James Easton RRRGroup, "Kenneth Arnold and the pelicans" (Wednesday, April 4, 2007); URL accessed June 27, 2007 was the first of several skeptics to suggest that Arnold may have misidentified pelicans: the birds live in the Washington region, are rather large (wingspans of over 3 meters are not uncommon), have a pale underside that can reflect light, can fly at rather high altitudes, and can appear to have a somewhat crescent-shaped profile when flying.
