My discovery of the Philadelphia Vireo seemed to mark the tail end of a good pulse of eastern vagrants through the county, although most of these were frequent ones like Tennessee or Blackpoll Warblers. Other than enjoying the continuing flow of Cassin’s Finches, Clark Nutcrackers and Pinyon Jays from the montane bird invasion, the next few days brought little of interest, although I did twitch a Chestnut-sided Warbler – an annual vagrant to the county - at the Hollister Tech Park on Sep 27. Things started to look up that evening when a return check of the Tech Park turned up a nice male American Redstart – most birds we see are in female or immature plumage. As a change from vagrants from the east, the next morning Sophie Cameron and I found our first Tropical Kingbird of the fall during a survey at Laguna Blanca. This Mexican species is a frequent vagrant during the fall as birds reverse migrate north up the Pacific Coast and typically several birds spend the winter. Noting...
2026 has been proving to be a productive year for additions to my Santa Barbara county list. Most of the more ‘gettable’ additions are seabirds, assuming I can stomach going on enough pelagic trips. Among the potential passerine vagrants I had yet to see, Philadelphia Vireo stood out as one that I should get sooner or later. However, after 26 years in the county with only one chaseable bird that I had missed, it seemed far from inevitable that I would see one. Ironically, when I first moved to California in 1992, Philadelphia Vireo was the first CBRC rarity that I found – a bird at Andrew Molera State Park on the Big Sur coastline of Monterey County. A few years later, the CBRC removed this species from their review list as it had proven to be a fairly regular vagrant. However, Philadelphia Vireo occurs much more frequently in the (San Francisco) Bay Area than they do along the southern coast of California. During my time in the county, there had been only three records, so about six...
