Détails de l'observation
Nearly the full range of variation in this species represented by individuals present, from "blue-headed" to green to fairly dull. See photos. This species is expected at this site at this time of year. "Solitary" type vireos, bold spectacles. All showing significant yellowish flanks. One individual quite green all over, all showing at least some green in secondary wing feathers. One showing bluish head but demarcation between head and white throat very gradual, not sharp (see photos). Lots of experience with all members of Solitary group, saw one Plumbeous this visit, which showed all dark gray upperparts with only the slightest hint of yellow on the flanks.
