I spotted this bird foraging quietly in a flowering Ironwood tree (Olneya tesota) just outside the eastern wall of the mobile home park, where it remained for a few minutes before flying off into the desert to the northeast and disappearing. Although this bird continued to forage in the tree for several minutes, I concentrated on getting at least a few photos rather than studying it carefully. I was therefore able to get several photos, and Louis was able to get a few others, yet I failed to study this bird in extensive detail, so my description of it is necessarily somewhat superficial. The suite of behaviors that we noted from this bird was limited to its hopping about the tree and foraging on the flowers, and we never did hear it vocalize. This was a small to medium-sized passerine that I would have estimated to be somewhat larger than a sparrow yet smaller than a mockingbird. I noted quite clearly that its bill tapered from a base of some depth to a finely pointed tip, and that it had a head of unremarkable size with a gently yet smoothly rounded crown. The neck appeared to be relatively short and inconspicuous, and the body was plump and seemingly full-chested. I failed altogether to note the primary projection or even the length of the wings, but I could see that the tail was of medium-length and that it was parallel-sided. I cannot now recall much of anything about the legs or feet. This was a brightly colored and strikingly patterned bird that was obviously an adult male Baltimore Oriole. Immediately conspicuous was the striking contrast between the jet-black of the entire head, neck, and back with the intense, day-glow orange of the breast, belly, sides, and flanks. I cannot recall noting specifically the color of the undertail coverts or really even the underside of the tail. I was able to see that the back was entirely and solidly black, and that the wings were mostly black, but also with two wingbars that were white in color. Also evident, at least at times, was what appeared to be an orange wedge near the shoulder, but I was unable to determine on what feather tract this color was located. I saw somewhat less clearly additional fringing on the remiges that gave the distal part of the wing a striped pattern, but I am having a hard time remembering the coloration of these fringes. I did notice at one point when the bird spread its tail somewhat that the blackish central-feathers contrasted with bright orange on at least the distal parts of the outer feathers. I cannot however recall noting the color of the rump. I have a reasonably good recollection that the eyes were dark, and thus not contrasting with the black hood, but I am now having a difficult time remembering the colors of the bill, legs, or feet.
