Allen's / Rufus Hummingbird ?

Mike Correll-Feichtner

Today, 30 May 2021, I spotted a female Selphasphorus Hummingbird first perched on a snag and then later stayed low in the berry vines, never coming back into the open.

How unlikely would this be a Rufus Hummingbird?

This was in Eastern Alameda County in the Pleasanton Ridge Regional Park along the Courdet Trail.
