15. Description (include only what was actually seen, not what "should" have been seen; include if possible: total length/relative size compared to other familiar species, body bulk, shape, proportions, bill, eye, leg, and plumage characteristics. Stress features that separate it from similar species): I first saw underparts (mostly undertail coverts and belly) from behind – looked yellowish and longish tailed (I did not see the tail color well because it was folded and almost head-on), and larger than a warbler.  Then I saw the head as it turned its head to the side and noticed the pointed long oriole-like bill, narrow well-defined black throat patch, narrow dark eyeline, and dark nape and crown.  I watched the bird move slowly along the branch and hop to other nearby branches, seeing it at different angles, including front-on and from the side.  I noted the large single bold white wing patch on the folded wing and all yellowish-orange underparts, perhaps getting brighter in the face (auriculars and supercilium).  All the features I saw were consistent with a pure Bullock’s, without obvious introgression of a Baltimore phenotype.

I should note that the bird did not appear as bright orange as in Sibley’s 1st edition, 5th printing (2001), where he depicts the bird to be nearly the same color as Baltimore Oriole.  The bird I saw was more yellow-toned, which seems to be more consistent with the many photos a simple Google Image search revealed.

 

16. Voice: not heard

17. Similar species (include how they were eliminated by your observation): Most like male Hooded or Streak-backed Oriole, but combination of facial pattern, dark nape and crown, and single bold white wing bar clinch Bullock’s.
