Vaux's Swifts Balboa Park

This evening (1/24), right at sunset (5:10 PM), there was a unseasonable flock of chattering Chaetura swifts circling over the El Prado bridge over Hwy 163 in Balboa Park. I assume Vaux's; 2 or 3 dozen. They seemed to be gathering to roost nearby. They headed off to the south-southeast.
