"Vireo" is a Latin word referring to a green migratory bird, perhaps the female golden oriole, possibly the European greenfinch.

[2][3] Adults are mainly olive-green on the upper parts with white underparts; they have a red iris and a grey crown edged with black.

[5] The breeding habitat of the red-eyed vireo is in the open wooded areas across Canada and the eastern and northwestern United States.

In northern Ohio, it seems to return to breed at about the same time as one century ago; but it may leave for winter quarters one or two weeks earlier at present than it did in the past.

[6] Red-eyed vireos glean insects from tree foliage, favouring caterpillars and aphids and sometimes hovering while foraging.

[7] They also eat berries, especially before migration, and in the winter quarters, where trees bearing popular fruit like tamanqueiro (Alchornea glandulosa) or gumbo-limbo (Bursera simaruba) will even attract them to parks and gardens.
