Detalles de la observación
Photo and recordings. Gray colored vireo with slightly greenish yellow sides. Song is burry but faster than Plumbeous -- Edit: Upon later investigation some sources claim that the two species cannot be distinguished by ear. However, I suspect it can be done, need to listen to more recordings, unfortunately quality is not good enough for detailed spectrographic analysis (left the microphone in the car!). The slight olive tinge to the flanks and yellowish in undertail area suggests Cassin's more than Plumbeous, imo, although the back was quite gray, not olive. Plumbeous vireos I've seen had no olive/yellow at all on underside.
