In case anyone is interested, in reviewing various additional recordings of E.
Yellow Wagtail, I found this that even more closely matches the bird I heard at
South Jetty - the first alarm/flight call in this recording:

I heard one flight call (but did not see) an EASTERN YELLOW WAGTAIL this
morning at the South Jetty, about 8 am. About 200 yards beyond Parking Area C,
where the level gravel trail ends in the sandy Salicornia pond area, left over
the jetty. Very like this recording: https://www.xeno-canto.org/127900 but ;
even more emphatic. The burry downward note was very distinctive. Also in the
area were a/the flock of 15+/- LAPLAND LONGSPURS (nothing in with them that I
could see) and 5-6 WATER PIPITS. Try as I might, I never heard the wagtail
again in almost an hour in the area.
Offshore was active with expected regulars. Also a glimpse of a smallish
whale, presumably GRAY.
At Parking Area D blind area were 15+/1 SEMIPALMATED PLOVERS, a BAIRD'S
SANDPIPER, 5-6 WESTERN S., two BLACK-BELLIED PLOVER and several DUNLIN, also a
BALD EAGLE, among expected gulls, NO. PINTAILS and some AMER WIGEON.
