Black Swift, Ventura Settling Ponds, CA - 10 May 2021
Détails de l'observation
Six flew by going north and another two showed up a few minutes later and lingered around the southern edge of the ponds. Large dark swifts that were frequently gliding with slow shallow wingbeats. The distinctive flight is what caught my eye at a distance before several came over and provided closer looks. Some of the birds, including those pictured, showed whitish scaling on the belly and undertail coverts. Are they retaining juvenile plumage in their second year?
