Today I birded Sunol Regional Wilderness from 9am until around 12:30pm. As I first crossed the creek onto Camp Ohlone Road, I noted a soaring light-morph adult FERRUGINOUS HAWK. This large, pale bird showed large white patches in the primaries (seen from above) and a gleaming white base to a reddish-tipped tail. It circled with a few vultures quite high up, before heading north. It's getting very late for a Ferruginous Hawk.
My main plan was to walk up the Cerro Este Road from Little Yosemite, to check on the large patch of mimulus flowers for hummingbirds. I was rewarded! Several adult RUFOUS HUMMINGBIRDS were chasing other hummingbirds, and one male gave repeated flight displays. Soon after I noted a nice male CALLIOPE HUMMINGBIRD with its lovely streaked gorget and short tail. Later on I encountered a female as well. I also found a single female BLACK-CHINNED HUMMINGBIRD. She stood out with her more "necked" appearance, gray crown, long slightly decurved bill, faint peachy flanks, and tail that was a bit longer than her folded wings.
I then proceeded to hike up to the Cerro Este overlook, where I noted 3 HORNED LARKS, 3 LARK SPARROWS, 1 GRASSHOPPER SPARROW, and 1 SAVANNAH SPARROW. ROCK WRENS were abundant, and several SHARP-SHINNED HAWKS circled overhead. Over the course of the morning I saw what seemed to be at least 3 individual GOLDEN EAGLES.
