count
Page), indicating a significant decline
through the period. It is
possible that this species
underwent its population peak in the 1940s-1960s and is
now declining, as often occurs
with introduced bird populations in Hawaii.
