coastal Scott's Oriole, overall migrants
I've been doing my loner birding in nicely social-distancing locations and have been seeing a pleasing number of passerine migrants the past several days, as have multiple other observers here in San Diego County and in a good number of other locations in coastal and desert-slope California. Some recent early-morning counts in the mountains and desert-slope in s. CA have been very high. Each day is somewhat different as to what few species are the clear dominant ones. Last Weds it was B-t Grays. Yesterday and today it's been Nashvilles. Also today was a notable up-tick in Western Tanagers, Black-headed Grosbeaks, and both orioles. Today's (Sunday) rarity was a casual-on-the-coast Scott's Oriole (adult male) in residential Point Loma. Also things like Olive-sided Flycatcher, a couple Cassin's Vireos, still a few Hammond's, etc.
On 17 April, there were single FOS Swainson's Thrush and Blue Grosbeak singing in the Tijuana River Valley. Also a Lesser Yellowlegs and Calliope Hummingbird. The late Eurasian Wigeon at the San Diego River mouth stayed through 16 April, but appears gone today.
Starting around this coming Weds there is supposed to be a multi-day E or NE wind and much warmer temperatures. May be good for early-morning flights…or not.
