Common Waxbills recorded per party hr on the Honolulu Christmas Count, 1944-

2014 (see Count Page), indicating increases from 1990 to 2014 following expansion

from initial establishment in w. O'ahu in the 1970s. Fluctuations between years since 1990 may relate to inter-annual variation grass seed production.
