Yellow-throated Vireo in song

Upon arriving in suitable breeding habitat, male Yellow-throated Vireos generally stay in the tops of mature deciduous trees, typically oaks and maples, and sing persistently while foraging. Five to ten minutes may pass before they fly to another tree (James 1996). They have a lovely harsh, burry quality to their song with the ‘hee-o’ notes typically quite far-carrying. The note-pause-note-pause style demonstrates what is termed as immediate variety, in which each subsequent song bout is different from the previous one. I videotaped this Yellow-throated Vireo in song along Frontenac Rd. in Mountain Grove, Ontario on 22 May 2015.
