National Geographic : 1919 Oct
Photograph by Joseph Dixon CANVASBACKS, PINTAILS, AND BALDPATES ON LAKE MERRITT, OAKLAND, DURING AFOGGY MORNING Some idea of the number of wild ducks which winter on Lake Merritt may be had from the aboveillustration, which represents only aportion, about 1,500, of the total number. On December 28, 1918, there were 5,000 wild ducks on the lake and adjacent lawns. At this date Pintails and Canvasbacks constituted two-thirds of the total number. The number of Canvasbacks this year was atleast 50per cent greater than itwas inthe preceding year. The above figures are based on actual counts by various persons and are not mere guesses. Note the long, slightly up-curved tail of the Pintail (lower left margin of picture) and the sharp, stubby, tipped-up tail ofthe Baldpate (lower center). The Canvasback (lower right) shows no tail at all to speak of.
