Cattle Egrets recorded per party hr on the Kapa'a Christmas Count, Kaua'i, 1971-

2014 (see Count Page). The data indicate declines (both here and on the Honolulu and Lihue Christmas Counts) after initial island-wide expansion in population and abundance, beginning with release in1959 and peaking around 1980. Despite the declines, Cattle Egrets remain a common sight in Hawaii and are regarded as pests, posing hazards to aircraft and predating the nests of native waterbirds.
