Upated 3/18/2012 – As Otto states in comments, the bird in the water is a Canadian Goose. I regret the misidentification.
One of my few consolations after my mother’s death in 2006 was to visit the Descanso Gardens in La Cañada Flintridge in California.
That is where I took this picture of a duck swimming in one of the ponds on the grounds of the gardens. Click through to Flickr for more photos or visit http://descansogardens.org to plan your visit.
