Their throat and upper breast are grayish white and the rest of their underparts pale yellow. Voice: The brown-capped vireo's song has been described as "a short, sweet 2.5-3-sec. warble, similar to Warbling Vireo song", "a silky, ripping, and somewhat hurried little refrain, here you sée me hear me sing so swéet", and "a hesitating, pleasant warble of variable pattern...wurlze-wee-wee wurzle-weezle-wee wurzle-wee". One description of its call is "a wheezing, descending zreeEEEEw".
