About the Yellow-green Vireo

The yellow-green vireo (Vireo flavoviridis) is a small American passerine bird. It is migratory breeding from Mexico to Panama and wintering in the northern and eastern Andes and the western Amazon Basin. The yellow-green vireo was formally described by the American ornithologist John Cassin in 1851 under the binomial name Vireosylvia flavoviridis. The specific epithet combines the Latin flavus meaning "yellow" and viridis meaning "green". The type locality is San Juan de Nicaragua. The yellow-green vireo is now placed in the genus Vireo that was introduced in 1808 by the French ornithologist Louis Pierre Vieillot.

Four subspecies are recognised: V. f. hypoleucus Van Rossem & Hachisuka, 1937 – northwest Mexico (southeast Sonora to south Sinaloa) V. f. flavoviridis (Cassin, 1851) – central north, northeast Mexico to Panama V. f. forreri Madarász, G, 1885 – Islas Marías (off west Mexico)

V. f. insulanus Bangs, 1902 – Pearl Islands (Gulf of Panama) The adult yellow-green vireo is 14–14.7 cm (5.5–5.8 in) in length and weighs 18.5 g (0.65 oz). It has olive-green upperparts and a dusky-edged gray crown. There is a dark line from the bill to the red-brown... Wikipedia →
