Albino or leucism in the bird.
Eurasian Collared-Dove x Mourning Dove hybrid. Second of two individuals.
Perhaps a flycatcher or vireo. Identotron suggests least flycather but also includes Hutton's vireo on the list of possiblities. Unfortunately, I could not get a better view of this bird.
wide view shots of the tree show scattering of junipers in the background.
Dove down into the nearby undergrowth several times chasing sparrows and, at one point, a rabbit
3-5 in total
Edit (Feb 6. 2024) Looking back I doubt there were 3-5 and I was maybe mixing different species up. Maybe there were two individuals at most bu I think 3-5 would be an exceptional number of individuals.
