観察結果の詳細
Plain mid-sized vireo with olive/green back/wings and white underside from throat to undertail coverts foraging in mid to lower level of pine tree. Specific field observations include: dark eye line, large darkish robust bill, dark eye, appeared long-winged and short-tailed, darker tail contrasted with pale undertail coverts, pale supercilium that contrasted strongly with dark eye-line which extended to lores and bill. Warbling vireo was eliminated based on presence of larger bill, presence of dark eye-line that extended to bill and contrasted strongly with supercillium, and presence of greenish/olive color compared to pale/grayish of warbling vireo. Yellow-green vireo was eliminated based on smaller darker bill, lack of yellow flanks, and presence of darker more contrasting eye-line.
