This juvenile Parasitic Jaegar appeared at the shell bar in Foster City to chase terns around some, providing terrific looks! Photo by guide Chris Benesh.
Few places in the United States have the diversity of habitats and experiences as can be found in California. Our Slice of California: Seabirds to Sierra tour is designed to maximize the birding experience while minimizing the distance covered to sample from a diversity of habitats. Our 2018 offering was another success. The weather was generally good as is usually the case this time of year. In fact, we saw first hand the effects of California’s ongoing drought by way of another massive fire from earlier in the summer that had some of the higher sections of Highway 120 closed off. We also narrowly dodged a new blaze near Bridgeport that had our return route closed off until the day before we were set to head westward again. Yikes!
Fires aside, all was good. The birds were plentiful and some of our encounters were truly spectacular! The Mountain Quail encounter in Bear Valley was epic! The Laysan Albatross that appeared on the pelagic trip was a stunner, though it had to compete with Blue Whale for most exciting pelagic encounter. The graceful Buller’s Shearwaters deserve a mention too, elegantly cutting through the air. While we saw all three jaegers, it was the Parasitic that provided some wonderful views, both at sea and in the harbor and San Francisco Bay! Back on shore, highlights included seeing both Bell’s and Sagebrush sparrows (to contemplate the differences), seeing chickadees and nuthatches among Giant Sequoias, California Thrasher, Wrentit, Yellow-billed Magpie, Pinyon Jay, and a plethora of woodpeckers with the likes of Lewis’s, Black-backed, White-headed, Nuttall’s, Pileated, and two species of sapsucker. Seeing Greater Sage-Grouse in the setting of historic Bodie was a treat too, as was the huge flock of Vaux's Swifts coming to roost in San Rafael.
Thanks to all of you for making the tour such a success! I look forward to seeing you again on the next adventure! — Chris
