First found this morning by Gary Kittleson. Photos, recordings and description to be added to this checklist. The bird was singing off and on from the riparian corridor on both the east and west sides of Sunflower Ln. While the male Red-eyed Vireo was singing, we heard a second vireo scold note (that sounded very similar, if not identical, to the scold of the singing male) coming from near the singing bird. We then observed two vireos together. The singing male was well photographed and recorded, but I did not get diagnostic looks at the second bird. Since these two birds were repeatedly seen together, I think it is safe to assume they represent a pair. Based on the views of the assumed female, I am unable to rule out a hybrid Red-eyed x Warbling. However, other observers got photos of both birds, which should help clarify the identity of the female. As a follow up (18 August), Linda and I are going to only consider the singing male as a Red-eyed Vireo at this point. Others have now reported that the male Red-eyed Vireo is associating with a Warbling Vireo and Tom Hambleton photographed a Warbling Vireo associating with the Red-eyed on the 16th. An interesting paper on this hybrid situation in the western U.S. is here: Interspecific Pair-Bonding and Hybridization In Warbling (Vireo gilvus) and Red-Eyed (Vireo olivaceus) Vireos A Tristan McKee, Dou Yang, Zachary Ormsby, Francis X Villablanca The Wilson Journal of Ornithology 128 (4), 738-751, 2016 See also https://ebird.org/checklist/S29881275 for a photo of a bird identified as a hybrid Warbling x Red-eyed vireo in Colorado for an idea of the potential idenfication challenges associated with this cross.
