The Goslings of Bird Poop Rock

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.

Spring is a time of heightened avian activity across the globe. In the oak woodland foothills of the Sierras near Yosemite National Park, bird migration and nesting activity is at its peak. Wild Turkey toms are strutting from dawn to dusk in hopes of attracting females for copulation. Sometimes competition between males becomes violent. See it all in still and video photography in this post.

If you’ve ever taken a drive out of the city into the countryside, you may have seen this bird of prey standing watch on a utility pole.

Acorn Woodpeckers are the voice of the oak woodland foothills of the Sierra where I live. You can’t miss hearing their calls throughout the day. In spite of the name, acorn woodpeckers feed primarily on insects. During winter months, when insects are less prevalent, they rely upon communal acorn granaries, thousands of holes drilled into utility poles. Photo illustrations.
