Every Spring, Canada Geese nest around Blue Heron Lake in the oak woodland foothills near Yosemite National Park. Of the nine nests I observed this year, four were destroyed by predation during the night. One nest, containing five eggs, and situated upon a granite boulder submerged in the lake, seemed destined for success because of its immunity from terrestrial predators. From the beginnings of the nest to the hatching of an egg, in this article, illustrated with photos and video, you will experience the dramatic details of what I observed over approximately five weeks.
