The first 10 days of June continued the notable late migration of landbird migrants during Spring 2025. Here's a summary from this latest period, as best I can compile currently.
Olive-sided Flycatcher: one of the best coastal spring migration seasons ever included multiple late birds including five since 5 Jun, with the latest through 9 Jun at Wing Street Canyon
Western Wood-Pewee: this species often occurs in numbers well into the second week of June, and this year was no exception, with, for example, a high total of 28 birds on 10 Jun at Point Loma & Coronado
Willow Flycatcher: this species also normally occurs in numbers well into the second week of June, and this year there were more than the average number seen along the coast (i.e., a few seen daily) where typically quite uncommon
Western Flycatcher: this species also occurs regularly as a migrant into the second week of June, and small numbers continue daily at non-breeding sites
Cassin's Vireo: one photographed in Carlsbad on 7 Jun is probably the all-time late date for a spring migrant
Warbling Vireo: regular into early June, one at Point Loma on 10 Jun was somewhat late
Purple Martin: single females (same bird?) at Cabrillo Nat'l. Monument 4 Jun and at Fort Rosecrans Nat'l. Cemetery 7 Jun are the second/third latest spring record(s) of migrants on record
Cedar Waxwing: singles on 9 Jun at Bay Park and at Point Loma were late
Swainson's Thrush: this species occurs regularly through early, June, and this year seemed to be just average
White-throated Sparrow: a real surprise was one at Rancho Penasquitos on 7 Jun, the second-ever June record
Nashville Warbler: one lingering on Point Loma through 1 Jun was the second-latest ever in spring
MacGillivray's Warbler: one at sea near the 30-Mile Bank on 7 Jun was the third-latest ever
Yellow-rumped (Audubon's) Warbler: one in eastern Carlsbad on 3 Jun was late
Black-throated Gray Warbler: six single very late birds during early June, through 9 Jun, established multiple new latest spring migrant dates ever
Townsend's Warbler: typically the last several migrants are seen into the first few days of June, but many more than normal were present this year, with, for example, 14+ in coastal San Diego Co. on 7 Jun, and still one on 10 Jun at La Jolla Farms tying the latest date
Hermit Warbler: this species was perhaps the poster child for the late migration this year, with small numbers lingering and present daily (including many adult males) well into early June (no precedent for this), and the latest singles on 8 Jun at Point Loma and at Mount Hope Cemetery
Wilson's Warbler: slightly above average numbers through early June
Western Tanager: ditto
Black-headed Grosbeak: nothing exceptional, with a migrant at Fort Rosecrans Nat'l. Cemetery on 8 Jun just slightly late
Lazuli Bunting: one very late female at sea at "The Corner" (32 miles offshore) on 7 Jun
