Howell, T.R. 1946 Cygnus columbianus Dec. 14 Sacramento National Wildlife Refuge elev. 100 ft, Glenn Co., Calif. Slightly over 30 individuals of this species were seen on the Refuge, most of which were in one flock. About 1/4 of these were young birds in dingy grayish plumage. The adults seem to have a wash of yellowish or pinkish color over the head and upper neck. I could not make out the yellow spot on the [illegible], but they were all at long range. The call note is a distinctive "hooting honk", deeper and altogether different from that of a goose. They take off from the water only with some difficulty, as they paddle the water with their feet like coots. once aloft, flight is quite easy.
