[EBB Sightings] Redwood Regional Park, Oakland, Tues 12/23

>From the Bridle Trail along Redwood Creek in Redwood Regional Park on
Tuesday afternoon, I saw about a dozen VARIED THRUSHES and heard maybe two
dozen more calling.  Struck by these numbers (by far a personal high for
me), I checked eBird and found that the high count for this species in
Alameda County is 100, tallied just a couple of winters ago in this same
park, by Richard Cimino.  Wow!

Nearly equally impressive to me was the spectacle of a couple dozen COMMON
RAVENS engaging in dazzling aerobatics far overhead, and later, toward
dusk, at least 85 ravens streaming in to roost in a grove of tall
redwoods.  This was also a personal high count for me, anywhere.

I thank you for your patience if these numbers are more ordinary to you
than they seemed to me.
