[EBB Sightings] Flock of White-throated Swifts in Walnut Creek

Yesterday afternoon at about 4:30, from the parking lot of the Lakeshore Learning Store in Walnut Creek (at Mt. Diablo Blvd and Alpine), I watched a swirling flock of approximately 70-85 twittering, white-throated swifts fly about overhead in a flock that coalesced and largely dissolved several times before I needed to leave about 15-20 minutes after first noticing the flock.  If the swifts all descended into a nearby roost, I was unable to stay long enough to witness it.
