Description: ``It was a typical `Solitary Vireo' with bold white wingbars and bold white spectacles. The upperparts of the bird were a uniform olive color (including the crown and cheeks), while the underparts were a dingy white with an olivish wash to the sides. The contrast between the olive cheeks and the whitish throat was not sharp but diffused. The bird fed in the cottonwoods in a typical slow vireo fashion...there have been wintering Cassin's Vireos in the Las Cruces area in several of the past five or six years.''
