SOUTHERN CALIFORNIA MBWEEK SUMMARY
April 22 - May 1, 2017
Well, I do have to admit I had doubts during the first few days of this MBWeek that it would turn out better than our January California trips – but after a few more days it became obvious that my initial impression was misguided. Although this trip had never been on the MBW schedule before, and though I had never birded California in spring or visited several of the places on the itinerary, we managed to come up with an impressive list of birds.
In all, we had a respectable total of 221 species (plus one non-countable "white starling"), with an even 100 of these "non-Minnesota" species. By comparison, our January MBWeeks average just under 200 – indeed, note on the list below how many species are marked with an asterisk as being rarer or absent in January. Noteworthy as well is at least five of the birds we saw are strong candidates as future splits: i.e., Willet, Warbling Vireo, White-breasted Nuthatch, Marsh Wren, and Yellow-rumped Warbler – along with some of those Santa Cruz Island endemic subspecies.
With so many birds on our list, it's a challenge to narrow these down into a summary of our most significant highlights. But one place to start is to mention the White Wagtail and Island Scrub-Jay. The wagtail is only Accidental in California, and we were fortunate enough to be in town on the day it showed up on the low-tide mudflats in the San Diego River. On the other hand, the endemic scrub-jay is typically not much of a challenge to find on Santa Cruz Island. But what both have in common is that they represented new additions my life list (at best, I now only manage to see one lifer every year or two), and more significantly they were new additions to the composite MBW list: #707 and 708.
Especially memorable as well was the day we left San Diego when we spent the morning along Kitchen Creek and then visited Jacumba and Fig Lagoon. Our morning highlights included heard-only Mountain Quail (always difficult to see in spring), nice views of a close Gray Vireo, and our best looks at Rufous-crowned and Black-chinned sparrows. Next, in the odd little community of Jacumba, we studied its colony of nesting Tricolored Blackbirds and were surprised by a migrant Hermit Warbler. And we finished the day at Fig Lagoon where a quite unexpected assortment of water birds appeared: a group of 200+ Brant, 21 Common Loons, a Red-throated Loon, and Red-breasted Merganser (all unusual this far from the coast); and as bonuses there were both Clark's and Western grebes, Neotropic Cormorants (rare in CA), and a Least Bittern.
The best highlight in and around the Salton Sea had to be the sub-adult Yellow-footed Gull we finally tracked down between Obsidean Butte and NWR headquarters. This species is hardly ever seen in the U.S. away from the Salton Sea, it is especially elusive in winter and spring, and we were almost distracted at the time by Lesser Nighthawks and Red Knots. We also found a nice assortment of migrants and other birds at the cemetery in Brawley, a Barn Owl roosting in a palm (Guy McCaskie, dean of California birders, found it for us), an abundance of Burrowing Owls, and I was impressed – even if no one else was! – by the tallest flagpole in the Western Hemisphere in below-sea-level Calipatria.
As we headed back west to the Pacific Coast, there was time for more productive birding stops during the next few days. Especially good was Yucca Valley and vicinity, where LeConte's Thrasher was surprisingly easy to find, and where we turned up Lawrence's Goldfinch and Scott's Oriole. Farther west in the San Gabriel Mountains was the Table Mountain-Grassy Hollow area where White-headed Woodpeckers, a Red-breasted Sapsucker, Mountain Chickadees, Pygmy Nuthatches, a partial albino Western Bluebird, and Cassin's Finches were all unexpectedly cooperative – indeed, all but that odd bluebird could be seen simultaneously!
Of course, our boat trip to Santa Cruz Island highlighted our coastal birding at the end of the MBWeek. Not only was the Island Scrub-Jay (found nowhere else in the world) waiting for us, but we also saw 8 of the 11 subspecies endemic to the island (see list below). And en route to or from the island were four species of alcid (especially Scripps's Murrelet) and three shearwaters (especially the Black-vented).
You might think that there couldn't be much to add to all the highlights listed in the paragraphs above, but this summary of memorable birds would certainly be incomplete if it ended here. Especially noteworthy as well were: our luck with being at the right place at the right time as a California Condor drifted overhead by the Los Padres National Forest sign; the pair of California Gnatcatchers in an unremarkable patch of San Diego scrub; Yellow-billed Magpies found more easily than expected at a few sites between Santa Maria and Santa Barbara; the other California specialties such as Ridgway's Rail, Wrentit, California's Scrub-Jay and Thrasher and Towhee, and Bell's Sparrow – and even those Scaly-breasted Munias at Tecolote and Lake Los Carneros deserve honorable mention.
