Observation details
scarce but fairly regular breeder; at least two birds were calling in cottonwoods along the water, very distinctive: descending series of four complaining notes, chway chway chway chway; one of these wrangled with a BHVI, which was also nickering, and there were multiple REVI in the area also, so we took care to confirm the identification. One of the candidate PHVI began singing, and this was also quite distinctive (although I often have trouble with this song and have tracked down innumerable REVI that I hoped were PHVI). In this case, the songs were consistently weaker sounding than those of nearby REVI, with shorter and more widely spaced phrases, but similar in overall structure (contra WAVI, for instance). With patience, we were ultimately able to see the singer in the crown of a cottonwood: a vireo with yellow throat and breast, smaller bill and less boldly marked face than REVI; small-looking; no wingbars. Later, at least 1 km to the south, we observed a small bird in alders at eye level in perfect light: another PHVI, with the distinctive yellow tone to the throat and breast, distinctive grayish-green tone to the upperparts, dark transocular, white supercilium, but no black above the last.
